Specimen notes
Public Note:
milk white. Taste slightly bitter but not acrid. No reaction with KOH, NH4OH, Guiac, FeSO4. Gills with lamellulae, spotted red. Comes out in the non-umerensis group. Cheilocystidia with conspicuous needle-like extension, refringent, sometimes forked. Pleurocystidia occasional, thin, clylindrical and variable. Spores with incomplete reticulum length=6.5–7.2µm (µ=6.9, σ=0.21), width=6.0–7.0µm (µ=6.6, σ=0.30), Q=1.0–1.1µm (µ=1.05, σ=0.05), n=11. Ornamentation length=1.1–1.6µm (µ=1.3, σ=0.2). It would appear that the form of the cystidia is more reliable than the zebroid pattern of spores.
