under study in North America. Any chance that you could collect and dry some of this species? The very pale, straw-colored cap suggests that this material might be the species we’re calling Amanitasp-lavendula03.” This is very likely to be the same thing as a taxon named from the northern midwest of the U.S. (Michigan) in the 1930’s (A. brunnescens var. straminea). The entity was photographed by Alexander Smith who collected the type material. The name is due to a French mycologist, E.-J. Gilbert, who apparently did not know brunnescens very well.

At any rate, we have the opportunity this fall to scan MO for material that is
citrina-like and ask for dried material for microscopic and genetic study in the coming months. It’s a neat project and will sort out some names that (we have discovered) are being mis-used. Some name corrections will be required.

If you’d like to help by sending us some specimens of this citrina-like collections and placing their mug shots on MO, we will gladly make use of the material in our studies.

Very best,
