Description: Pileus -12 mm, hemispheric to convex, expanded with age; argillaceous to pale brown with distinct ochraceous, copper-red or rust-brown tinge over disc; distinctly granular to subsquamulose when young (squamules appear conic to wart-like under the hand-lens), becoming farinaceous or micaceous with age; dry, not hygrophanous, margin substriate, conspicuous veil remnants absent. Lamellae (L 6-8,-3) moderately crowded to subdistant, adnate to adnexed, ventricose; concolorous with pileus or paler, often with ochraceous tinge, becoming pale fuscous with age, edge albofimbriate. Stipe -25 x -1.5 mm, cylindric, equal, central; upper half concolorous with pileus, lower half becoming dark brown with age; pruinose near apex, fibrillose or waned towards base; dry, hollow, single in groups, cortina absent. Context pale brown. Odour none or acidic. Spores 7-9 x 4.5-5.5 µm, distinctly limoniform, pale yellow-brown, membrane thin-walled germ pore absent, smooth. Basidia 20-30 x 6-8 µm, 4-spored, rarely 2-spored. Cheilocystidia 30-55 X, 6-8 µm, fusoid, slender, membrane hyaline or pale-yellow-brown, forming dense seam on edge, clamp connection on basal septum. Pleurocystidia none. Caulocystidia like cheilocystidia but larger. Cuticle composed of irregularly arranged chains of globose. to ovoid cells, with brown (KOH) membranous and encrusting pigment, membrane not gelatinised. Clamp connections numerous.
Habitat: on rotting leaves, stems, and wood of dicotyledonous plants and mosses (Nothofagus spp., Weinmannia racemosa Linn.f., Brachyglottis repanda J. R. et G. Forst., Sphagnum). New Zealand
Notes: All morphologic aspects of F. pulveraceus are typical for the genus Flammulaster. Taxonomically this species has several close relatives not only in New Zealand (F. foliicola) but also in other regions both in the Southern and Northern Hemispheres, i.e., F. mucronosporus (Singer 1953) in Argentina and Chile, F. gregarius (Singer 1956) in the USA, and F. curpophilus (Fries) Singer in Europe (compare also Moser 1978:301).
