Lepidella v. Phalloides

I did give sect. Phalloides a consideration, too, given the color of the specimen (indeed rather unusual for sect. Lepidella). Obviously, I lack the proper training to discern the fine macroscopic properties corresponding to the two sections that are likely to nail the identity of this specimen. I went with Lepidella because of the first picture — what Rod saw as a limbate volva, I saw as a huge rooting bulb. If you look at the junction of the stipe and the bulb, i.e. the section where the stipe begins to flare out, the tissue smoothly transitions from the stipe cylinder to the “bulb” structure. Based on this “anatomical feature”, to me that structure looked like a well-defined bulb, rather than a robust volva.

So, some Phalloideae probably. I wonder what species.

I see some Amanita phalloides similarities, but am still learning to be able to more clearly see how similar vs. other Amanitas. Anyway, thank you very much.

P.S. Just thinking of the idea of eating it gives me anxiety!

The pileus seems to have pigment arranged…

in radial “fibrils” (“virgate pileus”)…similar to what seen in many toxic species of the Phalloideae. The volva appears to be limbate. There is a remanants of an extensively stretched volval patch on the pileus. The short gills appear to taper toward the stipe and not to be squarely cut off. From these characters, I’d say it is likely to belong in sect. Phalloideae.

Don’t eat this one, Sam.

Nothing substantial. A bit unpleasant, but no specifics to think of.

Did you
