Distribution: N - TAA (Nascimbene & al. 2007, 2022).

Description: Thallus crustose, episubstratic, forming a soft, gelatinous (when wet), green to dark green film made of spherical granules consisting of clumps of algal cells incompletely surrounded by appressed pseudoparenchymatous hyphae. Hyphae and cortical cells of granules more or less thickened, the walls 1-1.5 µm. Clamp connections absent in all hyphae. Basidiocarps not lichenized, with a 0.5-1.5 cm wide, bright yellow to orange-yellow, omphaloid, marginally striate cap, concolorous or slightly paler, decurrent, veined and sometimes forked lamellae, and a 1-1.5 cm high, 1.5-2.5 mm thick stipe which is more or less concolorous with cap, and pubescent throughout. Basidia clavate, mostly with 4 sterigmata (rarely with 1 or 2 sterigmata). Basidiospores 1-celled, hyaline, ellipsoid, 6.5-9.5 x 3.5-4.5 µm, thin-walled. Photobiont chlorococcoid (Coccomyxa). Spot tests: all negative. Chemistry: thallus without lichen substances.

Note: a basidiolichen of acid organic soil, most common around treeline; perhaps more widespread in the Alps but overlooked by lichenologists.
