Article: Cunningham, G.H. (1963). The Thelephoraceae of Australia and New Zealand. New Zealand Department of Scientific and Industrial Research, Bulletin 145: 359 p. Wellington:.
Description: Hymenophore annual, membranous, loosely attached, effused
forming irregular areas to 5 x 3 cm; hymenial surface ferruginous, sepia, or
chocolate, velutinate, tardily creviced, sometimes granulose; margin thinning
out, concolorous, fibrillose. Context ferruginous, to 250 µm thick, basal layer
narrow, of mainly repent hyphae; intermediate layer of mainly erect hyphae
corymbose beneath the hymenial layer; generative hyphae 4-5 µm diameter in basal
hyphae, to 7 µm and slightly inflated in hyphae of the intermediate layer, walls
0.2 µm thick, pallid ferruginous, with clamp connections. Septocystidia
scattered or in irregular fascicles, some projecting to 60 µm, cylindrical with
rounded, slightly inflated apices, septate, 75-180 x 8-12 µm, walls ferruginous,
0.5 µm thick. Hymenial layer to 130 µm deep, a close palisade of basidia,
paraphyses, and septocystidia. Basidia clavate, 28-40 x 7-9 µm, bearing 4
spores; sterigmata arcuate, slender, to 8 µm long. Paraphyses clavate, 18-25 x
5-6 µm, arranged in clusters. Spores irregularly subglobose, or oblong, 9-12 x
8-12 µm, walls strongly sinuate, coarsely sparsely echinulate, fuscous, 0.5 µm
thick, spines to 2.5 µm long.
Habitat: HABITAT: Decayed bark and decorticated wood.
Distribution: DISTRIBUTION: Europe, North America, Australia.
Notes: Identified readily by the conspicuous
septocystidia, large spores with sinuate and coarsely spined walls, and
velutinate, often granulose surface of the dark hymenial layer. Septocystidia
are cylindrical with slightly rounded and inflated apices, transversely septate
with, usually, clamp connections at septa, may project to 60 µm, and are either
solitary and scattered or arranged in irregular clusters.
