Observation 119038: Amanita phalloides (Fr.) Link
When: 2012-12-04
Herbarium specimen reported
0 Sequences

Notes:
This unfortunately lone specimen was found near a lone Live Oak among Bishop Pine.
Cap was 6.9 cm across.
The white spores were amyloid.
Spores were ~ 8.2-11.0 X 6.2-8.2 microns.
Q(ave) = 1.25 (16 measurements).
Since the specimen was somewhat aged and fallen over when I found it, I can’t be 100 % sure that there wasn’t any kind of annulus present.

Recognized by sight: The base of the stem could be from section Phalloideae. Cap margin not striate.
Based on microscopic features: Spore size matches, amyloid
-61% (3)
Recognized by sight: Base of the stem doesn’t look like section Validae. The texture of the top of the cap points in that direction however.
Based on microscopic features: Spore size matches, amyloid

Yes, what I meant was

the cap texture seemed drier and the whole mushroom had a more solid feel than the typical A. phalloides….or almost any Amanita I’ve been finding under the present conditions. Every phalloides, calyptroderma and franchetii that I’ve run across in the last few days are moist and/or waterlogged and falling apart when handled.

do you mean the cap texture?

what did it smell like?

you could always put it into the DNA pile!

w/out question it is in section phalloides (w/that bulb and saccate volva and the rounded, amyloid spores). the cap warts are weird, but that could be due to any number of environmental influences.

the stem is usually solid in a phalloides…what do you mean?

cool find, whatever its eventual ID.

Well, I can’t disagree about this

probably being a phalloides. It didn’t feel or smell like a phalloides and the stem was mostly solid. However, it was growing in a spot were I have previously found A. phalloides.

that is one weird phalloides!!!

not just the cap color, which of course is often variable, but the oddly textured cap, almost warted.

This is obviously in section phalloides, and almost certainly a phalloides as well, just with a UV that happened to break apart on the cap rather than cleanly tear.

The inherently striate cap itself (not the cap margin) also speaks to phalloides being the correct ID.

Too bad you didn’t have your tricorder along, though, Ron…this one would be interesting for a DNA confirmation.

I’ll bet there was an annulus.

The spore measurements are a pretty good match for A. phalloides. The average Q is practically right on the money (as things like averages go) for the average of all the phalloides spores that I’ve measured. It’s dark, but the pigmentation pattern is consistent with phalloides. I have a picture of a dark phalloides from the east coast on the WAO taxon page for phalloides.

Very best,

Rod
