Hymenophore annual, cretaceous, adherent, effused forming linear areas to 10 x 3 cm, frequently with a few linear outlying islands; hymenial surface cream, sometimes becoming pallid buff, deeply and finely areolately creviced; margin thinning out, white, adherent, arachnoid or with stout, brief rhizomorphs which may also develop towards the centre. Context white, 200-300 µm thick, sometimes 500-600 µm when vaguely layered, basal layer narrow, of parallel compact hyphae, intermediate layer of erect hyphae embedding masses of crystals and mucilage granules; generative hyphae 4-6 µm diameter, commonly 3.5-4 µm, walls 0.5-1 µm thick, encrusted, with clamp connections. Hymenial layer to 40 µm deep, a dense palisade of basidia, paraphyses and paraphysate hyphae. Basidia subclavate, 12-24 x 4-6 µm bearing 4 spores; sterigmata slender, to 5 µm long. Paraphyses subclavate, 12-18 x 4-5 µm. Paraphysate hyphae cylindrical with rounded apices, projecting to 15 µm, occasionally encrusted at or near apices. Spores elliptical, a few suballantoid, 6-8 x 3-4 µm, walls smooth, hyaline, 0.25 µm thick.

DISTRIBUTION: North America, West Indies, South Africa, Australia, New Zealand.

HABITAT: Effused on bark or decorticated dead branches and stems.

Collections agree with the type in Kew herbarium, ex "South Carolina, No. 2473" save that paraphysate hyphae are usually more strongly developed. Occasional paraphysate hyphae are crystal encrusted either at apices or crystals are arranged in a band beneath the naked apices. The species might therefore be regarded as a Peniophora, but without justification since crystals are accidental, being present on or absent from hyphae in different sections from the same specimen. In the context, crystals are copiously developed and give to sections a chalky appearance. Several collections exhibit rhizomorphs which at first are peripheral but later may become covered by the developing hymenium. Specimens are often sterile, especially if large. The species resembles C. corniculatum in many macrofeatures, but may be separated by the narrower elliptical spores and cylindrical paraphysate hyphae.

TYPE LOCALITY: South Carolina, U.S.A.
