Volvopluteus (Volvariella)

Thanks for the comments and voting feedback. You are correct about the pinkish gills (not just a shadow in the photos). I corrected my notes re: presence of a volva. I have never heard of the genus Volvopluteus… but just discovered this is apparently a synonym for the Volvariella speciosa. I checked the taste from a small piece and it was of raw vegetables/ radish – reminiscent of Pluteus cervinus.

Note that a volva and bulb are very different things…

In an amanita the volva is a covering of the entire fruiting body during early development (prior to expandsion of cap, stem, etc.) When an Amanita has a bulb (and several groups lack them), the bulb is a part of the stem that may or may not be clearly surrounded or surmounted by the volva or bits of it.


It looks like the gills are pink…

and that the pink shows through the wet caps. Am I interpreting the pictures correctly?
