Description: Hymenophore annual, arachnoid,
adherent, effused forming small irregular areas to 8 x 3 cm; hymenial surface
sulphur yellow or chrome, farinose, not creviced; margin thinning out,
arachnoid, concolorous, adherent, sometimes rhizomorphic. Context yellow, either
composed of rhizomorphic strands each formed from 2-6 cemented hyphae with a
loose weft of solitary hyphae between, forming a scanty reticulated tissue to 30
µm deep; or of an intermediate layer of mainly erect hyphae arising from a
narrow basal layer of a few repent hyphae and embedding numerous spores;
generative hyphae 3-6 µm diameter, walls 0.2 µm thick, often encrusted,
sometimes inflated between septa, with clamp connections. Hymenial layer either
a continuous palisade, or composed of short lateral branches arising from
rhizomorphs and bearing 2-5 basidia and paraphyses. Basidia cylindrical or
subclavate, 8-12 x 6-7 µm, bearing 4 spores; sterigmata slender, to 6 µm long.
Paraphyses subclavate, 6-8 x 5-6 µm. Spores subglobose, oval, or broadly
elliptical, 5-7 x 4-5.5 µm (including spines), walls finely and closely
echinulate, hyaline, 0.2 µm thick; spines to 4 µm long.
Habitat: HABITAT: Effused on decorticated. decayed wood and fern stipes.
Distribution: DISTRIBUTION: Europe,
Great Britain, North America, New Zealand.
Notes: Taxonomists differ as to whether the species should be placed under
Corticium or Tomentella. Because spores are hyaline and the
hymenium is frequently arranged in the form of a definite palisade, it is
treated as a Corticium herein. The collection from the Ruahine Ranges
exhibits the Tomentella structure, the others the Corticium
form seen in some European collections. The species may be separated from C.
tulasnelloideum, which it resembles in the echinulate spores, by the
conspicuous yellow colour of the surface and usual presence of rhizomorphs
either in the context or at margins. Colour sometimes fades from the central
portions, but is retained in the margins. An extensive synonymy is given by
Rogers & Jackson (1943, p. 308).
