Agaricus sp.

I tend to agree with you re this species most probably being Agaricus campestris the field mushroom. However there are so many species in this genus it's can be a bit difficult to be 100% definite on the species identification from a photo. So I've been very conservative and just taken it to the genus Agaricus. Did you have any images showing or remember what the ring (annulus) on the stem looked like?

Hi Pam,
Thanks. No I don't have a photo of the annulus. I don't think I know what an annulus is. Are all of this genus edible?

The annulus or ring is found somewhere along the stem (stipe) below the gills and above the ground. These may in some species seem to be nothing more than a line around the stipe or at times a very pronounced skirt-like structure. Some are reasonablly robust whereas others are very fragile and fall off or are bumped off very easily leaving little or no trace of their having been there. With the Agaricus genus they tend to stay attached. If you look at the images in the species list of Agaricus sp, the image on the right will give you some idea of what to look for as will the image of Agaricus xanthodermis. Though be warned they are not always so obvious. Yes some of the species in this genus are edible. Though some can cause stomach upsets, A. xanthodermis being one of them. Do not eat any that stain yellow on any part of the fungus or have a chemical smell. If trying them only try a tiny bit at first to make sure you're not going to have a bad reaction to them. I don't talk about edibility as it is so easy to misidentity them. If you know anyone in the area that does harvest edible ones it would be worth your while to have a chat to tham.
