and during the same time of the year, so maybe if we comb the woods we’ll get lucky. I’ll be scouting the area some in the meantime.

A techtab now exists for Amanitasp-WI01

Anyone finding this mushroom in the future is hereby solicited to send well-dried material with measurements of the fresh mushroom to RET.

I think this species may decay very rapidly; so relatively quick drying is critical…after making some basic measurements.

Very best,

you took away my “as if” vote…probably the only time I’ll ever get to use it.

Got it. Thank you gentlemen!

a big A bisporigera type…indeed it looks like Amanita sp-O01

Jon, I removed my vote regarding sp-O01…

so you could delete it if you wish to do so.

Maybe Britt can tell us which observation he was talking about.

Very best,

I’m sorry that I produced such a confusing comment. The sp-O01 was intended to apply to another recent post by Britt; however, the conversation got carried out on this page because I don’t know the number of the observation to which Britt refers. I saw the announcement of the posting, but did not view it before erasing the email. So Britt and I ended up discussing an observation other than the present one on this page. Confusing.

Very best,


No, I didn’t see them. Could you send me the MO observation number again, please?

For the bulky fall taxa that look like A. bisporigera, I would suggest the possibility of Amanita sp-O01, which was first sent to me by Walt Sturgeon, who has maintained it’s uniqueness for over two decades. Limited genetic work suggests Walt was correct. It’s a separate species.

We can’t yet segregate the white destroying angels. From available sequences we know there are several. But, on the whole, there’s not enough data. I know that multiple labs have explored this question; however, the data is either difficult to interpret (because of limited information posted with the sequences in GenBank) or lacking in some other way (e.g., insufficient notes taken by collectors on what was thought to be just another bisporigera.

Mea culpa.

Very best,


No problem. Did you see…

those big honkin’ white KOH + A bisporigera types? Any ideas?

Thanks again, Britt.

I see A sinicoflava several times each year…
By: Britt Bunyard (Fungi magazine) (bbunyard)

and the cap is always darker towards the disc, but you’re right, this is kind of kooky looking. Glad there was more than one specimen (often I encounter singletons). I’ll send them to you along with other items of interest. Best, B

The cap of A. sinicoflava is not zonate as in this entity.

This species is not familiar to me; and, if you should run across it again, I would very much like to review dried material of the specimen.

Very best,

Rod Tulloss
