Russula aucklandica McNabb 1973

Under L. ericoides, Auckland: Titirangi, Bishop's Reserve, 8.iii.l967, R. F. R. McN. (pdd 26547)-, 13.iv.l967, R. F. R. McN. (PDD 26591); 13.iv.l967, R. F. R. McN. (holotype, pdd 26590)
pileus: 4-8.5 cm diam., hemispherical to convex when young, centrally depressed at maturity, slightly viscid under wet conditions, otherwise dry, glabrous, pruinose to subvelutinate under lens, velar remnants absent, dark greyish red, vinaceous, ruby, or ruby with purple tints in centre, typically paling towards margins, often with yellowish brown, greenish brown, or brownish purple areas; margins entire, non-pectinate. Cuticle composed of erect, thin-walled, smooth, aseptate or occasionally septate, hair-like hyphae to 100 µm long, 4.5-7 µm diam., without staining contents in KOH, tapering apically, originating from non-inflated or occasionally slightly inflated, short-celled hyphae; pilocystidia absent. lamellae: adnate, moderately crowded, moderately thick, simple or forked near stipe, to 9 mm deep, pallid creamy white, not discoloured at maturity, lamellulae absent. stipe: 2.5-6 cm long, ± equal or tapering basally, 1-2 cm diam., dry, solid, finely furfuraceous to pruinose under lens, greyish red to greyish ruby, typically paling apically; flesh white, firm, unchanging on exposure to air. Cuticle composed of a close palisade of hair-like hyphae similar to those of pileus; caulocystidia absent. spores: spore print cream; spores broadly elliptical, obliquely apiculate, apiculus to 1.5 µm long, 7.5-9 X 6.5-8.5 µm, ornamentation of amyloid crests and ridges to 0.7 µm high, forming an almost complete reticulum; plage absent. hymenium: basidia hyaline, clavate, 39-52 X 9-12 µm, 4-spored, sterigmata to 5 µm long, pleurocystidia scattered, numerous, fusiform, hyaline, thin-walled, contents sparse, projecting to 50 µm beyond basidia, apices acuminate, 77-122 X 8.5-14 µm; cheilocystidia numerous, projecting, 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—rapidly salmon pink, darkening with time; KOH on pileus— orange-brown to yellowish brown; on context—n.r.; NH4OH on pileus and context—n.r.
Gregarious under Leptospermum.
Pileus convexus centraliter depressus, 4-8.5 cm diam., atrogriseo-ruber ad vinaceum ad margines pallescens, siccus, glaber; veli vestigia deficiunt; margines integri, non pectinati. Lamellae adnatae ad 9 mm altae, pallide cremeae; lamellulae deficiunt. Stipes 2.5-6 cm longus, plus minusve aequalis vel basim angustatus, 1-2 cm diam., concolor cum pileo. Sporae late ellipticae 7.5-9 x 6.5-8.5 µm, amyloides sparse ornatae.
