Specimen notes
Public Note:
[McNabb:] #86 (grp 19) PILEUS: 4.5 cm, infundibuliform, glabrous, no indications of velar remnant, slightly viscid, subpruinose under lens with surface layer stretched circumferentially particularly towards margin and exposing the white flesh beneath, i.e. surface thrown into minute wrinkles in places, bright red (10A7-B7). margin entire, not radially marked and very thin. GILLS: white, crowded, rather thin, not discoloured except that edges of gills faintly tinted with same bright red colour of pileus, lamellae simple or very occasionally forked close to the stipe, not forked near margins, lamellulae absent, to 4mm deep. STIPE: 3.5cm long, equal, 1cm diam., dry, glabrous, annulus absent, no velar remnants, finely matte under lens, white with very faint pink-red tints in pileus. Flesh white, firm, unchanging. CONTEXT OF PILEUS: white, form, unchanging. SMELL: not noted. TASTE: gills and context not distinctive. SPORE PRINT: not obtained. CHEMICAL CHARACTERS: formalin – n.r. Phenol – n.r. FeSO4 – immed. faint pink. Guaiacol – on stipe base – slowly faint pink. KOH on pileus – beaches red colour out. KOH on context n.r. NH4OH on pileus and context – n.r. HABITAT: solitray under Nothofagus solandrii, National Park, Chateau, 1/5/1967. Col. R.F.R. McNabb. PHOTO 35mm. Note: red colour readily stains paper. Cuticle of pileus composed of a palisade of pilocystidia arising from an irregularly cellular layer. Cystidia arising from deep within the layer or from near the surface, cylindrical, or subclavate, occasionally with acuminate apices projecting beyond general level of cuticle to varying degrees. Contents vinaceous red in SV, tp 150 x 7um. Hymenophoral trama heteromerous, lateral stratum of closely packed short celled hyphae, appearing cellular in section. Mediostratum of large sphaerocysts appearing cellular in section. Spores broadly elliptical to obovate obliquely apiculate, apiculus to 1.5um long. 8.8-11.1 x 6.5-8.5um. Ornamentation of flat-topped verrucae to 1um high, usually isolated or in confluent groups of 2-3 but occasionally joined by fine amyloid lines in places. Size and density of verrucae varies considerably. No highly differentiated cheilocystidia seen on gill edge, although some structures identical to the pleurocystidia in shape are present on or near the edge in some sections. Pleurocystidia numerous, scattered, projecting to 25um beyond basidia, +- clavate or subclavate with mucronate apices, hyaline, thin-walled, contents refractive and granular in KOH, 46-70 x 7.8 – 10.4um. Basidia clavate 4-spored, sterigmata to 7um long, 33-45 x 8.4 – 10.7um. Surface of stipe composed of an interwoven layer of hyphae of small diam., 2-4.5um diam. from which arise caulocystidia. Caulocystidia +- interwoven, often with ends projecting free, thin-walled, with granular, refractive content in KOH, variously shaped, subclavate, cylindrical or fusiform with acuminate apices 42-90 x 5-7um [Ridley:] Basidiospores 8-9 x 5.25-6.5 um, [7-10 x 6.5-8 um] Qm 1.43, ellipsoid, Q1.23-1.52(-1,63), broadly ellipsoid to ellipsoid occasionally elongate, hyaline. Ornamented with moderately crowded, amyloid verrucae and truncate spines, to 1 um high, single or in confluent groups of two or three, joined by moderately fine, low, amyloid ridges forming a partial reticulum. Suprahilar plage distinct, amyloid, flaking slightly, c. 2.75 x 2 um. Hilar appendix obconical, oblique, to 2 um long. (fig. 28b). The plage was distinct and amyloid, and in SEM appeared roughened at the edge. The ornamentation was type IIB. [Cooper:] Without lamellulae, with basal interveining. DCY visible in SV but natural yellow and not staining SV-ve, pigment not leaching. Cap pigment as flakes and not leaching in KOH. Some of the pilocystidia are very long and slender, to 200um, these perhaps not arising from spherical cells, like those nearer surface. Plage covered in violet amyloid spot. Spores length=6.4–8.1µm (µ=7.3, σ=0.4), width=5.3–6.8µm (µ=5.8, σ=0.4), Q=1.1–1.4µm (µ=1.26, σ=0.06), n=20. Ornamentation to 1um. This needs checking to see if pilocystidia are amyloid (like horakii ined.).
