information I was looking for. I did not collect a specimen at the time I made this observation, but I know exactly where it was found so may return for a specimen to examine microscopically. Thanks again for your informative and helpful response.

The first feature that strikes me is the vinaceous/roseous color of the basidiocarps. Your other option is A. americana, which does not typically get this color. The second feature is that you found this along the Mississippi river basin, which is dominated by this species, particularly in Tennessee, Arkansas, Mississippi, and Alabama. I have confirmed collections from southern Missouri, so it seems reasonable that you may have the species at its north-most range extent. To confirm this you would want to dry the basidiocarp and look at a paper-thin cross-section to see if it has a medulla (dense zone of hyphae in the center of the cross-section). Otherwise, it could be A. americana as these species can be extremely variable.

Brian, I’d be interested in knowing what features

you identified in my photos to determine the species of these specimens. I’m always looking for tips on how to refine my identification of the mushrooms observations I post. Thanks a lot for looking at my observation. Appreciate your help.
