Trechispora coronifera (Höhn. & Litsch.) D.P. Rogers & H.S. Jacks. 1943

FAGACEAE. Nothofagus fusca: Nelson, Lake Rotoiti, 700 m.
Hymenophore annual, pelliculose, adherent, effused forming irregular linear areas to 10 x 2 cm; hymenial surface bluish-white, resembling hoar frost when fresh, even or granulose, not creviced; margin thinning out, arachnoid, white, adherent. Context white, to 40 µm thick, a basal layer of parallel cemented hyphae, without an intermediate layer; generative hyphae 3.5-4 µm, diameter, to 7 µm in a few inflated basal hyphae, walls 0.1 µm thick, naked, with clamp connections. Gloeocystidia scattered, projecting for the greater part of their length, cylindrical or tapering slightly, 28-80 x 5-8 µm, walls hyaline; 0.25 µm thick, contents yellow when fresh. Hymenial layer to 30 µm deep, of scattered basidia, paraphyses, and gloeocystidia. Basidia when immature obovate or oblong, when mature each with inflated and long narrow body, urniform at apices, 10-16 x 4.5-6 µm, bearing 4-6 (8) spores; sterigmata arcuate; slender, to 5 µm long. Paraphyses scanty, cylindrical, 8-12 x 4-5 µm. Spores suballantold or obovate, 4.5-5 x 2.5-3 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe; Great Britain, North America, New Zealand.
HABITAT: Effused on bark of dead branches.
From delicate species of Corticium, Trechispora coronifera may be separated by the thin context of irregular hyphae, small projecting gloeocystidia and urniform basidia, bearing four or six, sometimes eight spores. Gloeocystidia vary appreciably in size and shape, contain yellow contents when, fresh, and soon collapse. An intermediate layer is wanting, the hymenial layer, arising directly from the basal layer of compacted, freely septate hyphae.
TYPE LOCALITY: Austria.
