Melanogaster aff tuberiformis

Beautiful images— I enjoy the black bellies and am working on the DNA of this group. It would be helpful to know the associated trees: oaks or conifers? In Sebastopol, if this is under oaks, it might more likely be in the euryspermus/natsii group. If it was under conifers, it could be in the tuberiformis group, which in North American might best be annotated: Melanogaster aff tuberiformis or cf tuberiformis (awaiting a formal name as M. tuberiformis is an European black belly).

I am new to Mush Obs, and would like to request an herbarium specimen to possibly include in our DNA analysis, although we are close to being done with our project— interested in Melanogasters from that area, especially under oaks in California— also Balsamia and Arcangeliella/Zelleromyces from under oaks…

nice spores, nice gleba…

nice find (and documentation), Darv!

Spores consistent with M. tuberiformis

as shown in Field Guide to North American Truffles by Matt Trappe, Frank Evans, and James Trappe. Same subglobose to globose sporocarp appearance.

This is edible, btw. Try a little of it (a very little bit goes a long way!) in cashew butter on celery sticks. Frank Evans produced this as a finger food for NATS several years ago. I’m afraid I consumed many of them.

You should have noticed a strong (becoming stronger within a day after digging it) aroma from the fungi. To me its somewhat fruity, very strong, but with a somewhat chemical aroma in the nose. When mature (and the gel inside the sporocarp becomes slightly liquidy) the aroma is stronger than most truffles.
