Distribution:

Description: Thallus squamulose, consisting of pale grey green to olive-green, 0.3-1(-2.5) mm wide squamules with ascending, lobulate, sorediate margins, the soralia labriform to subcapitate, pale grey to grey-green (creamy white in shade-forms), sometimes confluent and covering the whole surface, Apothecia rare, lecideine, up to 1-1.5(-2) mm across, with a brown to dark grey green, at first flat, then convex disc, and a usually paler, finally often excluded proper margin. Epithecium pale yellowish brown; hymenium colourless; paraphyses coherent, slender, branched and anastomosing, only slightly thickened at apex; hypothecium pale yellowish brown. sometimes with brownish, Ascospores 1-celled, hyaline, ellipsoid, 8-11 x 3.5-5.5 μm. Photobiont chlorococcoid. Spot tests: thallus and soredia K-, C-, KC-, P-, UV+ glaucous. Chemistry: an unidentified lichen compound.

Note: a species whose thallus resembles the primary squamules of Cladonia, mostly sterile, found on plant debris and rotting wood. Widespread worldwide, in Central Europe it mostly occurs in montane forests; known from several localities in the Alps, mainly in Austria, elsewhere probably overlooked or confused with other species, being mostly sterile. To be looked for in the Italian Alps.

Growth form: Crustose

Substrata: soil, terricolous mosses, and plant debris

Photobiont: green algae other than Trentepohlia

Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
