pileus: 2-5 cm diam., convex when young, centrally depressed at maturity, slightly viscid under wet conditions, otherwise dry, innately subpruinose under lens, velar remnants absent, greyish magenta, greyish violet, or deep vinaceous-purple, often with olive green or yellowish green areas; margins entire, non-pectinate. Cuticle composed of erect, hyphae and pilocystidia, often disorganised and partially gelatinised with age; hyphae thin-walled, smooth, septate, 1.5-6 µm diam., terminal cells unspecialised, tapering apically, originating from inflated, short-celled hyphae or sphaerocysts, pilocystidia cylindrical to subclavate, often septate, thin-walled, apices bluntly acuminate or mucronate, contents refractive in KOH, occasionally projecting to 60 µm beyond general level of cuticle, 40-150 X 5-10 µm. lamellae: adnate, crowded, thin, simple or occasionally forked near stipe, to 6 mm deep, white to pallid creamy white, not discoloured at maturity, lamellulae rare or absent. stipe: 1.5-4 cm long, ± equal or expanded basally, 0.6-1.3 cm diam., dry, solid or slightly chambered, finely furfuraceous under lens, pallid greyish red, rose, or pallid greyish magenta with rose tints, often with white flesh showing through; flesh white, unchanging on exposure to air. Cuticle composed of interwoven, repent, thin-walled, septate hyphae 2.5-4 µm diam., terminal cells projecting and aggregated into clumps; caulocystidia numerous, similar to pilocystidia. spores: spore print pallid creamy white; spores broadly elliptical to ovate, obliquely apiculate, apiculus to 1.5-(2) µm long, 9-10.5 X 7.5-9 µm, ornamentation moderately dense, of amyloid or partially inamyloid, truncated spines to 1 µm high, in small confluent groups, joined basally by fine to moderately coarse amyloid ridges and forming nodulated bands or an incomplete reticulum, or occasionally isolated; plage conspicuous. hymenium: basidia hyaline, clavate, 36-45 X 10.5-13 µm, 4-spored, sterigmata to 8 µm long; pleurocystidia scattered, numerous, broadly fusiform, hyaline, thin-walled, contents refractive in KOH, projecting to 35 µm beyond basidia, apices acuminate, strangulate, or capitulate, 60-100 X 7.5-13.5 µm; cheilocystidia rare to numerous, similar to pleurocystidia but shorter. hymenophoral trama: heteromerous, intermixed. context of pileus: white, unchanging; structure heteromerous, 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—magenta colour disappears leaving area orange-red: on context —n.r.; NH4OH on pileus and context—n.r.

Solitary or in pairs under Nothofagus.

Pileus centraliter depressus 2-5 cm diam., griseo-violaceus, leviter viscidus, subpruinosus; veli vestigia deficiunt; margines integri, non pectinati. Lamellae adnatae ad 6 mm altae pallide cremeae; lamellulae rarae. Stipes 1.5-4 cm longus, plus minusve aequalis vel basim dilatatus, 0.6-1.3 cm diam., solidus, vel parum cavatus, concolor cum pileo. Sporae late ellipticae ad ovatas 9-10.5 x 7.5-9 µm, amyloides vel inamyloides dense ornatae.
