Russula pudorina McNabb 1973
Under (1) L. ericoides, Auckland: Titirangi, Atkinson Park, 4.iv.l967, R. F. R. McN., (holotype pdd 26574). (2) L. scoparium. Auckland: Henderson Valley, Sharp's Bush, 20.ii.l967; 6.iv.l967, R. F. R. McN. (pdd 26573, 26543).
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.
Solitary under Leptospermum.
Pileus plano-convexus, centraliter depressus 2.5-4 cm diam., rubro-griseus, siccus, glaber; veli vestigia deficiunt; margines integri, non pectinati. Lamellae adnexae ad 5 mm altae cremeo-albae; lamellulae rarae. Stipes 2-2.5 cm longus, plus minusve aequalis, 0.5-0.8 cm diam., siccus, solidus, concolor cum pileo. Sporae obovatae ad late ellipticas 8-10.5 x 7-9 µm, amyloides ornatae.
