Specimen notes
Public Note:
pink cap edge distinctive (really pink under cap skin). Taste mild (acidic?), stem immediately salmon pink/tan with FeSO4, gills F, spore print G-H. Pat - atroviridis? Need image of spores. Keys to tricholomopsis and not griseoviolacea, but doesn’t look like R. t.? SV-ve, but cystidia red and visible (not seen this reaction before). Cuticle a 250um layer, disorganised, dendroid-branched, with erect external hyphae but not forming a palisade. Underneath that a mixed layers with nests of sphaerocysts connected by intermixed filaments. Stem cuticle filamentous, parallel, over sphaerocysts, no refractive elements seen (caulocystidia).Cap hairs are broadened, septate, narrowing towards apex but rounded apex, to 200um long, not arising from swollen cells, sometimes strongly attenuated at base, sometimes forked at base, tortuose. Cheilomacrocystidia protruding to 30um on unsquashed gill, not especailly different on gill edge and face, slightly thick-walled, uniformly refractive, acuminate and not capitate or strangulated. Spores with grey amyloid spot. Microscopically close to griseoviolacea and atroviridis. Spores length=7.9–9.6µm (µ=8.7, σ=0.54), width=6.9–8.8µm (µ=7.6, σ=0.54), Q=1.0–1.3µm (µ=1.15, σ=0.06), n=20, ornamentation to 1.3um. Sequence close to R.olivacea - subgenus Russula, section polychromae, subsection olivaceinae. R. olivacea has spinose spores, black reaction with phenol, yellow spores, and is toxic.
