Russula miniata McNabb 1973
Under N. menziesii, Nelson: Karamea, Umere, 2.i.l968, R. F. R. McN. (HOLOTYPE, pdd 30652).
pileus: 0.7-1.5 cm diam., convex when young, slightly centrally depressed at maturity, slightly viscid, under wet conditions, otherwise dry, glabrous or finely creviced, innately pruinose under lens, velar remnants absent, pallid red to pastel red; margins entire, thin, faintly pectinate in places. Cuticle composed of erect, thin-walled, or slightly thick-walled, smooth, septate, hair-like hyphae to 100 µm long, 3.5-5 µm diam., hyaline or tinted yellow, occasionally with yellowish contents in KOH, terminal cells unspecialised, tapering apically, originating from a layer of inflated, sphaerocyst-like cells 5-10 cells deep; pilocystidia absent. lamellae: adnexed, moderately distant, thin, simple, to 2,5 mm deep, white, not discoloured at maturity, lamellulae rare. stipe: 1-1.5 cm long, ± equal, 3-4 mm diam., dry, solid, finely felted under lens, white: flesh white, unchanging on exposure to air. Cuticle composed of interwoven, repent, thin-walled, septate hyphae 3.5-5 µm diam., terminal cells often projecting and aggregated into clumps: caulocystidia absent, spores: spore print not obtained; spores ovate to broadly elliptical, obliquely apiculate, apiculus to 1.5 µm long, 9.5-11.5 X 8-10 µm, ornamentation of dense, amyloid, truncated spines to 2 µm high, in small confluent groups, joined basally by fine to moderately coarse amyloid ridges and forming an incomplete reticulum, or occasionally isolated; plage conspicuous. hymenium: basidia hyaline, clavate, 36-44 X 10-13.5 µm, 4-spored, sterigmata to 7 µm long; pleurocystidia scattered, numerous, fusiform, hyaline, thin-walled, contents refractive in KOH, projecting to 15 µm beyond basidia, apices acuminate or mucronate, 46-63 X 8-12 µm, cheilocystidia absent. hymenophoral trama: heteromerous, intermixed. context of pileus: white, unchanging; structure heteromerous, clamp connections absent. chemical characters: guaiacol on stipe base—n.r.
Solitary under Nothofagus.
Pileus convexus centraliter depressus 0.7-1.5 cm diam., pallide ruber, siccus, glaber; veli vestigia deficiunt; margines integri, tenues, leviter pectinati. Lamellae adnexae ad 2.5 mm altae, albae; lamellulae rarae. Stipes 1-1.5 cm longus, plus minusve aequalis, 3-4 mm diam., siccus, solidus, albus. Sporae ovatae ad late ellipticas 9.5-11.5 x 8-10 µm, amyloides dense ornatae.
This species belongs in the section Rigidae and is possibly best placed in the subsection Amoeninae as defined by Singer (1962).
