Th.Fr., 950 m, 3 September 2002, J. Hafellner (GZU - JH84423). – Species new to Trentino-Alto Adige.

Arthonia parietinaria - restricted to Xanthoria s.str. - is a rather conspicuous species and is fairly common in Europe (Fleischhacker et al. 2016). The earlier records of an Arthonia on Xanthoria parietina (L.) Th.Fr. in Italy, published under various other names, are relatively few and have been sorted by Brackel (2020). In Italy, most of the findings so far origin from the central and southern parts of the country (Nimis and Martellos 2024) but as demonstrated here, the species can also be expected in the valleys of the Alps.

Hebeloma populinum Romagn. (Hymenogastraceae)

+ CAL: Botanical Garden, University of Calabria, Rende (Cosenza) (UTM WGS84: 33S 605816. 4357354), at the edge of a riparian wood among the litter of natural Populus canescens trees (prevailing species), 205 m, 2 December 2022, G. Sicoli, A.B. De Giuseppe, N.G. Passalacqua (CLU F335). – Species new to Calabria.

Sparse basidiomata immediately attributable to the genus Hebeloma (Fr.) P.Kumm. were found in late autumn 2022 on the wet ground among litter and herbaceous plants under the crown of a poplar tree along a narrow stream. The pilei were 2.5–3.0 cm wide, smooth and clearly viscid, pale whitish-argillaceous, with a slightly inrolled margin. The gills were pale and rather dense, initially weeping then brown-spotted. The stipe was whitish to ochraceous, finely floccose. Spores were amygdaloid to citriform, verrucose to echinulate, 11.3–14.7 × 6.7–8.0 µm in size. Cheilocystidia were filiform to clavate, sometimes capitulate. The fungus had a sweetish smell and a bitter taste. So far, H. populinum has been reported in a few administrative regions from northern and central Italy, but not in Calabria (Onofri et al. 2013).

A. Hafellner, J. Hafellner, M. Tretiach, det. J. Hafellner (GZU - JH8736). – Species new to Piemonte.

This sorediate species, not rarely also fertile and then easier to recognize, mostly grows on horizontal to inclined faces of siliceous rock near the ground. It is widely distributed in the Alps (Nimis et al. 2018) but apparently under-collected in wide areas. In Italy it is poorly recorded, being only known from Friuli-Venezia Giulia (Tretiach and Hafellner 2000) and Lombardia (Nascimbene et al. 2021).

Bellemerea alpina (Sommerf.) Clauzade & Cl.Roux (Lecideaceae)

+ VEN: Viel del Pan, Pordoi (Belluno), on siliceous volcanic rock (UTM WGS84: 32T 716833.5150861), 2492 m, 8 August 2024, J. Nascimbene (BOLO). – Species new to Veneto.

Bellemerea alpina is an arctic-alpine, silicicolous, crustose lichen that is quite widespread in the Italian Alps (Nimis et al. 2018; Nimis and Martellos 2024) up to the northern Apennines (Ravera et al. 2024b). The only record reported from Veneto by Nimis (1993) is likely due to a misinterpretation by Jatta (1909–1911), since no citations of the species are reported by Massalongo (1852; Nimis, in litt.).

Cladonia ciliata Stirt. (Cladoniaceae)

- LAZ. – Species to be excluded from the flora of Lazio.

Cladonia ciliata is an oceanic species (Litterski and Ahti 2004) commonly found on soil with moss in undisturbed maquis vegetation, particularly in humid coastal regions. In Italy, its presence is limited to a few locations, mainly along the Tyrrhenian coast (Nimis 2024). Although it is listed as Endangered (EN) on the national Red List (Nascimbene et al. 2013), recent observations indicate a positive trend for this species in Toscana (Ravera et al. 2024a). The only record of this species in Lazio is the herbarium specimen TSB 17703, collected at the Etruscan necropolis of Blera (Viterbo) (Nimis and Martellos 2024). Recent surveys (August 2024) at the same collecting site have confirmed the disappearance of the species, likely due to neglect and abandonment of the archaeological area, as well as the gradual encroachment of the Mediterranean macchia at the expense of lichen populations.

Hypotrachyna sinuosa (Sm.) Hale (Parmeliaceae)

+ PIE: Val Vigezzo, Craveggia (Verbano-Cusio-Ossola) (UTM WGS84: 32T 464206.5116235), on bark of Betula sp., 1030 m, 12 June 2024, Ph. Clerc (G). – Species confirmed for Piemonte.

