Lecidea leprarioides Tønsberg

Sommerfeltia, 14: 173, 1992.

Synonyms: Lecidea turgidula Fr. var. pulveracea Th. Fr.

Distribution: N - TAA (Nascimbene & al. 2009, 2010, 2022, Nimis & al. 2015).

Description: Thallus crustose, endosubstratic in non-sorediate parts to thinly episubstratic, greyish white to greenish grey, rarely with a pale brown tinge, forming irregular patches up to several dm across, usually sorediate, without a distinct prothallus. Soralia at first scattered and irregular, but soon confluent and forming a discontinuous subleprose crust, the soredia farinose, 10-30 μm in diam. Apothecia biatorine, sessile and constricted at base, 0.3-0.6(-1) mm across, sometimes tuberculate, with a grey to black, often bluish-pruinose, convex disc and a very thin, soon excluded proper margin. Exciple blue-green near the hymenium, colourless to brown in lower part, of branched and anastomosing, radially arranged hyphae, the pigmented parts N+ violet; epithecium greenish to blue-green, inspersed with ochraceous, 5-10 μm thick granules, N+ violet; hymenium colourless to pale green, 25-40 μm high; paraphyses up to 1 μm thick at base, moderately branched and anastomosing, hardly swollen at tips; hypothecium pale yellow to reddish brown. Asci 8-spored, clavate, Bacidia-type. Ascospores 1-celled, hyaline, narrowly ellipsoid, straight or slightly curved, 7-11.5 x 2.5-3.5(-4) µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: pseudoplacodiolic acid.

Note: a rare, mainly boreal species of acid bark in upland areas, closely related to L. turgidula (Schmull & al. 2011).

Growth form: Crustose

Substrata: bark

Photobiont: green algae other than Trentepohlia
