Ignorance, Herb.

Pure ignorance.

I don’t know enough to suggest how Amanita section Amanita might break down at the level of stirps in the gemmatoid and pantherionoid groups.

Work on taxonomy and phylogeny of section Amanita needs a lot of attention.

Very best,

Rod

I have in my herbarium a very large amanita in sect. Vaginatae.

It came to me without a photograph, but the written description says the cap is white. It was collected in the Black Hills and has very distinctive spores and very distinctive DNA (in the gene that was sequenced). I named the species provisionally (for the Black Hills). What little is known can be found here:

Have you ever seen something that fits the description?

I would love see photos of it and have more dried material to work with.

Very best,

Rod
