Lecania nylanderiana A. Massal.
Sched. Crit., 8: 152, 1856.
Synonyms: Lecania athroocarpa Trevis.; Lecania odora Bagl. & Carestia?; Lecanora athroocarpa Nyl.
Description: Thallus crustose, episubstratic, thin, of sharply angular, flat areoles, whitish, pale grey to grey-brown, without a distinct prothallus. Apothecia lecanorine, 0.3-0.8 mm across, usually crowded and often deformed by mutual compression, with a dark brown to black, but always whitish pruinose, flat to slightly convex disc and a grey-pruinose thalline margin. Thalline exciple clearly lecanorine, best developed in basal parts, the cortex with a network of narrow hyphae, the medulla rich in algae; proper exciple thin to moderately thick, pale to dark brown in outer part, paler within; epithecium patchily dark brown, with an epipsamma; hymenium colourless or yellowish in upper part, 60-80 µm high; paraphyses coherent, the apical cells swollen, up to 6 µm wide. Asci 8-spored, narrowly clavate, with a K/I+ blue tholus and a central non-amyloid area, Bacidia-type. Ascospores 3-septate, hyaline, ellipsoid with rounded ends, 12-16(-18) x 4-5 µm, thin-walled, without a gelatinous perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
