Lecidea nylanderi (Anzi) Th. Fr.

Lichenogr. Scand., 1, 2: 462, 1874. Basionym: Biatora nylanderi Anzi - Cat. Lich. Sondr.: 75, 1860.
Synonyms: Lecidea leprodea Nyl.
Distribution: N - Ven (Caniglia & al. 1999), TAA (Nascimbene & al. 2007b, 2014, Nascimbene 2014), Lomb.
Description: Thallus crustose, endosubstratic to episubstratic, to several dm in diameter, sorediate, often delimited by a bluish prothallus. Esorediate areoles bluish grey, often indistinct or absent, up to 0.2 mm in diam., irregular to rounded in outline, convex, soon bursting apically into discrete soralia which finally may become confluent, forming a subleprose crust. Soredia bluish grey (greenish or whitish in shaded situations), sometimes tinged brown, farinose, sometimes gathered in 20-60 μm wide consoredia. Apothecia rare, lecideine, rounded to deformed, to 0.2-0.8(-1) mm across, with a reddish brown to blackish brown, flat to slightly convex disc, and a thin, paler brown, finally often excluded margin. Proper exciple pale brown in section, of radiating hyphae; epithecium orange brown, inspersed with granules; hymenium colourless, c. 50 µm high; paraphyses coherent, simple or weakly branched and anastomosing, 0.7-1 µm thick at base, the apical cells swollen and 2.5-4 µm wide; hypothecium colourless. Asci 8-spored, clavate, Bacidia-type. Ascospores 1-celled, hyaline, globose, 5-7.5 µm wide. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV+ white. Chemistry: divaricatic acid.
Note: a probably circumboreal-montane lichen found on the bark old conifers inside forests, much more rarely on lignum, usually in upland areas. The species, related to Myochroidea leprosula (Printzen 1995), does not belong to Lecidea s.str.: Schmull & al. (2011) presented a phylogenetic tree where it is placed within the Lecanoraceae.
Growth form: Crustose
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
