The material I have is from the La Malinche (or Malintzi) volcano in Tlaxcala edo. I when I have the time I will post pics and as much data as I can put together at this page in the new Amanitaceae site:


Very best,


Both varieties of flavoconia get red stains

When I was in Costa Rica, I noticed that several specimens of A. flavoconia var. inquinata would have a pink spot in the interior of the stipe’s base. I have seen this in A. flavoconia also.

More work needs to be done on this Mexican species. I have several collections of it, but I can’t remember whether I’ve done any microscopic work on it. I’ll check. If I have data, we’ll get it on-line at www.amanitaceae.org sometime in the future. It’s fine to bug me on this topic, although (with the current workload) I’m not sure whether I can speed up any further.

More later, if I find any data…

Very best,

There was a very slight red stain at the center of the base of stem in two of the mushrooms. It was really faint but definitely there.

I think I collected this in Mexico…

If I’m write, it didn’t stain like flavorubens although that name was used by some Mexican mycologists for this mushroom. I agree it is not a variety of A. flavoconia. It was often quite robust and was collected at rather high elevations…as you report.

Very best,


More robust

These mushrooms were consistantly more robust than the other collections we are calling Amanita flavoconia var. inquinata. Also the cap is a darker orange than the others.
