I collected CA phalloides yesterday with this sighting in mind…

here’s a link to my photo of a phalloides stipe and veil: it has a white apex and a yellowish (usually white) lower stipe, and just a hint of pale, cool, yellow-green color underneath the annulus (but only if lower stipe is also colored).


Compare to flavorubens here, with a yellowish stipe apex and a white lower stipe, also more brightly colored yellow underneath the annulus.

The middle mushroom in Nathan’s image has a metallic sheen to its yellowish with a hint of green cap…very reminescent of phalloides, but of course with important universal veil and volva differences.

So that’s what A. flavorubens feels like. I’d seen photos and read some descriptions, but there’s a gestalt I hadn’t been able to pick up.

this is an interesting case of eastern vs western eyes…

I also thought phalloides when I first looked at these photos…
but then, I couldn’t quite reconcile the brightness of that yellow cap on the right, and then darn it, the base of the volva didn’t look all that bulbous, plus the veil seemed kinda wrong.

Once I read the comments, i looked a bit harder, and saw that the underside of the annulus was also a bright yellow. you never see this in phalloides.

Nice process of learning to see the differences, tho.

Post your suggestion, Bob.

I think you’re right. I’ll vote for it.

A. flavorubens to me.

I’m not sure if this is something close to A. franchetii, A. phalloides or A. citrina. The first seems the most likely since I see some yellowish volval material on the youngest fruit body.
