I don’t know if mairei occurs with Cistus.

It’s cap is much browner in the material that I have seen including the watercolor paintings by Maire in the herbarium in Montpelier. I have a poor photogrraph of a Maire watercolor here:


The description on the technical tab at that URL is based on a combination of Foley’s original description and my study of original material of Foley, etc. Almost all the material was associated with Pinus. Maire has a watercolor of what is apparently the same species from Eucalyptus found in Egypt (if I remember correctly) in the early part of the 20th Century.

My problem is that I can’t give you a suggestion for an identification. I’m afraid that I’m off here in New Jersey just able to say what I know about the colors of the caps. That is not very satisfactory to me.

If you happen to have a chance to collect this mushroom some day in the future and have the time to dry it carefully and thoroughly, I would be glad to take a look at it.

Very best,

Rod Tulloss

Dr. Contu sent me material of A. cistetorum and a color illustration at about the time that the species was described. (See
< http://www.amanitaceae.org?Amanita+cistetorum >.)

Your material is very gray for a young specimen of cistetorum which is “lead gray” (actually this color seems very brown to me) until the mushroom ages to ashen gray.

It seems possible that you have found a Cistus associate that is a different species of Amanita.

Have you tried looking at the spores under a microscope?

The spores in the material Dr. Contu sent to me were often ellipsoid when viewed laterally. This characteristic might be of some use in determining your mushroom.

Very best,

Rod Tulloss
