Observation 76153: Amanita sect. Phalloideae (Fr.) Singer
When: 2011-09-11
Herbarium specimen reported
0 Sequences

Notes:
At first I thought “submaculata”, on account of the well developed “ball gown” annulus, and the strong fruity odor. But the basal structure does not match submaculata. Also, the fruity odor had a somewhat medicinal component.

Fruit body was fragile. It fell apart upon harvesting. I think I got all of the stipe base out of the ground. Photo shows what I believe to be a reconstruction of the basal structure. Cap is non striate. Solitary specimen on a lawn under Shortleaf Pine.

This mushroom…

was found in the same area (1-2 acres of lawn with planted oak and (Scots?) pine) as each of these: obs 110858 obs 110856 obs 111234. I submitted dried material from these collections, but useful DNA data did not become available… probably because I had initially dried these in a south-facing window before finishing in my dehydrator unit. Apparently drying too slowly, or at too low a temperature, fails to preserve molecular data. I have since used my dehydrator to dry all material for study.

2012 seemed to be a banner year for Amanitas of this type(s) (latter part of September). I haven’t seen many (maybe not any) in this spot since that year. Hopefully, these will again become available.

My notes on the herbarium label say:

“smelled like steamed mussels in the exsiccatum.”

I wonder if this means that it has a garlic component in the odor? Since Amanita suballiacea is turning out to be much more common than any one had any idea it would be, I’m wondering if we are dealing a specimen of A. suballiacea that actually was garlicky.

Very best,

I remember collecting this one.

The mushroom was post-mature and not in the best of condition. I was a bit perplexed by the brassy color on the cap. Basal structure was weathered and seemed ambiguous to me.

Collected in a location where I later made collections of brassy-colored bisporigera types.

Thanks Dave,

This material has been accessioned to Rod’s herbarium.

It would be nice if someday we could…

get DNA from this specimen.

Very interesting. The stench at present is pretty much like a mixture of old bisporigera and steamed mussels or fish soup.

Not really pleasant at this stage.

Very best,

Rod
