Thank you. That would be great. Please understand that I can’t respond in detail to more than a small number of specimens sent at the same time. Pictures can be posted on MO. Notes on the collecting site and the collection can be done on paper until www.amanitaceae.org provides a mechanism for on-line entry of field notes…which (we hope) is coming in the future.

Very best,


Thanks, Rod

I remember finding that big one. It was growing in a mulch-filled recess on top of a big boulder. It looked like it was part of the rock at first sight. It was more than twice the size of the others, which were nearby on the ground. I’ll make sure to save anything interesting for you in future!



They get brassy like this..

That’s what people call ’em. They get brassy like the big one when the cap surface dries out before it can pick up the staining reaction.

160 mm! That is a honkin’ big one. My notes say that I never recorded one with a diameter over 120 mm. To get into the mycological “record books” (if you are of the inclination), drying material with notes (e.g., cap diameter) and photographs produces a “product” that can be studied and recorded in the scientific literature (print and, nowadays, web).

Very best,
