Of course.

Bob, may I use your photo on the web site?

what dimension is represented by their length?

Very best,


Forgot to mention…

there are morphological characters distinguishing this species from populiphila: This species has ellipsoid spores as opposed to subglobose ones (a rather dramatic difference) and, apparently, the present species has a more robust fruiting body.

Very best,


We received an nrITS sequence for this species in the last batch.

We have a good clean sequence that is a very good match to the sequence we have from South Dakota material that was at first thought to be populiphila, but turned out to be distinct from that species genetically. We’ll need to do some more work, but the gene sequence is a match for that of A.pahasapaensis” (meaning “Black Hills”) from…the Black Hills.

This collections should really enrich what we know about the species. No data on Bob’s collection has been added yet. This looks like the place where it will be added:

Very best,


it would be great…

if you guys could do a quick spore check on this one. My money is still on section Caesarea: no bulb, hollow stipe, striate margin, membrane UV.

If not you, then who? ;)

Thanks Bob,

This material has been received and accessioned into Rod’s herbarium.

Just crossed my mind….

There are a few species with pink gills in sect. Caesareae. One is Amanita roseolamellata that Lucy Albertella has repeatedly posted on MO (from New South Wales, Australia). The remainder are distributed in eastern and southeastern Asia and in eastern North America (e.g., A. ristichii).

Very best,


Gills drying pink is common in some groups within sect. Vaginatae.

again with those gills drying pink!

I have seen this is some sp. of lepidella here in the west, but never a caesar.
Dang it man, you sure find the most amazing amanitas.

Rod — Didn’t say “no annulus”, but I don’t see one either. I thought it was our pantherina ‘lite’ until I dug it up and so no veil.

Debbie — Yup, hollow. A white caesaria would be cool. I’ll see if I can fit one in next week. I’ll be in the Chiricahuas and anything is possible there.

Note: The gills dry pink, if that’s of any significance.

Bob, what did you mean by “no annulus”?
By: R. E. Tulloss (ret)

Were you asking for an opinion? If so, the horizontal marking on the stem is from a break in the stem surface resulting in a large recurve scale. I don’t see evidence of a partial veil.

Very best,


bet it has…

a hollow stipe.

Amanita tuza??? in NM?

Sure resembles a white casesar. but which white caesar…

Thanks for the cm scale, Bob.
