in Roux & al., Bull. Soc. linn. Provence, 60: 172, 2009. Basionym: Verrucaria zamenhofiana Clauzade & Cl. Roux - Bull. Soc. Bot. Centre-Ouest, n. sér., nr. spéc. 7: 823, 1985.
Synonyms: Dermatocarpon compactum sensu Clauzade & Rondon
Description: Thallus crustose, areolate-subsquamulose, dark brown to almost black, 0.2-0.7 mm thick, parasitic on Staurothele areolata. Areoles 0.6-1.5 mm wide, finely crenulate-lobulate, crowded and fitting together like a puzzle, or with slightly overlapping margins, smooth and slightly glossy. Upper cortex well delimited, 20-25 µm thick, the uppermost cell layer with brown pigment, sometimes overlain by a very thin epinecral layer; medulla subparaplectenchymatous; lower cortex limited to the marginal part of areoles, 20-40 µm thick, paraplectenchymatous, pale brown, with granular inspersions, below with colourless, 3-4.5 µm thick rhizohyphae. Perithecia totally immersed; exciple subglobose, 0.18-0.3 mm across, the exciple colourless; involucrellum lacking; paraphyses absent, substituted by simple periphyses; hymenial gel hemiamyloid. Asci 8-spored, clavate, I-, fissitunicate, the wall thickened above, Verrucaria-type. Ascospores 1-celled, hyaline, broadly ellipsoid to subglobose, 10-12 x 9-10 µm. Pycnidia immersed, inconspicuous, of the Dermatocarpon-type. Conidia bacilliform, 5-7 µm long. Photobiont chlorococcoid (Myrmecia). Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
