that makes perfect sense, Rod.

Thanks for updating the lat./long., Ron

It fits your verbal description.


I’m pretty sure from previous experience, that vets think … (EDIT)

that the catalog of DNA sequences for fungi is as complete as the catalog for other organisms with which they have to deal. Hence, they are looking for a “fast” way to detect what the cause of the poisoning is without knowing the toxin…like diagnostics for viruses and animal parasites.

Hence, it’s a sensible thing to hope for; however, the hope is just a tad ahead of the reality. An isotype of aprica is now in the mail to Dr. Hughes at U. of Tenn., Knoxville. No DNA may be extractable from it, but maybe we’ll get something useful.

Dimitar has already sent one of his aprica sequences to Jan to help her with the vet.


and of course…

that is not to say that we don’t have some cryptic species within the “aprica group,” like the small, aprica-esque amanitas that are found regularly in the East Bay, in both Canyon and Huckleberry (essentially contiguous habitat), and also the quite orange-capped version of what we have been calling aprica. Now those would be interesting to DNA compare with the more “standard” form.

How would a sequence help with dog poisonings?

I thought that Jan was looking for a lab to check for toxins in aprica…specifically, whether they were the same or different from those found in muscaria. The poisoning symptoms from aprica are apparently quite similar to ibotenic acid poisonings.

Thanks for the collection, Ron.

I received it in good order.

Very best,


Yes I do

Hi Rod,

yes, I did get a good aprica sequence. I should load all of mine to GenBank, it’s just that I have been short on time and it is a kind of tedious. Let me know who should I send it to that might be interested. I am going out for the next 5-6 hours and will respond after that.

Best regards,

From your comment, I gather you have (a) sequence(s) from aprica.

Jan Lindgren is working with a vet in poisoning of a dog by A. aprica. They are thinking about a paper advising other vets of the incident.

One of the things they are looking for is a sequence for aprica. As you probably know, there is no such sequence posted on GenBank (as of last night, anyway). I’m sending off a piece of the isotype for sequencing today. But I expect I won’t have that back for a couple of weeks, and we may not (of course) get good data.

These are A. aprica. The ones I was showing on MT were autumnal species. A. aprica has interesting phylogeny too.

I see that I haven’t made an estimate of accuracy of the name. So I’ll vote “promising,” which is mostly what I vote when I have a high confidence and haven’t see the specimen(s).


what they are now?

Hi Ron:

They look like A. aprica, yes, but do you remain w/the same ID confidence after reading Dimitar’s post to MushroomTalk?

Thanks Rod,

These apricas that I find around Mt Shasta seem to have a brighter yellow color than those I’ve found further south, which usually have some reddish tints on them.

Nice pix, Ron.
