New data on algae, bryophytes, fungi and lichens of Italy 127 Floristic records ALGAE Chara gymnophylla A.Braun (Characeae) + CAL: Parco della Biodiversità Mediterranea, along the “Rizzitano Trail” at the height of the equestrian center (Catanzaro) (UTM WGS84: 33S 636590.4308890), seepage of groundwater on the soil, 260 m, 4 June 2023, leg. A. Capuano, det. R. Romanov (NHMM). – Species new for the flora of Calabria. A small population was found thriving in a temporary humid spot, along a disturbed trail colonized also by hygrophilous vascular species. Heavily calcite-incrusted plants had condensed general habit because of shortened internodes. Dense placement of ecorticate branchlets with long unilateral bract-cells and conjoined gametangia hid isostichous to weakly aulacanthous diplostichous axial cortex with short solitary spine cells. According to Schubert et al. (2024), C. gymnophylla is considered as a species distinct from C. vulgaris L. in having corticate branchlets and branchlet nodes with bract-cells and gametangia between and at the top of upper corticate segments of branchlets only, and distinct from C. squamosa Desf. in having tylacanthous axial cortex. Currently, this species has been reported from Veneto, Liguria, Umbria, Lazio, Sicilia, Toscana, and recently from Abruzzo (Bazzichelli and Abdelahad 2009; Ravera et al. 2019, 2022, 2024). R. Romanov, A. Capuano Chara squamosa Desf. (Characeae) + LOM: Stelvio National Park, Valdidentro (Sondrio) (WGS84: 32T 594581.5159288), temporary pond, 1853 m, 19 June 2025, leg. G. Patera, det. R. Romanov, G. Patera (NHMM). – Species new for the flora of Lombardia. Chara squamosa is currently known in Italy only from Sicilia, Sardegna, and Calabria (Romanov et al. 2019, 2024). The present record represents the first finding for Lombardia and, more broadly, a new record for Central-Northern Italy. The observed population developed within a small alkaline oligotrophic pond on silty substrate located on a fluvial terrace along the stream “Acqua del Gallo”, in contact with alpine pioneer formations of Caricion bicoloris-atrofuscae characterized by Carex microglochin Wahlenb. and C. simpliciuscula Wahlenb. G. Patera, R. Romanov Hildenbrandia rivularis (Liebmann) J.Agardh (Hildenbrandiaceae) + TAA: River Brenta, Municipality of Novaledo (Trento) (UTM WGS84: 32T 683964.5099229), 422 m, 23 January 2024, D. Spitale (TR). – Species new for the flora of Trentino-Alto Adige. Sonia Ravera / Italian Botanist 20: 125–148 (2025) 128 + EMR: Spring Nove Fontane on the Monte Nero, Municipality of Bedonia (Parma) (UTM WGS84: 32T 541341.4934295), 1509 m, 4 August 2025, M. Cantonati (BOLO). – Species new for the flora of Emilia-Romagna. The historical records of this species are summarized by Ceschin et al. (2013), and concern Veneto, Toscana, Lake Garda, and the central Apennines. These authors added a record for Abruzzo, while Cantonati et al. (2012) found it in five springs (sampled in 2005–2006) in Trentino, and Cantonati et al. (2020) in four springs (sampled in 2011) in Emilia, but no formal report was published. It is a scyaphilic, epilithic species (Cantonati et al. 2016) occurring from oligo - to eutrophic (Gutowski and Foerster 2009), and from saprobically unaffected to moderately-affected waters (Rott et al. 1999). According to the current German Red List for red algae it is not threatened (Foerster et al. 2018). M. Cantonati, D. Spitale Pleurotaenium trabecula Nägeli (Desmidiaceae) + CAL: Foresta demaniale alto Aspromonte, Villaggio Canovai, Samo (Reggio Calabria) (UTM WGS84: 33S 564463.4224289), in a pond within the