That seems like a good suggestion, Danny.

The two sets of photos seem very similar.

I only wish I could be more helpful.

Cristina Rodriguez, who is now in Texas and used to work with me, has examined in detail the material that Orson Miller called chyrsoleuca. She would be a good source to start with in terms of coming to grips with what you have if you find it again.

Very best,

Rod

Thank you, Rod

…for your helpful comment. If encountered again, I will produce a herbarium specimen. Best, Susanne

The comparison to 8742 is interesting. EDITED radically. 2014-03-23

8742 has a very distinctive and very persistent powdery universal veil. In that case the cap was so densely covered that it suggested to me the group of taxa including such Northern Hemishere species as Amanita farinosa in which the volva is bound to the cap’s skin well into the maturity of the fruiting body. The cap in these images (when examined at highest magnification) seems to have a similarly persisten powdery coating of volva. In this character, there is a similarity to A. chyrsoleuca; however, there is a problem.

That species name was originally applied to material from the Caribbean and was then misapplied to additional Caribbean material. There is similar (but morphologically distinct) material known from Panama. Because of the above, it strike me that Brazil will probably not have the Caribbean species. Nevertheless, It think it is useful to indicate similarity to the Caribbean species. If dried material is every available, I would be glad to help get it revised.

Very best,

Rod Tulloss

Unfortunately I do not have a spore print. At first sight I have assumed white spores. Is the picture (PC300868.jpg) misleading? I have doubts. Just posted another picture.
