A second effort at extracting nrITS allowed us to derive a fragment…

of a sequence. It is a good match to the sequences we’ve derived before from U.S. and Mexican sequences of Amanita macerisolum.

Very best,

Destroyed two incorrect comments. The best match is still prairiicola. However, we only have one gene to work with; so I think we need to keep the issue open.

Very best,


Meant to say that this is not a match for pruittii.

We failed to get an nrITS sequence.

So we can’t match to macerisolum, which has given us only nrITS. We got an nrLSU sequence that is a pretty darn good match for Amanita prairiicola. We also got less impressive matches to other non-mycorrhizal amanitas. I’m going to do a little more work on this one.

Very best,


Thanks Kevin,

This material has been received and accessioned to Rod’s herbarium. We have scheduled it for DNA sequencing.

A note about “sp-C13.”

We have had the good luck of being able to derive DNA sequences from several Collections of “sp-C13” are now known from southern California and from Baja California. It seems to be a good new species. We are going to go form a temporary code to a provisional name: Amanitamacerisolum”— the “Poor Soil Lepidella.” The seems to occur in dry (even desert) habitat with few or no apparent symbionts.

Its page on the WAO website is now


Very best,


Youre in luck

I did collect this (along with most stuff Ive seen recently) but didnt list a specimen b/c of the locality it came from. Im happy to ship off half of it to you if you dont mind paying the shipping, I can probably still send it off even if not…

I think that this could be Amanitasp-C13,” which is to be found here…

We have gotten some fragmentary DNA from older collections of this species, and would love to sequence a current sample (e.g., from the one you’re reporting). Is it possible to collect and dry this material? If you, if you would be so kind, I hope you might share a vertically split half or quarter of the fruiting body with the group here in New Jersey.

Very best,
