I can look at this and at least confirm whether it is likely P. admirabilis or something different and send you some micrographs of anything worth looking at.
I will give you a mailing address.

Walt, that looks like a small Narceus americanus, not totally sure because the photo’s kinda dark. I’ve had a lot of success finding Gymnopilus luteus in areas that are infested with these millipedes. Maybe a coincidence, but I think there’s something to it.

Cat, they may be P. admirabilis, but I doubt it. P. admirabilis are usually a little larger and have a less pronounced and lighter colored wrinkly umbo. Every one of these looked the same out of the 3 flushes I observed last year.

I sent some dry specimens for microscopy last year but never heard back from the guy. I need a more reliable human to check this stuff out.

Interesting. What species is this? http://mushroomobserver.org/31483?q=19pP

Why not P. admirabilis? That species some times has an umbonate cap, and some times a darker spot in the center…. Granted, this one is rather accentuated, however I do not think that it rules that species out; not at all…
Or perhaps it is the substrate which is cause for doubt??

…eat vegetative matter I think. Yes on the nipples. Every one had a dark little nipple.

Very cool.

Millipede dung!?! Do millipedes eat wood?
Did they all have acute nipples like that, or is that one just cold?
