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
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, weakly amyloid; paraphysoids strongly coherent, 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, lacking hemiamyloid tholus structures. Ascospores 3-4-septate, hyaline (but overmature spores often brownish and finely warted), oblong-ovoid, widest above the middle, (9-)11-17(-19) x 3-5.5 µm, with subequal cells. Photobiont trentepohlioid, the cells thick-walled, 15-40 x 8-30 μm. Spot tests: thallus K+ pale pale yellow to brownish orange, C-, KC-, P- or P+ orange, UV-. Chemistry: two unknown substances in thallus.
