Observation 137545: Amanita multisquamosa Peck
When: 2013-06-24
No herbarium specimen

Notes: Near Spruce tree in grassy back yard in town, the Spruce had some muscaria growing near it too. Also saw my first Grisettes of the year here today too! It fits the macro descriptions.

Recognized by sight: I have encountered what I believe to be quite large (cap diameter up to 7 inches) specimens of A. multisquamosa. Some of my collections of this type have been under spruce.

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

where I have found this type. (It’s a good B. edulis producer :-) I’ll keep in mind to make collections of the panther types which I find there.

Interesting comment, David.

Perhaps, we should be paying special attention to the possible mycorrhizal associates of multisquamosa-like material.

If it is still in good condition, then I’d like to see it.

Delay before drying unfortunately can screw up both the micro-anatomy and the DNA in flesh fungi…certainly I can attest to the problem in Amanita.

Thanks for asking.

Very best,

I didn’t dry it yet…

, but I will and would be glad to send it along. Yes, I meant it had a striate margin.

Truncate short gills…

also points away from the rubescent group.

OK, Garrett.

Thanks for your quick response, Garrett.

It makes me look at the images at the highest level of magnification.

There is no question. You are quite right that this is NOT amerirubescens. No question. The cap margin is very strongly striate. (Perhaps you meant “striate” when you typed “marginate”?) The annulus was clearly funnel-shaped at first. That points to at least two taxa in sect. Amanita: A. velatipes and A. multisquamosa.

The length of the marginal striations and original coloring of the cap suggest that you have a very nice robust specimen of A. multisquamosa. I’m not sure if I have ever seen one so large, but Peck’s illustration of mutlisquamosa (although stylized) shows what appears to be a large specimen.

On the stipe base and the top of the bulb, the distribution of the volva in broken rings is more like what one would expect from muscaria var. alba than from multisquamosa; however, the originally funnel-like annulus is not something that I have ever seen in any of the muscaria-like group of amanitas.

I see that you did not dry and retain the specimen.

I would be very interested in seeing dried material of an apparent multisquamosa of the size you describe.

Again, thanks for posting and for your response to my questions.

Very best,

Rod

No blush today or any that I remember.

That’s funny I too see what you are seeing in the photos, but I don’t remember any blush what-so-ever yesterday. This was taken by someone else. The cap was mostly white with a tannish center. Today after sitting on my porch overnight there is no evidence of a blush. It’s now completely tan on the cap and maybe darker at the center, but maybe just the patches are more in shadow. It’s now much more the color of an amerirubescens without the red staining and no longer sticky it’s now shiny. It’s warts have also undergone the same color change. It’s darker where I handled it, showing my fingerprints but brown and only where it was handled. It’s not small It’s five inches across and seven inches high. It appears to have the roll at the base and the bulb is oval to the point where it broke from the ground so I would say it was very nearly rooted. The gills are truncate the cap is marginate.

I have the same impression with regard to the staining/bruising reaction.

Hello, Garrett,

I would suggest that you might check out

http://www.amanitaceae.org?Amanita+amerirubescens

and

http://www.amanitaceae.org?Amanita+rubescens+var.+alba

and, if the specimen is smaller than it looks, you might also consider

http://www.amanitaceae.org?Amanita+salmonescens

Very best,

Rod

that there is reddish staining on the center of the cap and at the stem base. Is that accurate?
