secondary infection

Regarding the orange on the exterior, I have observed Melanogaster covered with yellow Hypomyces (fooling some to think it might be Rhizopogon truncatus)— so this could be some kind of associated secondary infection…

Melanogaster tubriformis

seems correct for the sporocarps. I’m concerned about the photo showing black goo with orange, though. Unless this is a parasitic fungus growing from a Melanogaster, it is unknown to me. M. tuberiformis should have a reddish, rather indistinct peridium, which is often (usually?) covered with some soil. I have never seen any fungi growing from Melanogaster, but that doesn’t mean there isn’t one. I just don’t recognize that particular fungi, and it might be a separate species. Perhaps put it in a separate observation?
