Felipes leucopellaeus (Ach.) Frisch & G. Thor

in Frisch & al., Taxon, 63: 738, 2014. Basionym: Spiloma melaleucum var. leucopellaeum Ach. - Lichenogr. Univ.: 138, 1810.

Synonyms: Arthonia leucopellaea (Ach.) Almq.; Arthonia marmorata Nyl.; Arthonia melaleuca sensu Malme; Arthonia schaereri A. Massal.; Melaspilea associata Norman; Trachylia leucopellaea (Ach.) Eitner

Distribution: N - Frl. C - Sar (Cossu 2013).

Description: Thallus crustose, white to pale yellowish white, smooth to granulose or arachnoid, sometimes inapparent, the hyphae K/I-. Apothecia 1-2 mm across, irregularly rounded to weakly lobed or star-shaped, sometimes short-lirelliform, with a dark brown to black, but more or less grey-pruinose disc, and a somewhat arachnoid, slightly prominent, whitish marginal zone. Proper exciple dark brown, of densely entangled hyphae, with a marginal layer of hyaline to pale brown, branched and anastomosing hyphae with cylindrical cells; epithecium brown, K+ yellowish green; hymenium colourless to pale yellowish brown, 25-60 μm high; paraphysoids brown-walled, 1-1.5 μm thick in lower part, the apical cells up to 2 μm wide, without a dark cap, the densely intertwined tips often extending horizontally; hypothecium dark brown, 35-70 µm high. Asci 8-spored, broadly clavate, semi-fissitunicate, with a large apical dome and a distinct ocular chamber. Ascospores 3-4-septate, hyaline (but overmature spores often brownish and finely warted), oblong-ovoid, (9-)11-17(-19) x 3-5 µm, with almost equal cells. Photobiont trentepohlioid. Spot tests: thallus K+ pale pale yellow to brownish orange, C-, KC-, P-, UV-. Chemistry: two unknown substances in thallus.

Note: on bark of conifers in old-growth forests under suboceanic climatic conditions; widespread in the temperate to boreal zones of the Holarctic region, in the Alps mainly in the montane belt, but lacking in the central Alps with more continental climate conditions. It is included in the Italian red list of epiphytic lichens as “Critically Endangered” (Nascimbene & al. 2013c).
