Corticium cebennense Bourdot 1910

RUBIACEAE. Coprosma australis: Auckland, Ruatewhenua, Waitakere Ranges, 300 m.
Hymenophore annual, membranous, somewhat loosely attached, effused forming small linear colonies 2-6 x 2-3 cm; hymenial surface white, drying cream or pallid straw, even, not creviced; margin thinning out, white, arachnoid, adherent. Context white, 100-200 µm thick, basal layer narrow, of parallel hyphae, intermediate layer of erect loosely arranged hyphae branched at a wide angle; generative hyphae 4-5 µm diameter, walls 0.2 µm thick, naked, with clamp connections. Hymemal layer to 50 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate or subcylindrical, 20-26 x 5-6 µm, bearing 2-4 spores; sterigmata slender, 7-10 µm long. Paraphyses subclavate, 18-22 x 5-6 µm. Spores allantoid, or rod-shaped with rounded ends, 7-9 x 1.5-2 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Europe, New Zealand.
HABITAT: Effused on decorticated dead wood.
Context hyphae are naked and the context is without crystals or granules of mucilage. Specific features are the long and narrow allantoid or rod-shaped spores with two prominent guttulae, moderately thick hyphae branched at a wide angle, and small elliptical colonies with cream or ochre, even, non-creviced surface. Our collection agrees with a specimen ex Stockholm examined in Kew herbarium, differing in being non-creviced, and growing upon a different host. In microfeatures they agree closely.
TYPE LOCALITY: Aveyron, France.
