Protomicarea limosa (Ach.) Hafellner

in Hafellner & Türk, Stapfia, 76: 156, 2001. Basionym: Lecidea limosa Ach. - Lichenogr. Univ.: 182, 1810.

Synonyms: Lecidea borealis (Körb.) Anzi; Lecidea ementiens Nyl.; Lecidella borealis Körb.

Distribution: N - Frl (Tretiach & Hafellner 2000), Ven, TAA (Caniglia & al. 2002, Nascimbene & al. 2022), Lomb (Dalle Vedove & al. 2004), Piem (Isocrono & al. 2004), VA (Piervittori & Isocrono 1997, 1999), Emil (Dalle Vedove & al. 2002, Fariselli & al. 2020).

Description: Thallus crustose, episubstratic, subgelatinous when wet, whitish grey to grey, granulose to small-areolate, the areoles mostly small, 0.2-0.6 mm wide, but sometimes becoming verrucose and up to 1 mm wide, contiguous, forming a more or less compact crust, sometimes with a white prothallus. Apothecia biatorine, black, round, sessile, (0.4-)0.5-0.8(-1) mm across, with a strongly convex disc, without a proper margin. Epithecium deep bluish green, the colour often extending down into the upper part of the hymenium, of radially arranged hyphae, K-; hymenium 45-65 μm high, at least partially green in upper part, I+ red; paraphyses coherent, mostly simple, 1.2-2 μm thick, scarcely thickened at apex; hypothecium patchily reddish brown, K+ brownish-orange. Asci 8-spored, cylindrical-clavate, the I+ blue tholus with a wide, I+ dark blue tube structure that expands towards the top, without a pale axial body, Psora-type. Ascospores 1-celled, hyaline, narrowly ellipsoid to fusiform, (8-)10-14(-15) x 3-4.5(-5) μm. Conidia bacilliform, 6-7 x c. 1.5 μm. Photobiont chlorococcoid, the cells 7-12 μm wide. Spot tests: thallus K-, C-, KC-, P+ orange-red. Chemistry: pannarin and triterpenoids.

Note: an arctic-alpine to boreal-montane, circumpolar lichen found on naked soil in sites with a long snow-covering period, in clearings of Alpine grasslands, more rarely on moribund bryophytes and plant debris: in the Alps it can reach the nival belt.
