many fungi enjoy a “casing” layer when fruiting. This layer helps hold in water, sometimes nutrients, and can retain heat as well.

I’d think either oak or hickory (or many other tree species) could have been present, Sarah. Pisolithus is known to associate with 35 tree and shrub species.

Just wanted eucalytpus away from the observation, as that tree species has several other possible Pisolithus species hosts, probably imported from other locations in the world.

I’m inclined to say oak.

I can double-check, Daniel. Lots of oak and hickory in this area. What do you think of the kitty litter substrate?

And thank you, Debbie!

Definately Pisolithus, Sarah.

The only question now is, what was the host tree which was probably nearby?

nice documentation.
