Variospora chanousiae (Sambo) ined.
provisionally placed here, ICN Art. 36.1b. Basionym: Caloplaca chanousiae Sambo - Ann. Lab. Chanousia, 1: 34, 1932.
Synonyms: Fulgensia chanousiae (Sambo) Poelt; Gyalolechia chanousiae (Sambo) Cl. Roux
Description: Thallus crustose-placodioid, episubstratic, closely adhering to the rock, ochraceous yellow to brownish orange, epruinose, forming orbicular to usually irregular, up to 5 cm wide rosettes. Central part of thallus verrucose-areolate; marginal lobes dichotomously branched, much longer than wide, markedly convex and sometimes almost subcylindrical, straight to usually sinuous, divergent, 0.3-0.8(-1.5) mm wide, to 0.6 mm thick. Cortex paraplechtenchymatous, the cells with broad, rounded to oval lumina and thin, strongly gelatinized walls. Apothecia 1-1.5(-2) mm across, rounded to irregular in outline, slightly constricted at base, with a flat to slightly convex, orange-brown disc, a thin proper margin, and a thick, smooth to crenulate thalline margin. Proper exciple of radiating hyphae, the cells with broadly oval to oblong lumina; epithecium orange-brown, K+ purple-red; hymenium colourless, 80-100 µm high; hypothecium colourless. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 1-septate (very rarely 2-septate), not polarilocular and not constricted at septum, hyaline, fusiform, (15-)17-24(-28) x (3-)3.5-6 µm, straight or slightly curved. Pycnidia orange, multi-chambered. Conidia pyriform. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-red, C-, KC-, P-. Chemistry: thallus and apothecia with unidentified anthraquinones.