Calabrian pine forest used for the repopulation of the Apennine yellow-bellied toad, 1320 m, 22 August 2025, F. D’Aleo (REGGIO). – Species new for the flora of Calabria. This species has been reported in Italy by Abdelahad et al. (2003), but they did not record it in Calabria. This is also the first record for southern Italy. F. D’Aleo, C.M. Musarella, R. Bonanno Spirogyra neglecta (Hassall) Kützing (Spirogyraceae) + CAL: Pellaro, contrada Pantano (Reggio Calabria) (UTM WGS84: 33S 558200.4207886), in a pond inside a puddle at the base of a fountain with a trough, 120 m, 5 September 2025, F. D’Aleo (REGGIO). – Species new for the flora of Calabria. This species is similar to Spirogyra ternata Ripart, which, however, could represent a variety, and it is distinguished by the zygospore orientation. In S. neglecta, the chloroplasts are 3, making 2.5 turns of the cell. In Europe, this species is reported in Belarus (Mikheyeva 1999), Britain (Brook and Johnson 2002; Pentecost and Haworth 2021), Britain and Ireland (Whitton et al. 2003; John et al. 2011), Latvia (Skuja 1928), Netherlands (Veen et al. 2015), Romania (Caraus 2017), Slovakia (Hindák and Hindáková 2016), Slovenia (Vrhovsek et al. 2006), Ukraine (Barinova et al. 2019; Tsarenko et al. 2024). However, in Italy this species was reported on GBIF (2025) in Piemonte with a herbarium specimen from the Natural History Collections of the Faculty of Biology AMU, Adam Mickiewicz University in Poznań, dated before the 20th century (POZA-0008821). This is the first preserved specimen entirely in alcohol and therefore suitable for evaluation. F. D’Aleo, C.M. Musarella, R. Bonanno New data on algae, bryophytes, fungi and lichens of Italy 129 BRYOPHYTES Braunia alopecura (Brid.) Limpr. (Hedwigiaceae) + PIE: Ossola Valley, Genestredo, Vogogna (Verbano-Cusio-Ossola) (UTM WGS84: 32T 446644. 5094962), 320 m, mafic granulite, 3 July 2025, S. Scortegagna (MNAV). – Species confirmed for the flora of Piemonte. Braunia alopecura is a rare species in Italy, where recent confirmations exist for Lombardia and Trentino-Alto Adige but not for Valle d’Aosta, Liguria and, Piemonte (Aleffi et al. 2023). In the latter region, particularly in Ossola Valley, this species has been observed with abundant populations in sunny outcrops of mafic granulites together with other notable species such as Brachythecium geheebii Milde, Campylopus pilifer Brid., Campylopus oerstedianus (Müll.Hal.) Mitt., and Hedwigia ciliata (Hedw.) Beauv. The recorded locality is in geographical continuity with the Swiss ones, which are located in the Cantons of Ticino and Graubünden (Swissbryophytes 2004–2025). In the recent Italian Red List by Puglisi et al. (2024) the species has been considered as Vulnerable (VU). S. Scortegagna Buxbaumia viridis (Moug. ex Lam. & DC.) Brid. ex Moug. & Nestl. (Buxbaumiaceae) + EMR: Monte Cantiere, Lama Mocogno (Modena) (UTM WGS84: 32T 631330.4903578), on dead wood of Picea abies (L.) H.Karst., 1545 m, 3 May 2025, G. Pandeli (CAG; SIENA). – Species confirmed for the flora of Emilia-Romagna. + TOS: Loc. Le Regine, Abetone (Pistoia) (UTM WGS84: 32T 634703.4887650), on a rotting wood of Picea abies (L.), 1327 m, 3 August 2025, G. Pandeli (SIENA; Herb. Pandeli); Loc. Cecchetto, Abetone (Pistoia) (UTM WGS84: 32T 636233.4887382), on rotting logs of Picea abies (L.) H.Karst., 1196 m, 22 March 2024, G. Pandeli (SIENA; Herb. Pandeli); Fosso dell’Abetina, Abetone (Pistoia) (UTM WGS84: 32T 634138.4889367), on dead wood of Picea abies (L.) H.Karst. and Abies alba Mill., 1345 m, 31 July 2025, G. Pandeli (SIENA; Herb. Pandeli); Valle delle