Specimen notes
Public Note:
[McNabb:] #123 (originally as inconspicua/miniatorubra). PILEUS: 0.7-0.5cm diam., convex when young, becoming slightly centrally depressed, smooth, slightly viscid, innately pruinose and rather faintly creviced, no velar remnants, rather bright red (c 10A5-A6). GILLS: free, rather distant, pure white, lamellulae present but in no sequence, to 2.5mm deep. STIPE: 1.5cm long, curved, more or less equal, c 3mm diam., solid, pure white, annulus absent, finely felted under lens. CONTEXT: white unchanging. CHEMICAL CHARACTERS: guaiacol on stipe base – no immed. reaction. HABITAT: solitary under Nothofagus menziesii; Nelson, Karamea, Umere, 2.1.1968. Coll. R.F.R. McNabb. ILLUSTRATIONS: none. Cuticle of pileus consisting of hairs to 75(-100) um long, septate 2-4 times, thin-walled, slightly tinted in KOH, devoid of content, 3.5-5um diam., terminal cells acuminate, unspecialised, individual cells sometimes slightly inflated smooth, slightly thickened walls in some hairs. Hairs projecting obliquely, originating from inflated cells of sphaerocysts. Sphaerocysts forming a layer of cellular appearance. No indications of pilocystidia projecting into sphaerocyst layer. Cuticle of stipe rather disorganised but apparently consisting of hyaline interwoven +- repent hyphae with terminal cells projecting 3.5-5um diam., certainly no indications of hairs arising from sphaerocysts. Basidia hyaline, clavate, 4-spored, sterigmata to 8um long, 36 – 44 x 10 – 13.5um. Pleurocystidia projecting to 15um beyond basidia, numerous scattered, broadly fusiform with acuminate or mucronate apices, hyaline, thin-walled, with refractive content in KOH 46-63 x 8.2-12um. No indications of specialised cheilocystidia. Spores broadly ellipsoid, to ovate, obliquely apiculate, apiculus to 1.5um long, 9.8 – 11.3 x 8.2 – 10um. Ornamentation of isolated truncated spines, coarse amyloid to 1.5(2)um high, isolated or confluent basally in groups of 2-3, or occasionally joined basally with fine to moderately coarse amyloid ridges and then forming an incomplete reticulum. [Ridley:] Basidiospores 7.25-8.5 x 6.5-7.25 um, [9.5-11.5 x 8-10 um] Qm 1.19, broadly ellipsoid Q 1.11-1.26, subglobose to broadly ellipsoid, hyaline. Ornamented with moderately crowded, amyloid, truncate spines to 1(-1.5) um high, occasionally single but mostly confluent groups of two to three, joined by fine, low, amyloid ridges forming a partial reticulum. Suprahilar plage distinct, flaking, weakly amyloid to amyloid, c. 2.75 um wide. Hilar appendix obconical, obJique, to 2(-2.75)um long. (Fig. 28d). The plage was distinct, being outlined by the truncate spines, and the intensity of the amyloid reaction variable. Spore ornamentation was type IIB.[Cooper:] Very small fragments of 2 tiny fruitbodies. DCY visible in SV but not staining, or if so then very weakly, SV-ve, pigment leaching. Cap hairs arising from sphaerocysts, yellow in KOH, sometimes with refractive content. Spores length=7.8–9.8µm (µ=8.5, σ=0.4), width=6.5–8.1µm (µ=7.1, σ=0.4), Q=1.1–1.3µm (µ=1.21, σ=0.05), n=20, ornamentation to 1.8um.
