Specimen notes
Public Note:
spotted brown, gills anastomising near stem, basally interveined. Stem with indistinct vinaecous ridges. Cap umbilicate, dry, ridged at margin, cap skin not extending around edge. On stem base FeSO4 salmon pink, guaiac no reaction. Gills vinaceous buff. Gills and flesh mild. No smell. NH4OH on cap and tissue no reaction. KOH on cap orange/reddish/brown. Spore print A - bright white. Pat suggests n.z. but that seems more yellow Without DCY in Sulphovanillin. Keys close to cremeochracea. To Pat 11/1/2010. [Leonard] This is R. griseostipitata. The grey in the stipe cannot be seen in the field photo because of the flash but is clearer in the lab photo. The ellipsoid spores with quite a high Q seem to be distinctive in this species. [JAC2010] cap cystidia short, often forked, like 'atroviridis'. No cheilocystidia. Pleurocystidia very infrequent, thin-walled. Spores are elongate compared to other species, and with distinct plage length=6.7–8.2µm (µ=7.4, σ=0.5), width=5.1–6.0µm (µ=5.5, σ=0.3), Q=1.2–1.5µm (µ=1.3, σ=0.1), n=15. Note that standard deviation of Q is generally much lower than either length or width (providing Q is aggregated per spore, which it generally isn't. Material with Pat 20/1/2011, Returned Feb, reconfirmed as griseostipitata. However sequences place closer to Pat's subvinosa. Differences are that R.g should have discoloring flesh, R.s. has reticulate spores, spores bigger etc. This brings into question identity of PDD77754 & PDD89079. Sequnces place R. griseostipitata and R. griseoviridis in the virescens-crustosa complex, and shoud have similar hairs.