According to Nimis (2024), H. sinuosa is a widespread, but rare mild-temperate species found on bark and epiphytic mosses in open, humid and cold forests. It is declining throughout Italy and presently almost extinct. Hypotrachyna sinuosa is easily distinguished in the field from the other Italian Hypotrachyna species by its small size, the farinose soralia covering apices of ± ascending lobes and its yellow-green thallus (usnic acid). It was found in an alluvial alder grove near the Swiss border. A few other thalli could be observed in a small area, all on Alnus incana (L.) Moench. The most recent records of this species in Piemonte date back to the late 1800s (Baglietto and Carestia 1865, 1880).

Maronea constans (Nyl.) Hepp (Fuscideaceae)

+ PIE: Val Vigezzo, Craveggia (Verbano-Cusio-Ossola) (UTM WGS84: 32T 464335.5116267), on bark of Alnus incana (L.) Moench, 1075 m, 16 April 2024, Ph. Blaise (G). – Species new to Piemonte.

Maronea constans is a rare mild-temperate lichen found on smooth bark, which was probably more frequent in the past (Nimis 2024). According to Scheidegger et al. (2002) it is near extinction in most Alpine countries, and it is included in the Italian Red List of epiphytic lichens as Critically Endangered (Nascimbene et al. 2013). However, its superficial resemblance to Rinodina may contribute to its not being collected and recognized. The present sample was found in an alluvial alder grove near the Swiss border. Interestingly, numerous thalli could be observed (several dozens) in a small area, all on Alnus incana (L.) Moench.

Hafellner, P.L. Nimis, M. Tretiach (GZU - JH87264). – Species new to Liguria.

The species has a wide, circumpolar arctic-alpine distribution in the northern hemisphere. In the Alps, it appears to be fairly common over calcareous substrates from the tree line to the nival belt (Nimis et al. 2018). In Italy it has so far been recorded only from the northern and central parts of the country (Nimis and Martellos 2024).

Hafellner , P. L. Nimis, M. Tretiach (GZU - JH87513). – Species new to Piemonte.

This Palearctic, montane to alpine species is widely distributed in central and southern Europe including the Alps (Nimis et al. 2018). In Italy, it is known from the Alps to Calabria (Nimis and Martellos 2024) but is not common due to the narrow ecological niche, viz. subvertical to overhanging faces of limestone cliffs.

J. Malíček, I. Frolov, J. Vondrák, det. J. Malíček (PRA). – Species new to Italy (Calabria).

This species is primarily found in western parts of Europe, growing on acidic rocks beneath overhangs where it remains consistently shaded from direct sunlight. It often occurs in old, established woodlands and it has been recorded in various locations, including the Eastern Alps (Nimis et al. 2018), but its almost constant sterility suggests that it may be underreported or overlooked in other areas.

Solenopsora liparina is a saxicolous species characterized by a crustose-placodioid thallus of olivaceous grey or grey-green colour, which can form up to 2.5-cm wide rosettes or arcs of lobes. Lobes are flat to slightly convex, 0.3–0.6 mm wide, with white pruina at the margin. It grows on ultramafic rocks with a very low silica content, such as serpentinite (Guttová and Nimis 2021). So far, scattered localities are known from the Balkan peninsulas, Turkey, Czech Republic, France, and British Isles (Guttová et al. 2019). In Italy, it was recorded only from few sites in Liguria, Lombardia, and the Apennines in Toscana (Nimis and Martellos 2024). At the locality of Monte Prinzera, it predominantly grows on west and southwest-facing rocks and in rock fissures.

+ VDA: Piccolo San Bernardo pass (Aosta) (UTM WGS84: 32T 336331.5062336), on pebbles and on soil among rocks, in alpine pastures, 2065 m, 23 August 2024, S. Ongaro, D. Isocrono (ORO n. 334). – Species new to Val d’Aosta.

Trapelia glebulosa is distinguished by its small scattered squamules bearing apothecia at a very early stage. This species usually grows near the ground, mainly in upland areas such as the one in Val d’Aosta. Although T. glebulosa is common throughout the Alps (Nimis et al. 2018), it had not yet been reported for Val d’Aosta, a region that has been extensively studied. Since the species is often infertile, it may be overlooked or ignored or mistaken for small morphotypes of T. coarctata (Sm.) M. Choisy.

Zwackhia viridis (Ach.) Poetsch & Schied. (Lecanographaceae)

+ PIE: Maritime Alps, Valle Vermenagna, Robilante, Orrido delle Barme (Cuneo) (UTM WGS84: 32T 380106.490502), on oak twigs in woodlands, 820 m, 25 May 2024, D. Isocrono (ORO n. 395). – Species new to Piemonte.

A crustose, photophobic lichen characterized by a thin thallus with numerous, regularly distributed lirellae. The absence of soralia distinguishes this species from the similar Z. sorediifera (P.James) Ertz. In Italy, it has been reported more frequently in the Tyrrhenian than in the Adriatic side of the peninsula (Nimis 2024). This species is widespread throughout the Alps, although it is not very common (Nimis et al. 2018).
