Observation 163107: Agaricus bitorquis (Quél.) Sacc.
When: 2014-04-08
No herbarium specimen

Notes: I found these mushrooms in a shopping center in the grass on one of the dividers. They were very dense and somewhat dry. They came out of the ground fairly easy and clean with just a little force. Rubbing it did not make it yellow at all. The cap of the one which is turned upside down was around 7cm long, and the smaller part was about 5cm long. The stalks on these are quite burly, and I’m not certain I smelled any sort of phenol, but I don’t know if I able to anyways. I tried keying it out, but I’m not satisfied with where I landed – either A. vaporarius or A. bisporus. I may have missed something in the keying.

Recognized by sight: another possibility that fits this agaricus. is there any red sating when rubbed repeatedly, or the stem is cut? If not, it is not bernardii.

After reading it, A. bernardi definitely could be a possibility. Any way to get a good id on it?
