A very pretty species

RET: YES, the characteristic I always notice about this one (besides the striking color) is the huge skirt on the stem. Reminds me of some of the giant partial veils that fall off many of the Lepidellas. Locals around the Telluride area know it’s an edible and collect them by the basketful. It’s funny to see because it’s so well known to them, yet hardly known at all to science. I can likely find specimens to dry and send to you, if you like, in the upcoming season.

The cap color of this species is variable.

From nearly orange to nearly white according to exposure to light and rain.

All the different cap colors that I have collected or have been sent to me seem to be genetically one species…so far.

The stem’s skirt is really big and part of the volva is often present in the form of a raggedy second skirt below the partial veil.


Nice to see an image of this on MO.
