Interestingly, the closest BLAST match is 97%, from the holotype of Amanita ibotengutake, a toxic species described from Japan.
of claims that this newly described PNW species occurs in the Sierra, before we get actual DNA confirmation.
Jan Lindgren asked me to keep an eye out for this in the Sierra several years ago.
Macromorph matches are not enough!
Micro matches are a good start (see Pastorino’s observation of this purported species), but again, I think it necessary to confirm with DNA.
