Pilei annual, scattered, membranous, waxy, fragile, 0.1-0.5 mm. diameter, attached by a brief stem-like base, at first subglobose becoming urceolate or discoid; exterior dingy white, covered with a scanty tomentum, hairs 4-6 µ diameter, wall 0-5 µ thick, hyaline, finely crystal coated; margin inturned, fimbriate; hymenial surface slightly concave, white or cream. Context white, to 80 µ thick, to 250 µ at the base, of radiately arranged mainly parallel hyphae; generative hyphae 5-6 µ diameter, wall 0.25 µ thick, branched, septate, hyaline. Hymenial layer to 80 µ deep, paraphyses filiform, somewhat scanty, apices acuminate. Basidia clavate, some almost capitate, 60-80 x 16-20 µ, 4-spored. Spores turbinate, 14-16 x 10-12 µ, smooth, hyaline.

DISTRIBUTION. New Zealand.

HABITAT. Scattered on bark of dead twigs.

Pilei sparsi, cerosi, primo subglobosi, deinde urceolati vel discoides, 0.1-0.5 mm. diam.; exteriore parte sordide alba, tomento tenui tecta, pilis 4-6 µ diam., subtiliter crystallis illinatis, pariete 0.5 µ crasso; margine inflecto, fimbriato. Contextus albus ad 80 µ crassus, hyphis ad 6 µ diam., in radiis ordinatis, pariete 0.25 µ crasso. Paraphyses filiformes, apicibus acuminatis. Sporae turbinatae, apiculatae, 14-16 x 10-12 µ, leves, hyalinae.

Separated from C. villosa by the small size of the pilei, rather scanty tomentum, large. almost capitate basidia and turbinate spores. The latter show a general resemblance to those of C. pyriforma, differing in shape and smaller size.
