Distribution:

Description: Thallus crustose, thinly episubstratic, consisting of dark green, subglobose goniocysts, the wall smooth or covered in shallow, to 2 μm tall papillae. Apothecia short-lived, 0.2-0.4 mm across, without a proper margin, scattered or confluent in clusters of 2-3, convex and appressed, rarely shortly turbinate when young, grey-white to pink-brown, matt, sometimes finely tomentose (microscope!). Proper exciple absent; hymenium lacking gelatine, consisting of asci and strongly branched, sparse paraphyses which rarely reach the surface of the hymenium; hypothecium absent. Asci 8-spored, cylindrical, thick-walled, with a thick I+ blue apex (except for an apical pore). Ascospores 7-11-septate, hyaline, thread-like, 60-85 x 2-2.5 μm, the lower end tapered to a narrow point. Photobiont chlorococcoid (Leptosira). Spot tests: all negative. Chemistry: without lichen substances.

Note: on soil, moribund bryophytes and algal films over siliceous substrata in sheltered, moist situations, often also on metal-contaminated ground. Most frequent, but generally rare, in Western Europe. To be looked for in Italy.

Growth form: Crustose

Substrata: soil, terricolous mosses, and plant debris

Photobiont: green algae other than Trentepohlia
