Apothecia adnate, convex, becoming immarginate, black, bare, scabrid; exciple radiate, pale exteriorly, red-brown interiorly; hypothecium red-brown; epihymenium blackish green; hymenium 30 μm, 1+ blue turning violet; paraphyses 1.5 μm, tips thick and black; spores ovoid to oblong, 11-16 x 4-6 μm.
This species grows over moss and humus. It is very rare, being reported from St. Lawrence Bay. Kamtchatka. and Port Clarence, Alaska. It is possibly a member of the amphi-Behringian element in the flora. It is very close, however, to Catillaria sphaeralis Korber. but differs in the dark color of the hypothecium.
