slower than usual staining was described as Amanita aestivalis. Dr. Pomerleau wrote a long time ago is his big book of the champignons of Quebec that he saw no taxnomic reasons for var. pallida of brunnescens. I have seen the pale citrine cap and the deep brown cap forms in a single fairy ring. And now we have some DNA evidence that pale capped and brown capped brunnescens are the same species. So I agree with what Dr. Pomerleau wrote more than 30 years ago. The evidence is piling up. The next question is whether A. aestivalis is really a separate species form A. brunnescens. It certainly has something different about the biochemistry, but it could be the same species.

I guess it’s a matter of time before someone will have evidence one way or the other.

Very best,
