Lecidea albofuscescens Nyl.

Flora, 50: 370, 1867.
Synonyms: Biatora albofuscescens (Nyl.) Arnold; Lecidea dolera Nyl.
Distribution: N - Ven, TAA (Thor & Nascimbene 2007, Nascimbene & al. 2007b, Nimis & al. 2015).
Description: Thallus crustose, episubstratic, usually thin, continuous and smooth to finely verruculose, mostly whitish. Apothecia lecideine, 0.3-0.6 mm across, dark brown to blackish brown, appressed, with a flat to finally convex disc, and a thin, usually persistent but often finally excluded proper margin. Proper exciple colourless in outer part, brown-black to dark red-brown within; epithecium brown; hymenium colourless; paraphyses coherent; hypothecium brown-black to dark red-brown, without blue-violet granules. Asci 8-spored, narrowly clavate. Ascospores 1-celled, hyaline, ellipsoid, 9-12 x 4-5 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-. Chemistry: not known, probably without lichen substances.
