I’d use the MO second level in the ID certainty adjective list.

I have to give some thought to the question about data collection. You certainly don’t want to do an end run around the mycologists running a study.

Taking notes (when possible) on a genus specific data collection form can be very helpful, but the priority of doing that during an ATBI is likely to depend on a triage process in which several minutes for note taking may be something that gets pushed down the list of action items when you come back from the field. Depends how the show is organized and what the rules are.

Very best,


Nice series of photographs

Dr. Tulloss,

Ah, I see what you mean. Looks like it. Do you think it informative/specific enough to call it A. japonica?

Well, in terms of the dried collection— for a number of reasons I couldn’t keep it myself BUT I was assisting a mycologist doing a diversity survey of the area who had permits/permissions—there is hope! He took the collection both as dried chunks and as a smaller quick-dried piece for later DNA analysis. I can shoot him an email to connect you two if you’d like, though he as just arrived back in Vienna so I don’t think he’s done any work on it yet.

Also, if you have any thoughts on how to contribute the most useful data when I can’t sequence or take collections between countries when traveling to study mycology—besides make my photos more informative and working with local mycologists when possible—I’d love to hear them.


The circle of white flesh on the bottom of the bulb indicates that there was some sort of…

extension to the stipe’s base that was lost duringcollecting.

I gather that there was no material retained in a herbarium. Is that correct?

Very best,

Dr. Tulloss,

I have a picture with the base of the collection visible, but there’s not much of a bulb. I also didn’t dig for a radical as I’m not terribly familiar with the group and didn’t realize that was a character. I’ll upload the picture I have in case it is informative.

As for A. japonica, I see it is hard to say without the radicle, though the bulb seems much more pronounced in the images on amanitaceae.org.

Thanks for the comments!

Do you have a photo that shows the base of the stem (the bulb and possibly a radical on the bulb?

Very best,

Rod Tulloss

Very nice set of photos, Alison.
