Specimen notes
Public Note:
FeSO4 weakly green, Guaiac positive after a couple of minutes. Smell of shellfish. Gills F. cap color on gill edge near cap. Taste mild. Why not R. tricholomopsis? Micro-chars? Guiac reaction and other chars suggests this is not R. tricholomopsis- because it has thin-walled macrocystidia, green FeSO4. McNabb's spore size distinction is probably not a reliable character. (and umerensis). Whatever, this is topotype material. Gills dried grey. Sooty minutely speckled cap seems distinctive. DCY SV-ve, but has strong SV+granules, like tawai and umerensis. Some areas of cap exuding green pigment into SV. Cap with clearly delinetaed surface layer of spherical cells 200um thick. Cap has the hairs that are characteristic of the related group - griseoviolacea & tawai, but like tricholomopsis The cap hairs are in tufts. Cheilocystidia emergent from gill edge to 50um. Gill edge has thinner cytsidia mixed with usual macro-form. Cap hairs emerge from spherical base-cells. Lower part of hairs appears to be granulose. Plage weak and amyloid spot variable - hardly noticeable in some, but in other forming a violet flaking patch. Density and depth of ornamentation is variable, as is size (but from gill, not spore print). length=7.0–8.4µm (µ=7.4, σ=0.38), width=5.9–7.6µm (µ=6.7, σ=0.46), Q=1.0–1.2µm (µ=1.11, σ=0.05), n=20, ornamentation to 1.1um. Amyloidity of spines is patchy. Note that 9345 also has yellow gills and also shows green FeS04 recation.
