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, ceraceous,
adherent, effused forming linear areas to 12 x 5 cm; hymenial surface cream,
pallid alutaceous, or ochre, becoming deeply areolately creviced; then appearing
tuberculate; margin thinning out, concolorous, byssold, adherent. Context white,
100-400 µm thick, basal layer narrow, of loosely arranged mainly parallel
hyphae, intermediate layer of erect hyphae more densely compacted in the
subhymenium, embedding masses of crystals which may be arranged in layers;
generative hyphae 3.5-4 µm diameter, walls 0.2 µm thick, encrusted, without
clamp connections. Hymenial layer to 40 µm deep, a close palisade of basidia and
paraphyses. Basidia subclavate, 14-32 x 4-6 µm, bearing 2-4 spores; sterigmata
slender, to 8 µm long. Paraphyses cylindrical or subclavate, 14-28 x 4-5 µm.
Spores oval, ovate, or broadly elliptical, 4-5-6 x 3.5-4 µm, walls smooth,
hyaline, 0.2 µm thick. Habitat: HABITAT: Effused on bark or decorticated dead
branches. Distribution: DISTRIBUTION: Europe, Great Britain, Australia, New
Zealand. Notes: Collections listed agree with a specimen of C.
tuberculatum examined in Kew herbarium, differing mainly in the brighter
colour of the surface and, particularly, in the masses of crystals present in
the context. In specimens from Griselinia lucida crystals are confined
to the basal part of the context, whereas in those from Nothofagus
cliffortioides they extend to the hymenial layer, lying between and partly
encrusting basidia and paraphyses. Australian collections bear only a few
crystals, hyphae of the context being encrusted with mucilage granules. Margins
of crevices in old specimens often lift slightly and give to plants an odontoid
appearance. When plants are actively growing the surface is even although deeply
creviced.
