Description: 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.
Habitat: HABITAT: Effused on bark or decorticated dead branches.
Distribution: DISTRIBUTION: Europe, Great Britain,
North and South America, Australia, Tasmania, New Zealand.
Notes: 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.