Pozze, Abetone Cutigliano (Pistoia) (UTM WGS84: 32T 630775.4889912), on dead woody debris of Picea abies (L.) H.Karst. and Abies alba Mill., 1324 m, 10 May 2022, G. Pandeli (SIENA; Herb. Pandeli); Monte Gomito, Abetone (Pistoia) (UTM WGS84: 32T 632417.4889240), on rotting logs of Abies alba Mill., 1320 m, 21 August 2001, I. Bonini (SIENA). – Species confirmed for the flora of Toscana. Buxbaumia viridis is a small epixylix moss (Puntillo and Puntillo 2024), protected in Europe and Italy (listed in Annex I of the Bern Convention and in Annex II of the Habitat Directive 92/43/CEE) and currently recorded in Valle D’Aosta, Piemonte, Lombardia, Trentino Alto-Adige, Friuli Venezia Giulia, Lazio, Abruzzo, Campania, Calabria (Aleffi et al 2023), with old records for Emilia-Romagna (Fiori 1886), Toscana (De Notaris 1869; Fiori 1886; Bottini 1887), and Veneto (Massalongo 1896; Saccardo 1872). These new records confirm the occurrence of Sonia Ravera / Italian Botanist 20: 125–148 (2025) 130 this species in Emilia-Romagna and Toscana after about 140 years since the last findings (De Notaris 1869; Fiori 1886; Bottini 1887; Fariselli et al. 2024). All the citations in more recent works (Castaldo 1972–1973; Beni 1983) are not original and refer to nineteenth century records. G. Pandeli, I. Bonini, M. Aleffi Crossidium squamiferum (Viv.) Jur. (Pottiaceae) + VEN: M. Pallone, Trissino (Vicenza) (UTM WGS84: 32T 683969.5049979), 310 m, sunny and arid basaltic outcrop, 16 March 2025, S. Scortegagna (MNAV). – Species confirmed for the flora of Veneto. + MOL: Montenero di Bisaccia (Campobasso) (UTM WGS84: 33T 482169.4644576), 240 m, road embankment, 7 June 2025, S. Scortegagna (MNAV). – Species confirmed for the flora of Molise. Crossidium squamiferum is a submediterranean species occurring in almost all Italian regions, but in many of them, including Veneto and Molise, there are no confirmation after 1968 (Aleffi et al. 2023). This is probably a species in real decline, as indicated by its VU status, with an estimated reduction of more than 30%, in the Swiss Red List by Schnyder et al. (2004). In Italy, however, it has been classified as Least Concern (LC) by Puglisi et al. (2024). S. Scortegagna Dicranum flagellare Hedw. (Dicranaceae) + EMR: Modena Apennines, Monfestino, Serramazzoni (Modena) (UTM WGS84: 32T 645332. 4921337), 640 m, 7 March 2025, rotting chestnut stump, S. Scortegagna (MNAV). – Species new for the flora of Emilia-Romagna. Dicranum flagellare is a saprolignicolous and, more rarely, corticolous species, reported for all the Alpine regions from Valle d’Aosta to Friuli Venezia Giulia (Aleffi et al. 2023), but thought to be absent further south. This is therefore the southernmost record of this species in Italy. This species was detected in its preferred habitat, represented by rotting stumps in a chestnut-dominated forest. In the recent Italian Red List by Puglisi et al. (2024) the species has been considered as Least Concern (LC). S. Scortegagna Flexitrichum gracile (Mitt.) Ignatov & Fedosov (Flexitrichaceae) + ABR: Marsica Mts, Moricento beach wood, Lecce nei Marsi (L’Aquila) (UTM WGS84: 33T 392182.463416), 1730 m, limestone outcrop in beech forest, 23 July 2019, S. Scortegagna (MNAV); Marsica Mts, Mt. Serrone, Pesco di Iorio Valley, Pescasseroli (L’Aquila) (UTM WGS84: 33T 394573.462796), 1830 m, limestone outcrop in pasture, 16 June 2024, S. Scortegagna (MNAV). – Species new for the flora of Abruzzo. New data on algae, bryophytes, fungi and lichens of Italy 131 Flexitrichum gracile has not always been distinguished from the related F. flexicaule (Schwägr.) Ignatov & Fedosov (Frisvoll 1985), and this fact may explain the discontinuity of its records, many of which have not been confirmed in recent times (Aleffi et al. 2023). The observed populations are quite plentiful. In the recent Italian Red List by Puglisi et al. (2024) this species has been considered as Least Concern (LC). S. Scortegagna Tortella angustifolia (Jur.) Köckinger & Hedenäs (Pottiaceae) + VEN: Dolomites, Livinallongo del Col di Lana, Passo Pordoi (Belluno) (UTM WGS84: 32T 716064.5151725), on limestone below trail 601, 2230 m, 2 July 2025, leg. A. Schäfer-Verwimp, I. Verwimp, det. A. Schäfer-Verwimp 42807 (BOZ, JE). – Species new for the flora of Veneto. Tortella angustifolia is a recent segregate of the Tortella tortuosa-complex. It is widespread in the Alps, often found from the low montane to the subnival belt (Köckinger and Hedenäs 2023). The first record of the species in Italy comes from Südtirol/Trentino-Alto Adige (Schäfer-Verwimp et al. 2025). A. Schäfer-Verwimp, P. Mair Tortella commutata Köckinger & Hedenäs var. commutata (Pottiaceae) + VEN: Dolomites, Livinallongo del Col di Lana, Passo Pordoi (Belluno) (UTM WGS84: 32T 716000.5151850), on sunny limestone alongside trail 601, 2265 m, 2 July 2025, leg. A. Schäfer-Verwimp, I. Verwimp, det. A. Schäfer-Verwimp 42800 (BOZ, JE); Passo Campolongo (Belluno) (UTM WGS84: 32T 720333.5155597), on sunny limestone, 1870 m, 2 July 2025, leg. A. Schäfer-Verwimp, I. Verwimp, det. A. SchäferVerwimp 42824 (JE). – Species new for the flora of Veneto. Tortella commutata, another segregate of the Tortella tortuosa-complex, is by far the most common species of the complex in central Europe (Köckinger and Hedenäs 2023). It has a wide ecological amplitude and is found in both natural and man-made habitats, such as murals and roofs. The first record for Italy was by Köckinger and Hedenäs (2023) from Trentino-Alto Adige and subsequently found to be rather common in South Tyrol by Schäfer-Verwimp et al. (2025). A. Schäfer-Verwimp, P. Mair Tortella fleischeri (E. Bauer) J.J.Amann (Pottiaceae) + VEN: Dolomites, Livinallongo del Col di Lana, Passo Valparola (Belluno) (UTM WGS84: 32T 729128. 5158199), on limestone beside Pinus mugo, 2125 m, 29 June 2025, leg. A. Schäfer-Verwimp, I. Verwimp, det. A. Schäfer-Verwimp 42743 (BOZ, JE). – Species new for the flora of Veneto. Sonia Ravera / Italian Botanist 20: 125–148 (2025) 132 Tortella fleischeri is a cryophilous species of the Tortella tortuosa-complex. It prefers sites at or above the treeline of the calcareous mountain ranges (Köckinger and Hedenäs 2023). In Italy, however, this species does not appear to be as common as in the Austrian Alps. The first record comes from the administrative region of TrentinoAlto Adige/Südtirol (Köckinger and Hedenäs 2023), followed by a single record from South Tyrol by Schäfer-Verwimp et al. (2025). A. Schäfer-Verwimp, P. Mair Ulota coarctata (P.Beauv.) Hammar (Orthotrichaceae) + TAA: Lases, in loc. Buse del Giac (Trento) (UTM WGS84: 32T 672001.5112468), su ramo di Alnus alnobetula (Ehrh.) K.Koch), 755 m, 25 June 2024, F. Prosser (ROV 08251). – Species confirmed for the flora of Trentino-Alto Adige. This finding is located within the SCI/SAC area “Lona - Lases” (IT3120049) and falls in a cold microclimate valley on porphyritic substrate. The microclimate here causes considerable bryophyte development, which also affects the branches of trees and shrubs. Despite previous bryological research (Pfaff 1933), this species had never been found at this site. Regionally, there was only one previous historical report for the Spronser Valley near