Distribution: N - TAA (Nimis & al. 2018)

Description: Thallus crustose, episubstratic, forming a soft, gelatinous (when wet), green to grey-green film made of minute granules consisting of clumps of algal cells incompletely surrounded by hyphae. Basidiocarps not lichenized, ephemeral, simple, lobed or branched to sublacerate, 10-25 mm tall, geotropically oriented, often subspathulate or laterally compressed at apex, straw-coloured to pinkish, usually with a small, cap-like white spot at apex (best visible in the dry state), the hymenium extending over c. the upper two thirds. Basidia clavate, bearing a basal clamp, with 4-6 short sterigmata. Basidiospores 1-celled, hyaline, elongate-ovoid to cylindrical, smooth, thin-walled, 5-8.5 x 2-3.5 μm, with a small eccentric apiculus, I-. Photobiont chlorococcoid. Spot tests: all negative. Chemistry: thallus without lichen substances.

Note: a terricolous species with yellowish, straw-coloured to pinkish carpophores which are often subspathulate or laterally compressed toward the apex, and 4-6-sterigmate basidia; widespread in the Holarctic region, but most common in the boreal zone; in the Alps at higher elevations, with a still insufficiently known distribution.
