Observation 185969: Carbomyces Gilkey
When: 2014-10-26

Notes: In leaf litter under Juniperus monosperma. This had been dug up by some rodent (note teeth marks) and left for us as a gift. There were many digs but no leftover truffles to be found. This smells strongly spermatic. The scope available is without a reticle, but just guessing I’d say they were 8-12μ, round, smooth, the center appearing as if it was composed of numerous BBs.

thanks, Bob. PS: Alex Weir says hello :)

Why? I cheated. I sent it to Ali Mujic. He identified it.

It really shouldn’t have been that hard. I believe Carbomyces is our (USA) only desert truffle. I should have recognized it as we find these from time to time in New Mexico, but they are always old dried specimens, never immature like this. I’ve only found C. emergens, as it is the only “common” one, but this my turn out to be C. gilbersonii, only know from the Type and those found a few years ago by Moreno etal.

Why do you think these are Carbomyces

and not Tuber?

Asci were observed

Nunerous asci comtaining eight spores were seen. I should have mentioned that. I was having a very confusing day.

Most Basidiomyceota hypogeous fungi are loculate.

They have small chambers in the gleba.

Most Ascomycta hypogeous fungi don’t.

I can’t see any chambers in this obs.

why not…

Basidiomycetes?

Thanks, looked for a way to edit observation

my comments were directed towards your notes.

I’m currently trying to find Ascos mycorrhizal with Juniperus monosperma, hoping for a hit.

I made a mistake and described the microscopy of another fungus.

More or less round about 25mm, no latex.

Several questions, Bob.

How large would you say the fungus is? Height? Width?

Was there any latex when opened?

Maybe I’m reading something into your description, but could “with small rounded tip spines” be construed as short peglike protrusions?

“…very noticeable germ pore” Is this the same as a basal color?

Oops, wrong fungus

Discription should have read:

Sorry