Merano (Bamberger in Dalla Torre and Sarnthein 1904). According to Aleffi et al. (2023) this is a confirmation also for the whole of northern Italy. F. Prosser FUNGI Agaricus boisseletii Heinem. (Agaricaceae) + CAM: Arpaise (Benevento) (UTM WSG84: 33T 478143.4541329), in a Graveyard garden, on soil beneath Cupressus sempervirens L., 468 m, 10 November 2023, M. Zotti, G. Martino (PORUN). – Species new to Campania. Several specimens were found at the site, either growing singly or in clusters. Upon sectioning, the basidiomes turned a wine-red color throughout the entire cut surface, with particularly intense staining in the central area of the pileus and along the stipe margins. The lamellae displayed a lamellar edge characterized by whitish granulations interspersed with ochraceous dots. Microscopic examination revealed distinctive catenulate cheilocystidia. Agaricus boisseletii is a rare species typically associated with Cupressus spp. litter, although not exclusively. It was first described in France (Heinemann 1987) and later reported in Portugal (Parra 2008). This species was previously recorded only once in Italy, in Toscana (https://www.gruppomicologicosaccardo.org/ erbario/4788-agaricus-boisseletii.html). Our finding is the first record for Campania region and for southern Italy as a whole. M. Zotti, I. Catalano, G. Martino New data on algae, bryophytes, fungi and lichens of Italy 133 Coltricia cinnamomea (Jacq.) Murrill (Hymenochaetaceae) + CAL: Mammola (Reggio Calabria) (UTM WGS84: 33S 606424.4246763), on the rocky vault of a mine among the roots of overhead Quercus ilex L. trees, 290 m, 28 April 2023, G. Sicoli, N.G. Passalacqua, D. Gargano (CLU F341). – Species new to Calabria. A few pileate and centrally stipitate basidiomes were found separately attached to and sprouting from the rocky vault of a mine at about 10 m from the entrance, among roots presumably belonging to holm oak trees just standing overhead. Pilei were funnel-shaped, 2to 4-cm wide, cinnamon-coloured, zoned and shiny above, below showing a poroid and rusty hymenophore (pores 2–5 per mm), decurrent on a finely velvety, coriaceous and brownish stipe. Hyphae were rust-brown, thick-walled and smooth, septate and clampless. Spores were smooth, subglobose to broadly ellipsoid, pale yellowish, 6.5–8.0 × 4.5–6.0 µm sized. Therefore, the fungus was identified as Coltricia cinnamomea, a non-common basidiomycete, but reported from several countries around the world, including southern Europe, ectomychorrizal on angiosperms in the tropics (Tedersoo et al. 2007; Dai 2010; Tarafder et al. 2017). In Italy it seems occurring only in the north, besides Toscana and Sardegna (Onofri et al. 2013). G. Sicoli, N.G. Passalacqua, D. Gargano Cortinarius biriensis Brandrud & Dima (Cortinariaceae) + LIG: Verlia, Sassello (Savona) (UTM WGS84: 32T 459963.4924331), on calcareous soil under white hornbeam (Carpinus betulus L.) and hazel (Corylus avellana L.), 484 m, 28 May 2023, F. Boccardo (GDOR5413). – Species new to Liguria. Morphologically, our Ligurian collection fits well with the description of the C. biriensis reported in Brandrud et al. (2017). The newly nrITS sequence of the GDOR5413 voucher (GB: PX314714) shares 651/651 (100%) nucleotides compared with the holotype of C. biriensis sequence (GB: KX831118) confirming the morphological identification. According to Brandrud et al. (2017), C. biriensis has been reported from Estonia and Norway, and our collection is the first collection of this species in Liguria with molecular confirmation. The BLAST analysis on the UNITE database includes an environmental