Hymenophore annual, arachnoid, closely adherent, effused forming irregular areas to 5 x 3 cm; hymenial surface at first dingy white, becoming grey or bluish-grey, irregularly granular, not creviced; margin thinning out, arachnoid, white, adherent. Context white, 10-100 µm thick, commonly 10-20 µm, basal layer narrow, of densely arranged parallel hyphae, intermediate layer wanting; generative hyphae 3-3.5 µm diameter, walls 0.2 µm thick, sometimes inflated between septa, naked, with clamp connections. Hymenial layer to 30 µm deep, a scanty palisade of basidia and paraphyses. Basidia subclavate or subcylindrical, 8-16 x 4-6 µm, bearing 4 spores; sterigmata slender, to 7 µm long. Paraphyses subclavate, 6-10 x 4-5 µm. Spores globose, subglobose, or obovate, 4.5-5.5 x 4-4.5 µm, walls echinulate, 0.5 µm thick.

DISTRIBUTION: Europe, Great Britain, North America, Australia, New Zealand.

HABITAT: Effused on bark or: decorticated dead wood.

Specific features are the echinulate, subglobose, or obovate spores, small basidia, subclavate or elliptical paraphyses, non-creviced surface which on a dark substratum appears as a delicate grey or bluish-grey arachnoid film, and absence of an intermediate layer. Appreciable variations were noted in specimens examined, particularly in thickness of the context, shape and size of spores, and presence or absence of ampullae on context hyphae. The context is reduced to a basal layer of mainly parallel hyphae, which soon collapse and become pseudoparenchymatous. Spores are.similar in size and echinulations to those of C. sulphureum, differing mainly in shape and finer spines.

TYPE LOCALITY: Germany.
