Observation 104211: Tylopilus rubrobrunneus Mazzer & A.H. Sm.

When: 2012-08-06

Collection location: Ricketts Glen State Park, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

Found along the Falls Trail in Rickett’s Glen.

I find this (and have finally arrived at an ID!) every summer along a wood border in my front yard. The KOH color change on the cap really had me wondering… B/R/B reports that purple areas “bleach pinkish brown.” One specimen from my yard showed a cap KOH change to mustard yellow/green. I took a specimen along with me to NEMF, we dropped a bit of KOH onto the cap, and initially the purple color did appear to fade/bleach. But after a couple minutes, I percieved the mustard color, most apparent when viewed in natural light. I asked a few other people for their opinion, and got a range of responses… “yellow”, “brown”…

The specimen seen here exhibited the same cap KOH change from natural purple to faded tannish brown then, within one minute, the mustard.

Stipe without reticulations. I’m not getting the olive bruise/stain on the stipe.
