[GS] Pileus 0.5-2-5 cm. diam., white becoming tinged cream, plane with downrolled margin becoming umbilicate, velvety to fibrillose, somewhat grooved or striate towards margin; flesh thin, white. Gills decurrent, white, thin, shallow, moderately distant to crowded. Stipe 0-5-2 cm. x 1-2 mm., white, centric or eccentric. Spores 5 X 3-4um, non-amyloid (Fig. 1/23, p. 10). Cuticle of loosely woven hyphae 2-5um, diam., with clamp connections, some with thickened walls. HABITAT: on fallen rotting wood or tree fern stipes, arising individually but many close together from a spreading white mycelial mat, with or without white rhizomorphs, Levin, 3.5.1947, Stevenson (type); & Levin, 18.6.1949, Stevenson. [EH] The spores are oval, smooth, neither amyloid nor dextrinoid, thinwalled, without germ-spore, 5-5.5 X 3-3.5 um. Cystidia none. Cuticle consists of cylindrical, hyaline, nongelatinised hyphae, 3-6 um, diam., with clamp-connections. [JAC] Easily distingusihed from Pleurocollybia cremea by funnel-shaped cap, decurrent gills and clamps. P. cremea can also have basal hyphal pad and rhizomoprhs. Sequences of recent material indicate this is a Rhizocybe

The spores are oval, smooth, neither amyloid nor dextrinoid, thin-walled, without germ-spore, 5-5.5 X 3-3.5 µ. Cystidia none. Cuticle consists of cylindrical, hyaline, nongelatinised hyphae, 3-6 µ. diam., with clamp-connections.

Pileus 0.5-2.5 cm diam., white becoming tinged cream, plane with down rolled margin becoming umbilicate, velvety to fibrillose, somewhat grooved or striate towards margin; flesh thin, white. Gills decurrent, white, thin, hallow moderately distant to crowded. Stipe 0.5-2 cm x 1-2 mm, white, centric or eccentric. Spores 5 x 3-4 µm non-amyloid (Fig. 23), cuticle of loosely woven hyphae 2-5 µm diam., with clamp connections, some with thickened walls.
On fallen rotting wood or tree fern stipes, arising individually but many close together from a spreading white mycelial mat, with or without white rhizomorphs, Levin, 3.5.1947, Stevenson (type); & Levin, 18.6.1949; Stevenson.
Pileus 0.5-2.5 cm diam., albus deinde cremeo-tinctus, planus, margine deorsum involute, tandem umbilicatus, velutinus usque fibrillosus, marginem versus leviter canaliculatus vel striatus; caro tenuis, alba. Lamellae decurrentes, albae, tenues, haud altae, modice distantes usque confertae. Stipes 0.5-2cm x 1-2 mm, albus, centricus vel excentricus. Sporae 5 x 3-4 µm, haud amyloideae. Cuticula ex hyphis laxe intertextis 2-5 µm diam. sistens, cum fibulis hyphis nonnullis cum parietibus incrassatis.
Typus: Stevenson 136.
