Specimen notes
Public Note:
[McNabb:] Holotype = 129 (Group 5, =paintng K2). PILEUS: 6cm. diam., infundibulliform, smooth, no indications of velar remnants, viscid, margins sulcate for ½ distance between edge and centre, ridges darker than grooves, brownish-yellow; margin incurved, entire, thin. GILLS: crowded, pallid cream, not discoloured, lamellulae absent, 5mm deep, gills occasionally forked near stipe, not near margins, slightly decurrent. STIPE: 6cm long, 1.5cm diam. apically, 2cm basally, smooth, white with brownish overtones, hollowed, faintly longit. striate under lens, no annulus, flesh dingy white. CONTEXT: dingy white, unchanging, rather granular. TASTE: gills and context – not distinctive. CHEMICAL CHARACTERS: formalin – n.r. Phenol – slowly dull vinaceous; FeSO4 – immed. dull salmon pink; guaiacol on stipe base – immed. dull brick red, darkening with time. KOH on pileus darkening; on context – n.r. NH4OH on pileus and context – n.r. HABITAT: solitary under Nothofagus menziesii, Nelson, Karamea, Umere, 5.1.1968, R.F.R. McNabb. ILLUSTRATIONS: Painting K2. Cuticle of pileus consist of a thick layer of +- gelatinised, hyaline, thin-walled, septate hyphae 2-4um diam., +- repent and interwoven. Pilocystidia numerous, with yellowish contents, contents rather homogenous than crystalline and refractive in KOH, 5-8um diam, often deeply embedded and tortuous, projecting slightly in places. Ends of hyphae often forming a disorganised palisade of erect or oblique hyphae. Cuticle of stipe compressed or repent, parallel, to interwoven hyphae, hyaline, thin-walled, septate. Caulocystidia projecting obliquly in places, smaller to pilocystidia, sparse. Basidia hyaline, clavate 4-spored, sterigmata to 6.5um long, 42-57 x 9-13.5um. Pleurocystidia scattered, not particularly numerous, thin-walled, contents not as conspicuous as other spp. rather more homogenous than crystalline, broadly fusiform or subclavate with capitulate or mucronate apices. Not, or projecting to 35um beyond base, 45-117 x 6.8-10.5um. Spores ovate to obovate, obliquely apiculate, apiculus to 1.5(-2) um long. 10.5-11.2 x 7.5-9.8um ornamentation of coarse amyloid crests or verrucae to 1.5um high, isolated or joined by very fine ridges to give an incomplete reticulum. Plage not distinctive. [Ridley:] Basidiospores 8-9.5 x 6.5-8 um, [9.5-11.5(-12.5) x 8.5-10 um], Qm 1.19, broadly ellipsoid, Q 1.13-1.26, subglobose to broadly ellipsoid, hyaline. Ornamented with crowded, amyloid crests and verrucae, to 1.25 um high, in confluent groups, joined by moderately low to low, finely amyloid, or more usually inamyloid ridges, forming a partial reticulum. Suprahilar plage distinct, amyloid, finely flaking, c. 2.75 um wide. Hilar appendix obconical, oblique, to 1.75 um long. (Fig. 25d). The plage was originally described as inconspicuous, however it was observed to be both distinct and amyloid. The ornamentation was type IIIB. [Cooper:] No lamelullae. Gills strongly basally interveined. DCY are strongly SV+ve, and vermiform refractive in KOH. With a plage and amyloid spot, although it is not clear. Spores from print length=7.7–9.8µm (µ=9.0, σ=0.5), width=6.6–8.2µm (µ=7.6, σ=0.4), Q=1.1–1.4µm (µ=1.2, σ=0.1), n=20. Ornamentation to 1um high. Spore measurements agree with Ridley.
