Looks like subrufescens…

is a good possibility here.

Hi Dave, there is a ring

I noted it in the description but failed to post a photo that showed it. Just added some new photos that clearly show it.


Lack of a ring on the stalk…

fails to support Agaricus subrufescens. Otherwise, the resemblance to A. augustus would point toward subrufescens. Augustus is reported as generally growing near conifers.

Thanks Dave

that’s what I thought when I went back to look at this obs. Any ideas on species? The cap has the scaly yellowish coloration and marshmellow shape of A. augustus but seems small and maybe it doesn’t occur in Arkansas?


I would call these gills “free.”

Look at the cross-sectioned mushroom in zoom mode. The nicely rounded ends of the gills curl up to meet the cap context a few millimeters shy of the stipe. This is pretty good evidence that the gills have not merely torn away from a previous attachment.
