Description: Pileus 10-40 mm diam., convex becoming applanate with ± distinct shallow umbilicus at the centre, margin expanded, dark brown (tobacco), densely covered by concolorous squamules or (near the centre) scales, striate towards the margin, dry, hygrophanous. Lamellae (L 10-15, 1 3(7), emarginate adnate, brownish, turning pink-brownish, gill edge concolorous, not fimbriate. Stipe (25) 30-90 x 2-3.5 mm, cylindrical or somewhat attenuated towards the base, whitish-brownish, pruinose (at least apically), stiff, twisted, fragile, dry, fistulose. Context brownish. Odor and taste none or slightly farinaceous.
Spores 10-12 x 10-12 µm, mostly 5-sided, with prominent knobs, complex. Basidia 30-38 x 10-13 µm, 4-spored. Cheilocystidia (and pleurocystidia) 55-120 x 12-25 µm, fusoid or ampullaceous, the distinct mucro apically rounded, membrane thin-walled, hyaline, sometimes coloured by brownish, plasmatic pigment. Caulocystidia 40-85 x 10-20 µm, clavate, hyaline, in clusters. Cuticle a cutis of cylindrical, repent or suberect hyphae (8-17 µm diam.), membrane thin-walled, not gelatinized, with brown, plasmatic pigment. Clamp connections abundant.
Habitat: On soil among mosses and litter in forests (under Beilschmiedia, Weinmannia, Coprosma, Cyathea, etc.) or on rotten wood (of Nothofagus spp.). New Zealand.
Notes: Macroscopically, in its scaly pileus, pruinose stipe and colouring, E. squamiferum resembles E. acuticystidiosum Hk. but the species can easily be distinguished by the different size and shape of the spores and the form of the cheilo- and pleurocystidia respectively.

Description: Pileus 10-25 mm diam., hemispherical, becoming convex, aged carpophores pulvinate and often depressed or subconcave at the centre, margin incurved. brown, covered by soot-brown fibrils and scales, dry, neither striate nor hygrophanous. Lamellae (L 10-16, l 1-3) adnate-emarginate, whitish when young, becoming grey-pink, gill edge concolorous, not fimbriate. Stipe 20-40 x 2-3 mm, cylindrical, often curved near the base, grey or purplish brown, densely covered by concolorous dots at least near the apex, dry, hollow, solitary or in clusters. Context light brown. Odor and taste not distinctive.
Spores 12-14 x 11-13 µm, 5-6-sided, with prominent knobs. Basidia 45-52 x 10 µm. 4-spored. Cheilocystidia 70-110 x 10-20 µm, awl-shaped, membrane thin-walled, hyaline. pleurocystidia none. Caulocystidia 60-100 x 10µm, clavate, often curved. Cuticle a cutis of cylindrical, repent or suberect hyphae (10-15 µm diam.), membrane thin-walled, with conspicuous, brown, plasmatic pigment. Clamp connections present.
Habitat: On soil in forests (under Dacrydium, Beilschmiedia, Elaeocarpus, Dicksonia, etc.). New Zealand.
Notes: This species is distinguished by its large, complex spores, awl-shaped cheilocystidia, presence of conspicuous caulocystidia and scaly pileus. Macroscopically it resembles E. squamiferum Hk. (see discussion there).
