Observation 168466: Tuberales sensu lato

Small round-ish shaped fungi, found under forest debris, when checking another fungi very close by. This small fungi did appear to have a very short stipe, but broke away when I examined the specimen in the soil. In one of the images I have indicated where I think the stipe was in relation to the fungi body. I bisected the specimen and there are clear indications that the inner area has fungi like chambers, and a central growth in the centre which traverses the complete area of the fungi.. The specimen when cut had no discerning aroma. There is some insect damage showing on the outer body of the fungi?

When fresh the fungi had an Earthy smell. Nothing really strong. Now dried specimen has the common Mushroom smell we are all familiar with. I am going to try and do some micrographs this evening …so will see what eventuates. I will keep you posted if worthwhile. Chow, kk

Did you notice any odor from it after drying?

If it is Macowanites, it might have an odor, which is important to know now when it is fresh.


I have dried and stored the specimen. It is available from me at any time.

By the way,

the “insect damage” is an animal feeding on it. Could be slug, or could be a marsupial. Most of the really rare marsupials in Australia consume hypogeous fungi.

Similar to Cystangium, Ian.

The stem-like structure in the center of the fungus is exactly that. When internalized, it is called a either a pseudostipe or columella. A columella tends to branch like a tree trunk, which this does not. I’d probably call it a pseudostipe.

Probably related to Russula mushrooms. Has similarities to Arcangeliella and Macowanites, but more completely hypogeous. Both Arcaneliella and Macowanites usually show a portion of the convoluted gills somewhere on the peridium (outer surface). This seems completely enclosed (but check your specimen carefully).

Needs to be conserved, Ian. I don’t know if anything like this has been confirmed from Australia. Need to document nearby trees and shrubs, too. One of them is likely the host for this species.
