Description: Hymenophore annual, sometimes biennial, membranous, adherent, effused forming irregular
often linear areas 5-15 x 2-6 cm; hymenial surface white, drying cream, even or slightly
tuberculate, often farinose, finally deeply creviced; margin thinning out; sometimes
indefinite, white, fibrillose or arachnoid, adherent. Context white, 80-150 µm thick, basal
layer scanty, of parallel hyphae, intermediate layer of loosely arranged mainly erect scantily
branched hyphae, becoming more dense beneath the hymenium and scantily encrusted;
generative hyphae 3-4 µm diameter, walls 0-2 µm thick, hyaline, with clamp connections.
Metuloids arising from the hymenium and subhymenium, some projecting to 30 µm, sometimes
a few scattered in the intermediate layer, cylindrical, 30-50 x 5-8 µm, apices rounded or as often
slightly capitate, finely or coarsely encrusted, or with the apical region naked. Hymenial layer to
40 µm deep, a loose palisade of basidia, paraphyses, metuloids, and occasional paraphysate
hyphae. Basidia subclavate, 16-22 x 4-5 µm, bearing 4 spores; sterigmata slender, to 5 µm long.
Paraphyses subclavate, 8-16 x 3-4 µm. Paraphysate hyphae scanty, cylindrical, projecting to 15
µm. Spores broadly elliptical, many subglobose, 5-6 x 3.5-4 µm, walls smooth, hyaline, 0.2 µm
thick.
Habitat: HABITAT: Effused on bark or decorticated wood of dead branches.
Distribution: DISTRIBUTION: Europe, Great Britain, North America, Australia, New Zealand.
Notes: Specific features are the abundant, broadly elliptical, small spores, narrow metuloids often
capitate and bearing fine crystals, loosely arranged encrusted context hyphae and white or
cream, fragile hymenophore. In collections from this region metuloids are distinctly
encrusted, whereas in European specimens examined in Kew herbarium, some bore only a
few crystals, and many were naked. Because of this the species has sometimes been treated as
a Corticium, and metuloids described as 'cystidioles'.
