Sorry, apparently the base of the stem really likes it in the ground as both of them broke off when plucked :( When I see another one, I’ll dig it out more carefully :)

I found that var. pallida was…

missing from the list of synonyms on the WAO brunnescens page’s techtab. That’s fixed. I also re-edited the MO name page for var. palllida.

I think that this could be A. brunnescens, but without the bulb…

we really can’t tell.

Pomerleau felt that distinguishing a variety pallida was not “taxonomically significant.” I have found pale caps, brown caps, and half-pale/half-brown caps in a single fairy ring; and this has led me to believe that there is not much use in distinguishing Krieger’s variety.

For the moment, the very slowly staining A. aestivalis is still separated from brunnescens by me. Only the very center of the pileus can be yellow; all else is truly white without any citrin tint. Singer mentions that A. aestivalis stains much more slowly than does brunnescens; and that seems to hold up from my observations.

Your photographs show a brown disc on the cap; so I think that aestivalis is not a possible determination in this case.

Very best,

Rod
