Hymenophore annual, coriaceous, adherent, effused forming linear areas to 20 x 3 cm; hymenial surface at first dingy white, becoming alutaceous, buff, bluish-grey or reddish-brown, pelliculose, even or finally sparsely creviced; margin thinning out, membranous, vernicose, cream, adherent. Context white, finally reddish-brown and glistening in section, 100-250 µm thick, basal layer stout, of densely compacted parallel hyphae, intermediate layer of closely compacted erect hyphae often encrusted with brown mucilage granules; generative hyphae 3.5-4 µm diameter, walls 0.25-0.5 µm thick, with clamp connections. Hymenial layer to 40 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 24-35 x 4-6 µm, bearing 2-4 spores; sterigmata slender, to 6 µm long. Paraphyses subclavate, 12-22 x 3-5 µm. Spores broadly elliptical, some apiculate, 6-8 x 3-4 µm, walls smooth, hyaline, 0.2 µm thick.

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

HABITAT: Effused on bark or decorticated dead branches.

Collections listed agree with European specimens examined in Kew herbarium, differing in the slightly larger spores and more vivid colours of the surface. At first plants are pelliculose, alutaceous, waxy, and adherent; in more mature specimens they appear pruinose, livid, or reddish-brown, and often plum colour where fertile. Context tissues are encrusted with mucilage granules and interstices filled with them so that sections appear reddish-brown and glistening. In old specimens the surface may be creviced, though sparingly. The basal layer is normally thick, occupying about half the context; in several collections it is thin, or tissues may be zoned with two or three narrow bands of parallel hyphae and erect intermediate hyphae alternating. Occasional plants display a few paraphysate hyphae with apices bearing from one to three short branches. Bridging hyphae are not uncommon. From C. leptospermi and C. vitellinum the species may be separated by the larger basidia, context hyphae of greater diameter, larger spores, and different structure of the context.

TYPE LOCALITY: Europe.
