Description: pileus: 2.5-4 cm diam., convex when young, plano-convex
to slightly centrally depressed at maturity, slightly viscid under wet conditions,
otherwise dry, glabrous or occasionally finely creviced under dry conditions,
finely subpruinose under lens, velar remnants absent, reddish grey, greyish
ruby, rose, or pallid red; margins entire, non-pectinate. Cuticle composed of
erect, thin-walled, smooth, septate, hair-like hyphae to 100 µm long, 3-6.5
µm diam., without coloured contents in KOH, terminal cells unspecialised, tapering
apically, originating from inflated, short-celled hyphae; pilocystidia absent.
lamellae: adnexed, moderately crowded, moderately
thick, simple or occasionally forked near stipe, to 5 mm deep, white to pallid
creamy white, not discoloured at maturity but edges often tinted with colours
of stipe, lamellulae rare. stipe: 2-2.5 cm long, ± equal, 0.5-0.8 cm diam.,
dry, solid, finely felted to subpruinose under lens, concolorous with or paler
than pileus. White flesh often showing through (in places); flesh white, unchanging
on exposure to air. Cuticle composed of interwoven, repent, thin-walled, septate
hyphae 3.5-5 µm diam., terminal cells projecting and aggregated into clumps;
caulocystidia absent. spores: spore
print white; spores obovate to broadly elliptical, obliquely apiculate, apiculus
to 1.5-(2) µm long, 8-10.5 X 7-9 µm. ornamentation of amyloid verrucae to 0.7
µm high, joined by fine to moderately coarse amyloid ridges and forming an incomplete,
nodulated reticulum, in small confluent groups, or occasionally isolated: plage
conspicuous. hymenium: basidia hyaline, clavate, 35-53 X 9.5-14.5
µm, 4-spored, sterigmata to 8.5 µm long; pleurocystidia scattered, numerous,
fusiform to broadly fusiform, hyaline, thin-walled, contents sparse, projecting
to 40 µm beyond basidia, apices acuminate, mucronate, or occasionally strangulate,
55-110 X 6.5-16 µm; cheilocystidia numerous, similar to pleurocystidia but shorter.
hymenophoral trama:
heteromerous, intermixed. context
of pileus: white, unchanging; structure heteromerous,
clamp connections absent. taste: lamellae and context slowly extremely
bitter. chemical characters: formalin on context—n.r.; phenol on context—slowly
deep vinaceous; FeSO4 on context—rapidly faint salmon pink; KOH and NH4OH on
pileus and context—n.r.
Habitat: Solitary under Leptospermum.
