Fungal specimens marked “dried and disinfected botanical material for scientific study only – no commercial value” get through to me in good order on a regular basis from all over the world. I foresee no problem with shipment.

Very best,


nice documentation Andrew.

it is an interesting mushroom: a cap color like phalloides, but a very odd partial veil and a weird basal annulus?

I’d call it a death cap for its color, but who knows what it’ll turn out to be?

Nice find.

Sorry, I didn’t save the specimen.

If you’re interested, I’ll pick some cute (but hard to ID) Amanita next year for identification and study. Is it legal to ship them?

Good question.

Could I see the dried material?

I am very interested to find out what species we have (possibly more than one) that we have been calling A. bisporigera.

Amanita virosa appears to be Eurasian.

Chinese researchers are finding multiple white destroying angels that are new taxa. It is probable that we also have more destroying angels than we are aware of in North America. For example, Amanita sp-O01 seems to be distinct from A. bisporigera.

I’m glad you checked the KOH reaction.

Your material may contribute to helping clear up the situation.

Very best,


It’s all mystery to me. Amanita bisporigera?

Kuo doesn’t even have A. virosa anymore…
Spore print white (cream?). Reacts to KOH (yellow)
