Bibl. Lichenol., 18: 156, 1983. Basionym: Lecidea tuberculosa Fée - Essai Crypt. Exot.: 107, 1825 (1824)
Synonyms: Bacidia pachycarpa (Delise ex Duby) Trevis.; Bacidia tuberculosa (Fée) Trevis.; Bombyliospora pachycarpa (Delise ex Duby) A. Massal.; Megalospora pachycarpa (Duby) H. Olivier
Distribution: N - Frl. C - Tosc.
Description: Thallus crustose to subleprose, episubstratic, up to 0.2 mm thick, dull, yellowish white, pale grey-green or grey-white, sorediate, forming large patches, without a distinct prothallus or with athin dark prothallus. Soralia at first more or less discrete, but soon becoming confluent, forming a more or less continuous sorediate crust; soredia fine to coarse, usually aggregated into up to 80 µm wide consoredia, often with needle-like projecting crystals. Apothecia very rare, rounded, (0.5-)1-2 mm across, with a concave to flat, dark brown disc and a paler or concolorous, raised, persistent proper margin. Proper exciple of radiating hyphae, compact and brown in outer part, loose-arachnoid and more or less colourless within; epithecium orange-brown, densely inspersed with granules not dissolving in K; hymenium colourless, 130-180 μm high, inspersed with oil droplets; paraphyses sparingly branched and anastomosing, slightly swollen at tips; hypothecium yellowish brown to brown. Asci 1-spored, clavate-subcylindrical, with a thick amyloid tholus and a I+ blue gelatinous outer layer. Ascospores (3-)5-11-septate, hyaline, 70-160 x 25-35 µm, the wall c. 2 μm thick. Conidia short-bacilliform. Photobiont chlorococcoid (Symbiochloris), the cells 5-14 μm wide. Spot tests: thallus: K+ pale yellow, C-, KC+ yellow, P- or P+ faintly yellow, UV-. Chemistry: usnic acid, zeorin, unknown terpenoids.Note: a mainly pantropical species found on old deciduous (mainly Fagus) and coniferous (mainly Abies) trees in humid montane forests, sometimes overgrowing epiphytic bryophytes. It is included in the Italian red list of epiphytic lichens as “Critically Endangered” (Nascimbene & al. 2013c).
