Observation 139487: Tylopilus rubrobrunneus Mazzer & A.H. Sm.
When: 2013-07-08
No herbarium specimen

Notes: My first-hand description of KOH on the cap was “mustard green.” My wife also thought the color (KOH on cap) was greenish. She called is “olive.” But photo appears to show reddish tint. So I’m wondering about… individual perceptions of colors reported as “pink”, “amber”, or “green”, or maybe subtle variability in macrochemical reactions, or maybe just color as a function of photo depiction. Or maybe this type mushroom (presumably T. rubrobrunneus) produces subtly different KOH color reactions as a function of age, immediate habitat, or some other environmental influence.

I think these are T. rubrobrunneus. It’s only the KOH reaction that has me wondering. These are a common summertime occurrence in my yard.
