Observation 3675: Agaricus arvensis Schaeff.

When: 2005-09-25

Collection location: Elgin Co., Ontario, Canada [Click for map]

Who: Rex (Rex Bartlett)

No specimen available

Found growing in large arcs or fairy rings in grassy areas in my region, A. arvensis is commonly overlooked by the average person as being a “toadstool”.
One defining characteristic that I often use is the patchwork on the veil. Observing the underside, you will quickly notice the patches resembling a cog or gear. I enjoy collecting this mushroom as some of my friends who will not eat a chanterelle for instance will eat A. arvensis because they are already familiar with the cultivated A. bisporus.
Older collectors do not differentiate between A. arvensis & A. campestris, referring to both species as “pink bottoms”.
The common name I use the “horse mushroom”.
