and you can see that it is not so much a loss of color but a loss of the colored cap skin, the pileipelis! I have never noticed this myself before, but it does indeed seem as tho a driving rain might well beat the mushroom up enough to peel off the cap cuticle, and if the context is white, well, there ya go…so, rather than an rare and unusual pied mushroom, it’s just another miserably difficult to ID dark leptonia with marginate gills.

do this all the time after a soaking rain; it’s really tough to find good caps because they lose their color and scales.

nice detective work!

so, looks like color can be sometimes be incompletely deposited on a dark leptonia cap (pied effect), but YOUR mushroom also has marginate gills, so I wouldn’t say that it is necessarily the same species…

I was looking in MO and found this which appears similar.
I did see a completely dark colored one about 5 feet away.

I have a simular find (i’ll post it soon). Found it in oak/redwwod mix. Some where completley black other were black and whitish color. It seems the darker cuticle “chips off” to explose the white.

The specimens didn’t make the trip back in one peice for further study.

This is one of the more interesting finds I’ve seen posted here, I bet these have some quite interesting cheilocystidia with those marginate lamellae, find more and make a good collection if you can.

It looks as though it’s partly leucistic, or variegated!
