Sigh, seems I’ve got another wrong. I detect no odor, and since Arora and rogersmushrooms.com claim A. bitorquis can stain faintly pink or reddish, I went with that. However, the community consensus seems to go with “pink means A. bernardii”. So be it. Too bad I don’t have a dehydrator to keep these for later.

Summary: Agaricus bernardii

The red staining (even weak) and the pointed base are typical of A. bernardii. A. bitorquis should never stain.
