Russula subvinosa McNabb 1973
Under (1) L. ericoides, Auckland: Titirangi, Atkinson Park, 24.iii.l967, R. F. R. McN. (PDD 26633); l.iii.l967, R. F. R. McN. (PDD 26546): 7.iii.l967, R. F. R. McN. (holotype, PDD 26641); ll.iv.l967, R. F. R. McN. (PDD 26586); Birkenhead, Kauri Glen Park, I.V.1971, B. S. Parris (PDD 29440). (2) N. menziesii. Nelson: Karamea, Umere, 4.i.l970, R. F. R. McN. (3) N. truncata, Auckland: Rotorua, Mangorewa Gorge, 25.iv.l967, R.F.R. McN. (PDD 26594).
pileus: 4-6.5 cm diam., convex when young, centrally depressed at maturity, slightly viscid under wet conditions, otherwise dry, glabrous to finely rugulose, pruinose to subvelutinate under lens, velar remnants absent, greyish pink, greyish red, dull red, or pallid vinaceous, occasionally deep vinaceous in centre, often mottled greyish pink and white, typically with grey overtones in dry weather, sometimes with greenish yellow areas; margins entire, non-pectinate. Cuticle composed of erect, thin-walled, smooth, septate or aseptate, hair-like hyphae to 50 µm long, without staining contents in KOH, tapering apically, originating from slightly to moderately inflated, short-celled hyphae, becoming disorganised with age; pilocystidia absent. lamellae: adnate, moderately crowded, thick, simple or forked near stipe, to 7 mm deep, cream, not discoloured at maturity, lamellulae present. stipe: 2-4 cm long, ± equal or tapering basally, 1-2 cm diam., dry, solid, finely felted under lens, white to pallid creamy white; flesh white, unchanging on exposure to air. Cuticle composed of a loose palisade of hair-like hyphae similar to those of pileus, soon disorganised with age; caulocystidia absent. spores: spore print pallid ochre; spores elliptical to broadly elliptical, obliquely apiculate. apiculus to 1.5 µm long, 9-11 X 8-9.5 µm, ornamentation of rather sparse, amyloid or partially inamyloid crests and ridges to 1.2-(1.6) µm high, forming an almost complete reticulum; plage conspicuous. hymenium: basidia hyaline, clavate, 35-52 X 11-15.5 µm, 4-spored, sterigmata to 7 µm long; pleurocystidia scattered, numerous, fusiform, hyaline, thin-walled or slightly thick-walled, contents sparse, projecting to 30 µm beyond basidia, apices acuminate, or protracted and capitulate, 63-91 X 7-12.5 µm; cheilocystidia rare to moderately numerous, similar to pleurocystidia but shorter. hymenophoral trama: heteromerous, intermixed. context of pileus: white, firm, 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 pallid salmon pink; KOH and NH4OH on pileus and context—n.r.
Solitary or occasionally in pairs under Leptospermum and Nothofagus.
Pileus convexus centraliter depressus 4-6.5 cm diam., griseo-ruber, siccus, glaber; veli vestigia deficiunt; margines integri non pectinati. Lamellae adnatae ad 7 mm altae, cremeae; lamellulae adsunt. Stipes 2-4 cm longus, aequalis vel basim angustatus, 1-2 cm diam., siccus, solidus, pallide cremeus. Sporae ellipticae ad late ellipticas 9-11 x 8-9.5 µm, amyloides ornatae.
This species belongs to the section Rigidae and is possibly best placed in subsection Amoeninae as defined by Singer (1962), but spore print is slightly coloured.
Collections associated with Nothofagus spp. perhaps do not entirely agree in spore ornamentation with those from under Leptospermum, and in their chemical relation with KOH, but for the time being it seems best to include them under the same species.
