Lecania aipospila  

Thallus usually forming extensive, coalescing patches, pale to dark grey, sometimes brownish or purplish, weakly effigurate, areolate and verrucose, warty and often with contiguous coarse knobbly papillae, warts >1 mm wide, often somewhat lobed at the margin. Upper surface matt to somewhat shining, upper cortex paraplectenchymatous. Prothallus pale.
Anamorph: conidiomata pycnidia, numerous, immersed, 75–250 µm diam., brown-black near the ostiole. Conidia 18-24 x ca 0.8 µm, filiform, slightly to strongly curved.
Teleomorph: ascomata apothecia, usually frequent, 0.5-1 mm diam., somewhat immersed to sessile, apical on the warts or papillae, hence appearing long stalked. Disc red-brown to brown-black, red-brown when wet, concave to weakly convex, not pruinose. Thalline margin concolorous with the thallus, becoming excluded, the outer edge anatomically distinctive, similar to cortex of the papillae, with a hyaline amorphous layer above a single outer layer of isodiametric cells with brown-pigmented, thickened walls, within composed of compact, short-celled, somewhat radiating pseudoparenchyma intermixed with photobiont cells. Hymenium 65–90 µm high. Epithecium brown, red-brown to orange, without granules. Interascal tissue of paraphyses, slightly swollen and short-celled towards the apices, sometimes almost sub-moniliform. Asci cylindric-clavate to clavate, 8-spored. Ascospores 9–14 (–16) x4–6 µm, cylindrical to ellipsoidal, (0–) 1-septate, slightly constricted at the septum, hyaline, smooth and thin-walled, without an epispore, gelatinous sheath or appendages.
Chemistry: may contain two unidentified terpenes.
