Amanita smithiana sounds close on the descriptions I have been reading, I forgot to add that they were covered with a powdery substance in the notes. I’m going to do some preliminary microscopy today/tonight then dry it out. After that I’ll send it out to whoever thinks more work should be done.

Nice photos! Really show the species characteristics.

do dry a couple of these, especially the one that has opened up a bit and is probably producing spores. I know of no lepidellas here that smell like bleach….lots in the East do, though.

Halve the fruit bodies prior to drying them crispy dry, then you can split the collection between Rod and I, if you’d like!
