Description:Gloeocystidiellum zawitense Rattan, Abdullah & Ismail sp. nov.
Fructifications resupinate, pelliculose to membranous, loosely adnate, widely effused, up to 400 µm thick in section; hymenial surface deep cream to cream yellow or creamish grey, smooth to finely colliculose, not creviced; margin thinning, adnate, fibrillose, white to paler concolorous. Context subhyaline in section, composed of loosely woven hyphae, without any distinction into basal or upper zone, containing abundant crystalline matter. Hyphal system monomitic, hyphae 2.5-4.5(-6) µm wide, subhyaline, branched at wide angles, branches usually arising below the septa, clamps absent, thin-to moderately thick-walled, walls up to 0.5 µm thick, often crystal incrusted. Cystidia absent. Gloeocystidia 70-150 x 8-11 µm, cylindrical to flexuous, empty or with subhyaline granular contents staining deeply with phloxine, thin-walled, apices obtuse, often arising from the upper part of context, immersed or projecting up to 30 µm, usually covered with irregular, subhyaline crystals especially on the projecting part, turning black with sulfobenzeldehyde reagent. Hymenium compact, composed of basidia and basidioles. Basidioles narrower than basidia, of variable length and often with capitate apices, sparsely crystal incrusted. Basidia 30-40 x 7-9 µm, clavate-cylindrical, 4-spored, sterigmata curved an up to 6 µm long. Basidiospores 8-10(-12) x 5.5-6(-8) µm, ellipsoid, subhyaline, minutely apiculate, the walls thin, smooth, amyloid, acyanophilous.
