Description: pileus: 3-6 cm diam., convex when young, centrally depressed at maturity, slightly to moderately viscid, glabrous, velar remnants absent, white to sordid white with faint greyish magenta, greyish purple, or reddish grey tints in centre; margins entire, non-pectinate. Cuticle composed of erect or obliquely ascending, interwoven, thin-walled, smooth, septate hyphae 3-5 µm diam., terminal cells unspecialised, becoming disorganised and gelatinised with age; pilocystidia absent. lamellae: adnexed to adnate, crowded, thin, simple or occasionally forked near stipe, to 5 mm deep, white, not discoloured at maturity, lamellulae rare. stipe: 3-6 cm long, ± equal or expanded basally, 1-1.8 cm diam., dry, solid, white; flesh white, unchanging on exposure to air. Cuticle composed of interwoven, repent, thin-walled, septate hyphae 2.5-5 µm diam., terminal cells projecting, aggregated into clumps; caulocystidia absent. spores: spore print not obtained; spores broadly elliptical, obliquely apiculate, apiculus to 1.5-(2) µm long, 9-12 X 8.5-10.5 µm, ornamentation dense, of amyloid or partially inamyloid, truncated spines to 1.5 µm high, in small confluent groups, joined basally by fine amyloid ridges and forming a partial reticulum, or isolated; plage conspicuous. hymenium: basidia hyaline, clavate, 42-66 X 10-14 µm, 4-spored, sterigmata to 8 µm long; pleurocystidia scattered, numerous, subclavate to fusiform, occasionally I- or 2-septate, hyaline, thick-walled, walls to 2 µm thick at mid point, thinner at base and apex, contents sparse, projecting to 20 µm beyond basidia, apices rounded, acuminate, or occasionally irregularly acuminate, 45-88 X 9-14 µm, cheilocystidia numerous, similar to pleurocystidia but shorter and thinner walled. hymenophoral trama: heteromerous, intermixed. context of pileus: clamp connections absent. taste: lamellae and context mild. chemical characters: formalin on context—n.r.: phenol on context—slowly deep vinaceous; FeSO4 on context—rapidly salmon pink; guaiacol on stipe base—n.r.; KOH on pileus—colour disappears in pigmented areas leaving tested portion orange-red; on context—n.r.; NH4OH on pileus and context— n.r.
Habitat: Solitary or gregarious under Nothofagus.