ITS sequence (UDB04242715) that shows a 100% identity (505/505pb) with our sample, suggesting that this species is also present in Sicilia. F. Boccardo, F. Dovana Gliophorus irrigatus (Pers.) A.M.Ainsw. & P.M.Kirk (Hygrophoraceae) + CAL: Botanical Garden of the University of Calabria, Rende (Cosenza) (UTM WGS84: 33S 605997.4357299), on the ground among the litter of Downy oak (Quercus pubescens Willd.) trees, 204 m, 6 December 2024, N.G. Passalacqua, A.B. De Giuseppe, G. Sicoli (CLU F343). – Species new to Calabria. Sonia Ravera / Italian Botanist 20: 125–148 (2025) 140 Graphis pulverulenta is an epiphytic crustose lichen belonging to the G. scripta group. It is distinguished by its apothecia, which typically have sharply pointed ends and conspicuously exposed discs covered with a white to greyish pruina. Although morphologically close to G. scripta, the taxonomic boundaries within this complex remain uncertain. Pending a detailed revision of the Italian specimens, G. pulverulenta is provisionally treated as a distinct species by Nimis (2025). S. Ravera, M. Agostini, L. Di Nuzzo Leptochidium albociliatum (Desm.) M. Choisy (Massalongiaceae) + TOS: Sorgente Bugnano, the foot of Mt. Amiata, Seggiano (Grosseto), forest of Castanea sativa Mill. with ancient trees (UTM WGS84: 711607.4753262), on soil and among bryophytes, 980 m, 12 September 2025, leg. A. Guttová, L. Paoli, det. A. Guttová (SAV0021566). – Species new to Toscana. Leptochidium albociliatum is a lichen with gelatinose, small-foliose thallus, dark brownish, blackish to olive-green thallus forming cushions up to 8 cm. The margins of rounded lobes are lined with white hairs, very well visible under the hand lens and the lamina of the upper thalline surface bears vegetative propagules – granular isidia. The specimen is also fertile with several young as well as mature (convex disc) apothecia (diameter up to 1.5 mm). Apothecial disc is reddish-brown, the proper margin is lined with white hairs. Narrowly-ellipsoid spores (18–20 × 6–7 µm) are hyaline, with one septum. Pycnidia were not observed. Lower surface with white, fasciculate hapters (Ismailov and Urbanavichus 2024; Nimis 2025). L. Paoli, A. Guttová Melanelia stygia (L.) Essl. (Parmeliaceae) + BAS: Monte Volturino, Marsicovetere (Potenza) (UTM WGS84: 33T 569330.4472730), on siliceous rocks, 1533 m, 11 July 2011, G. Potenza, S. Fascetti, D. Puntillo (HLUC 805). – Species new to Basilicata. It is a circumpolar, arctic-alpine lichen, in Italy found in open habitats on siliceous rocks, with optimum near and above treeline; widespread in the Alps where it reaches the nival belt, it is much rarer in the high Mediterranean mountains. Specimens from Calabria and Sardegna (herbarium TSB) are worthy of further study (Nimis 2025). G. Potenza, D. Puntillo, S. Fascetti Rinodina albana (A.Massal.) A.Massal. (Physciaceae) + CAL: on NW-facing slope of Mt. Timpone di Viggianello, Morano Calabro (Cosenza) (UTM WGS84: 33S 595526.4417533), in beech forest, on bark of Fagus sylvatica L., 1630 m, 7 May 2012, leg. J. Malíček, I. Frolov, J. Vondrák, det. J. Malíček (PRA). – Species new to Calabria. Rinodina albana is a temperate crustose species typically found on the bark of deciduous trees with a relatively smooth surface in forests. Its apparent rarity may in part New data on algae, bryophytes, fungi and lichens of Italy 141 reflect difficulties in identification, as it is frequently confused with similar taxa; however, it is probably more widespread in Italy than currently documented (Nimis 2025). J. Malíček, S. Ravera Scoliciosporum pruinosum (P. James) Vězda (Scoliciosporaceae) + TOS: Murlo, Valle del Crevole (Siena), in a humid mixed oak forest near Crevole river (UTM WGS84: 692288.4783840), on bark of Quercus sp., 270 m, 22 March 2025, leg. L. Paoli, det. Z. Fačkovcová (SAV0021202). – Species new to Toscana. Scoliciosporum pruinosum generally grows on bark (especially of old oaks), with optimum in humid deciduous forests of environments with very low eutrophication (often along rivers), such as in the study site. So far there are only few records in Italy, where it is included in the Italian Red List of epiphytic lichens as “Endangered” (Nascimbene et al. 2013). L. Paoli, Z. Fačkovcová Synalissa ramulosa (Bernh.) Fr. (Lichinaceae) + BAS: Monte Castello, San Fele (Potenza) (UTM WGS84: 33T 545540.4519034), on damp limestone rocks, 880 m, 14 April 2025, G. Potenza, D. Puntillo, M. Puntillo, L. Rosati (HLUC 1106). – Species new to Basilicata. Synalissa ramulosa is a mainly southern species in Europe, found on steeply inclined faces of calcareous rocks with periodical water seepage, often overgrowing the thalli of Romjularia lurida (Ach.) Timdal, with a wide altitudinal range but with optimum at relatively low elevations (Nimis 2025). G. Potenza, D. Puntillo, L. Rosati Toninia plumbina (Anzi) Hafellner & Timdal (Ramalinaceae) + SIC: Rocca Busambra S of Marineo, N-exposed slopes in Bosco della Ficuzza (Palermo) (UTM WGS84: 33S 357545.4191641), 1000–1100 m, Quercus - Fraxinus ornus forest, on bark of Quercus spec., on thallus of Pectenia plumbea (Lightf.) P.M.Jørg., L.Lindblom, Wedin & S.Ekman, 1 June 1988, J. Hafellner (with J. Poelt and P.L. Nimis) (no. 85081 GZU) (label text in German). – Species new to Sicilia. The lichenicolous species is lecto-typified on an Anzi collection stored in UPS (Timdal 1992), without locality data but according to the protologue (Anzi 1862) originating from Tuscany. Together with its main host Pectenia plumbea (Lightf.) P.M.Jørg., L.Lindblom, Wedin & S.Ekman, Toninia plumbina has a temperate-Atlantic to humid-Mediterranean distribution. Further isolated populations are known along the eastern coast of the Adriatic Sea (Slovenia, Bosnia and Herzegovina, Montenegro), continuing to the south in the eastern Mediterranean and with a further enclave in the Caucasus (S Russia). The records in this part of the Mediterranean area appear to be concentrated around the Tyrrhenian Sea, both in the mainland and on the delimiting islands in the west, Corsica (Hafellner 1994b) and Sardegna (Baglietto Sonia Ravera / Italian Botanist 20: 125–148 (2025) 142 1879; Nimis and Poelt 1987). Toninia plumbina is included in the Italian Red List of epiphytic lichens and is classified as “Near-Threatened” (Nascimbene et al. 2013). J. Hafellner, P.L. Nimis Trapelia coarctata (Sm.) M. Choisy (Trapeliaceae) + ABR: Monti della Laga, Rocca Santa Maria (Teramo) (UTM WGS84: 33T 369461.4724812), on a sandstone pebble near the soil in a forest dominated by Abies alba Mill., 1485 m, 7 April 2024, leg. M. Di Donatantonio, B. De Ruvo, det. P.L. Nimis (TSB 45826). – Species new to Abruzzo. This species is a Holarctic early coloniser of siliceous pebbles near the soil surface, sometimes also found on bare clayey soil, with a wide altitudinal and altitudinal range. In Italy it is most frequent in upland areas, becoming rare, and mostly Tyrrhenian, in the eu-Mediterranean belt. This record is a nice example of Citizen Science: a photo of the sample, posted by B. De Ruvo (Teramo) on his Facebook page, was accidentally seen by P. L. Nimis, who asked for a sample in order to confirm the identification. M. Di Donatantonio, S. Dose, P. L.
