Observation 77827: Amanita sect. Lepidella sensu Bas
When: 2011-10-02
Herbarium specimen reported

Notes: UnID’ed Amanita sp. sect. Lepidella. Several found among Hemlocks on Oct 1, 2011; smell and look says Lepidella. Others found also. Basal bulb didn’t seem large enough for A abrupta; not enough stuff going on on the stem for A cokeri. So, unsure as to spp. Not rooting really at all on any of them, either.

I agree with lepidella as a group…

and Britt’s amanita sure resembles this abrupta collected by Dan Molter:

Into the mix…

Amanita citrina, A. brunnescens, and species similar to those two entities have been recognized to be in section Validae for a number of years. The change was triggered by molecular results and was quickly adapted by morphologically oriented folks studying Amanita. Within the Validae, according to the most recent results, the citrina “group” is basal or nearly so. Hence, the marshmallow bulb may represent a trait inherited from an ancestor that is also an ancestor of some taxa within the Phalloideae. I’d certainly take that on as a hypothesis to be tested.

Because of the volval structure in the citrina “group,” it’s very unlikely to get Lepidella-like warts on the caps in that group. I wish we could see under the partial veil. The idea that we might be looking at an aging specimen of A. abrupta with a bulb that is a little more inflated than usual is something that I haven’t been able to shake. If there were fibrils connecting the underside of the partial veil to the stem, then that would be evidence for a determination of A. abrupta. Amanita abrupta rather commonly has a few vertical splits in its bulb and can be very small, almost as small and gracile as a Mycena. On the other hand, I don’t feel completely comfortable proposing A. abrupta as in any way a definitive determination.

Do others agree that there seems to be quite a bit of flocculence around the base of the stipe at the beginning of the bulb? If so, this would be another character that would not be found in either sect. Validae or sect. Phalloideae.

I’m hanging on to the idea that this entity belongs in sect. Lepidella…probably in subsect. Solitariae Bas.

At the moment, I doubt that we will get to a definitive solution in this case.

Very best,

R.

Smells of a smelly smell

DV: smell on all the specimens, young and old, was smelly which I felt to be of Lepidellas (like old ham to me).

Walt: we found tons of obvious A citrina…so I guess you could be right. The bulb is correct; just some seemed so floccose on top of the cap and really looked like Lepidellas. We also found lots of A bisporigera too. That A citrina is in the same section always throws me. I’ll defer to you and presume them to be less colored citrinas. Case closed (for now).

Amanita citrina to me with that marshmallow bulb.

that’s a little amanita, for a lepidella.

did it smell like chlorine or…?

Hand-sized

Deb: I’m pretty familiar with A polypyramis as I see it every year (lots) in the SE and they’re pretty big. I find those to have very friable veil, warts and all…leave powder all over the ground. The one pictured was the chunkiest of the litter, about hand-sized. The rest had smaller caps but longer more slender stipes and bulbs. Also, I’ve never seen any A polypyramis with Pseudotsuga. In fact, I cannot think of much that’s mycorrhizal with that tree. The really notable character on this one, for me was that the basal bulb was not very notable…not really big, not rooting, though I do see some clefts on it and the others.

size and odor?

marginate globose bulb could make it polypyramis (or something similar)…although that species range is more SE.

you are too quick, Britt…

I was just about to make a sarcastic remark about salt collecting at the Great Lakes!

Must be dreaming about California already, eh? ;)
