Observation 165262: Agaricus bernardi Quél.
When: 2014-05-14
No herbarium specimen

Notes: I’ve never seen a grocery store mushroom stain red, so I had to post this. Based on the keys I looked at, few agaricus species stain red and have no NaOH (KOH) reaction. It also has a pretty enlarged base. Was growing in mulch in a flowerbed. Inrolled margin.


Found another specimen 5/28. Scalier than the first couple.
Found again 6/20.
Found again 6/20.

I didn’t realize so many agaricus in this country, especially the East Coast, are undescribed. :)
