Amanita smithiana is in the same stirps with A. rhopalopus per Bas.

They share a large number of morphological characters including the deepling radicating bulb. These ladies lack that bulb; hence, I am suspicious enough to ask about the clamps. Bas’ stirps Rhopalopus is one of his clamp-bearing stirpes.

There are more than a few undescribed lepidellas from the West Coast that I haven’t gotten posted on WAO yet…and probably more that I know nothing about whatsoever. So there is a little room for thinking that what you have MO-observed might not have a name.

Very best,

Rod

any further than the spores. Do you think these could be something else?

Did it have clamp connections on the basidia?
