Specimen notes
Public Note:
Cap grey/green & purple. Gill edge consistently purple. Gill colour E. Stem with strong purple-blood red fibrils which break up into coloured squamules against white background at stem apex. Cap edge not pectinate. Cap peeling 50%, leaving pale grey/purple layer underneath. Taste mild at first and then very hot. FeSO4 Pink, guaiac negative. Spore print not obtained. Spores with amyloid spot. Pleurocystidia thick walled (not all tho). Dark gill edge pigment weakly dextrinoid. Cap with thin filamentous DCY (they have refractive content in KOH so I'm calling them cystidia), SV-ve. I can find no evidence of McNabb's filamentous thin-walled cheilocystidia. They are thinner than the pleurocystidia, but thicker walled if anything. Spores length=8.5–9.6µm (µ=9.0, σ=0.4), width=7.8–8.8µm (µ=8.4, σ=0.4), Q=1.0–1.1µm (µ=1.1, σ=0.0), n=9.
