Ill send you the whole spore print. Im done with it, In time if I hung on to it I would loose it. I made a slide of the spores and I scraped some of them onto PDS agar, (Something I do with a lot of the mushrooms I find. Some times it grows but usually not.)
Do I just send it to the address listed on MO? Ill try and get it out tomorrow.
Thanks for all your input Eddee

You’re correct.

Amanita magniverructa is known largely from California.

Could you send me a small piece of the spore print? I’m curious to see the spores. I have seen large bulky amanitas before and have never been satisfied that I could identify them. One possibility would be Amanita spissa var. alba Coker. But there could be several others as well. Unfortunately the only thing in the type collection is a spore print…and, if I remember correctly, these were difficult to reinflate by the time that Dr. Jenkins and I (separately) saw them.

Very best,


now that I have done some research

I don;t think A.maniverucata is on the east. I read its only a West Coast species. What confuses me are the very large almost pyramid shaped patches on the cap. I took a spore print white of course but the spores are very round.
Thanks for the input. Eddee

I don’t think it can be magniverrucata, Eddee.

In that species, the volva and the cap flesh are connected without an intervening skin and the cracking of the cap at the bases of the thick warts make them look even thicker than they are.

In the present case, the warts are definitely separated from the cap (with their edges turned up), and it seems very much that there is a skin on the cap.

I am not at all sure what the mushroom is, but I’d guess it has amyloid spores and belongs either in section Validae or section Lepidella.

The mushrooms seems to be a little the worse for wear. There must be a lot of very watersoaked mushrooms out there if your weather has been anything like what we’ve had this year in New Jersey.

Very best,
