Observation 72957: Russula dissimulans Shaffer
When: 2011-07-30
No herbarium specimen

Notes: These mushrooms really surprised me. The general gestalt is Lactarius, but they produced no latex. Orange bruising is immediate and fades to blackish brown after several minutes. They were several inches across and growing under mixed hardwoods.

R. dissimulans is have thinner softer gills, more tightly packed, R. nigricans has wide spaced thick gills. Also the cap surface thickness is different, but that can be hard to see in the field. Also both should be first reddish staining, and have a mild taste, it might be a disgusting taste, but mild.

At least from the published descriptions, perhaps further molecular work will make all that meaningless.

This is the first time I’ve encountered the dissimilar Russula. This mushroom seems to straddle the boundary between Russula and Lactarius.
