Hi Debbie, yes, it was blue to my eye, but the flash really set it off – I guess there was some iridescence involved. It was more of a violet at the center of the cap, radiating out (mycena-like) towards blue, probably about 1/3 of the cap (visually). You are right about the ironwood, it was all over that park. Thanks for posting it. Best, Will

the observer also saw a blue centered cap in the field…

but it was intensified by the camera flash.

That is a rather bright blue color, centered on the cap, not a general wash of color from, say, adjacent sky colors.

I am not convinced that it is an artifact of light.

Sure wish that Will had collected it though.

not blue…

look at the sky in the second photo.
it is the lighting.

volvariella is another possibility

but sadly, the finder didn’t dig this up. It might be on buried wood/or not. the cap might’ve been viscid, what with that stuck debris. no sign of a volva that I can see. the rest of it could fit either species.

I don’t know of any blue capped Volvariellas either…do you?

Still…wish that I’d have found it! Love those blue shrooms.

you are too fast for me, Byrain! I clicked on the wrong images, had them up for maybe a minute, and you were ON IT!

Your ID guess of Coprinellus was correct, BTW.

The images vanished as I was proposing the name…
