Thanks, Darvin.

That explains a lot.

I think this observation more closely resembles Pisolithus. The peridioles visible through the peridium are hard to ignore. But the peridioles by themselves are not enough. The gleba still has a capillitium, which is not noticeable in Pisolithus.

So… where does that leave us? That annoying thick pseudostipe. Could it be that the sporocarp detaches itself to roll around like a Bovista, spreading spores wherever it goes?

Daniel, here’s a picture of the capillitium from MO

Arora says of Mycenastrum corium:

“Sterile Base rudimentary or absent, but mycelial fibers often present.” This obs. has a well-developed rooting pseudorhiza. There are fibrous mycelia at the base of the sporocarp, but they do not extend with the pseudostipe far below ground. Not Mycenastrum corium, at least as currently defined.

Dan says “Note the thick deep root filled with spore mass…” If the pseudorhiza/pseudostipe has “spore mass”, it is not visible to me when I view the original photo.

Arora says “Capillitium branched, thorny.” I’m not sure what that means to be honest. Is the spore mass prickly?

Might need to revert to mycroscopy on this, Dan M.

this looks like a job

Note the thick deep root filled with spore mass – this is not shared with other observations of Mycenastrum.

I did collect one specimen that I will be happy to send along to anyone who would like to have a closer look. These puffballs are pretty common in this desert, but almost nobody ever go’s out there, so I would not be surprised if the are not well known.

Radiigeria then.

Sagebrush can be mycorrhizal, but usually with endomycorrhizae, like Endogone. This looks nothing like Endogone. I’m wondering what it could be, Dan.

Host trees?

Sage brush is the closest thing to a tree for miles around.
