[McNabb:] #159 (holotype), group 22. PILEUS: 2-4 cm diam., dry finely pruinose under lens, dark greyish magenta with black sooty appearance in places (dry weather form) margins entire, non pectinate. GILLS: creamy to almost pallid ochraceous, crowded, simple or occasionally branched, lamellulae sparse or absent, not discoloured, to 5mm deep. STIPE: 2-4.5cm long, slightly expanded basally, 0.5-1cm diam., solid or slightly chambered at maturity, pink to pinkish red with white flesh showing through in places. CONTEXT OF PILEUS: white unchanging. TASTE: gills and context mild. CHEMICAL CHARACTERS: formalin – n.r phenol – slowly deep vinaceous; FeSO4 definitely greyish green; guaiacol on stipe base – faint magenta tints bit not a positive reaction; KOH on pileus – magenta colours removed leaving area brick-red orange; con context – n.r. NH4OH on pileus and context no reaction. HABITAT: gregarious under Nothofagus solandri, Canterbury, Kowai Bush, 5.2.1969, Coll. R.F.R. McNabb. Cuticle of pileus with a +-vinaceous structure: composed of a layer of rounded sphaerocysts cells c 10 cells deep, with terminal hairs to 150um long, tinted, septate, thin-walled, 3.5-5um diam., +- oblique to semi-erect. Pilocystidia absent. Cuticle of stipe composed of interwoven septate hyphae 3.5-5.5um diam., aggregated into clumps and ends projecting. Terminal cells inconspicuous. Caulocystidia absent. Hairs similar to those on pileus but not arising from sphaerocysts. Basidia hyaline, clavate, 4-spored, 39-47 x 12-15um. Pleurocystidia scattered, numerous, not projecting beyond basidia or to 15um occasionally, hyphae thin walled, contents not particularly refractive in KOH, rather sparse, broadly fusiform, 51-68 x 12 – 16.5um, apices acuminate occasionally capitulate or strangulate. Cheilocystidia not distinctive but a few short pleurocystidia on gill edge. Spores broadly elliptical slightly obliquely apiculate, apiculus to 1.5(2) um long, 10.5-13 x 9-11.2. Ornamentation of dense truncated spines to 1(-1.5)um long, isolated or occasionally in confluent groups of 2-3. 9.8-12.2 x 9.1-10.5, ornamentation to 1.5um high. [Ridley:] Basidiospores (7)8-9 x 6.5-8 um, [10-13 x 9-11.2 um] Qm 1.16, broadly ellipsoid, Q 1.10-1.28, subglobose to broadly ellipsoid, hyaline. Ornamented with crowded, partially amyloid to amyloid truncate spines to 1.75 um, single or occasionally in confluent groups of two or three, isolated, rarely joined by very fine, low, amyloid ridges. Suprahilar plage distinct, amyloid, in profile raised and scab-like, c. 2 pm wide. Hilar appendix obconical, oblique, to 2 um long. (Fig. 27b). Originally described simply as indistinct, this species had an unusually raised, scab-like plage which was observed both under the light microscope and SEM. The ornamentation was type IV as a reticulum was not formed. [Cooper:] subcutis not pigmented. SV-ve (definitely), exuding pink pigment, without dark granules. With plage and violet amyloid spot (not always coincident - Ridley's 'scab'). spores length=8.2–10.1µm (µ=8.8, σ=0.5), width=6.8–7.9µm (µ=7.3, σ=0.4), Q=1.1–1.3µm (µ=1.21, σ=0.05), n=20, ornamentation to 1.5um. It is clear that JAC11004, from the same site(?) is the same.
