Hymenophore annual, membranous, adherent, effused, forming linear areas to 12 x 3 cm; hymenial surface cream, pruinose, deeply areolately creviced; margin thinning out, arachnoid, white, adherent. Context white, 80-150 µm thick, basal layer of a few repent hyphae, intermediate layer of densely arranged mainly erect hyphae among which, at the base, are few or many thick-walled hyphae; generative hyphae 2.5-4 µmdiameter, walls 0.5 µm thick, naked, with clamp connections. Cystidia arising from the basal layer and projecting to 65 µm, naked, cylindrical, 65-144 x 8-12 µm, lumena capillary, apices thin-walled and rounded. Hymenial layer to 25 µm, deep, a close palisade of basidia, paraphyses, and cystidia. Basidia subclavate, 12-16 x 4-5 µm, bearing 4 spores; sterigmata erect, slender, to 8 µm long. Paraphyses subclavate, 6-10 x 3.5-4 µm. Spores cylindrical or allantoid, with rounded ends, 6-8 x 1.5-2 µm, walls smooth, hyaline, 0.1 µm thick.

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

HABITAT: Effused on bark or decorticated wood of dead branches.

Cystidia are cylindrical, with walls so thickened, save at apices, that lumena are capillary. Apices remain thin-walled, so that cystidia simulate inverted miniature thermometers. Cystidia arise in the context as deeply staining, thin-walled organs, resembling gloeocystidia. Shortly their walls become thickened from within until lumena are almost obliterated. Spores are similar in shape to those of T. subalutacea, but smaller. The intermediate tissue consists mainly of erect sparsely branched hyphae with, near the base, intertwined convoluted thick-walled hyphae of the same diameter. The latter are extensions of basal roots of the cystidia, may be abundant or scanty, and sometimes occupy one-third of the base of the context. As the name Peniophora glebulosa (Fr. ex Bres.) Sacc. & Syd. cannot be employed for the species, being a nomen confusum, Rogers & Jackson applied to the cystidiate species of the complex, with a validating description, the herbarium name used by Ellis & Everhart.
