Observation 4070: Agaricus L.

When: 2007-09-14

Collection location: Lake Absarraca, Cheyenne, Wyoming, USA [Click for map]

Who: Barry Hammel (bhammel)

No specimen available

Growing in lawn grass at edge of the lake, by a road. Naively, I thought it was an easy one, didn’t notice any odor other than nicely mushroomy, nor know to watch for the color stain, which from the lower photo, on stem, looks brownish.

I don’t know much about mushrooms,but would love to learn to hunt “and find them”. I had a lot of these in my back yard. Not knowing if they were edible I left them for mother nature.I live outside of Laramie just behind a lake.Looks and sounds like this is it,but how can i be shore and if it is edible.

Doubt it’s A. campestris

It is certainly an Agaricus. However, A. campestris is pure white. This actually looks more like A. bisporus or one of the other red-staining Agaricus species. On the other hand, it may well be one of the yellow staining almond scented species. However, without confirming the staining reaction or at least have a description of the odor it will be essentially impossible to get to species.
