Recognized by sight: The limbless volva and colored annulus are a better match than for A. multisquamosa. Also, the location where they were found makes A. morrisii a much more likely candidate.

Also, the partial veil seems to have been funnel-shaped…

Thanks for the insight

I’m sorry the specimens got mixed in your study, but I’m glad to have a more confident ID on this one. I’ve changed my vote as well. Thanks Rod!

The spores are also a match for mutlisquamosa.

So are the rather longish marginal striations.

I’m going to maximize my vote for mutlisquamosa.

Very best,

Rod

Hello, Eric. …EDITED….

Well, we got a surprise on this one. We had mixed up the printed herbarium labels on this collection and on the A. rasitabula that you sent us in the same package. Thinking that we were sampling the latter, we sampled the former. It really puzzled me that we sequenced a sample from a species in sect. Vaginatae and got a result that matched material labeled “multisquamosa” in GenBank…until I discovered the labeling error this morning.

I have not seen the material from which the supposed multisquamosa sequence in GenBank was derived; however, it is deposited in the NY Botanical Garden herbarium and could be checked. The images on this page are very similar in color to multisquamosa that I received from a NEMF collector in North Adams, Massachusetts many years ago. Peck’s original illustrations show much more brown on the cap (as in the caps in your pictures) than do many of the modern collections from the SE U.S. that are referred to multisquamosa.

I think we should certainly go with sect. Amanita for this material; and multisquamosa is quite likely. I’ll see if I can get any spores from this collection.

Very best,

Rod Tulloss

at this observation, the more I like Alan’s proposal of A. multisquamosa. It seems like a good fit in spite of the cap color being off. Maybe because it is fairly young material?

I guess you can see some minor striations on the margin in the pics.

I didn’t perceive these with the naked eye (and I looked). I still can’t see any as they’re sitting here on my desk. As they’ve started to dry, the annulus has turned a more pronounced gold color. The basal bulbs are turnip shaped. The cap color at maturity is a almost greenish gold color like I would expect to see on A. phalloides. Any more ideas? I find it hard to believe that this good sized, striking Amanita with somewhat distinctive features doesn’t have a name attached to it. Thanks.

I’m doubting A. multisquamosa

because there are no striations on the margin. There is no dark disk. The caps start out brown and are an even gold color at maturity.
