Possibly a sycamore associate!! (Never seen that before)
Update: Ochre spores suggest, just by induction, that it’s actually associated with the less-nearby Eucalyptus… despite growing pressed up against a sycamore root.
The placement of these two fruiting bodies around sycamore trees seems to suggest that, although there is a Eucalyptus maybe 30’ away across a cement walkway.
Growth in the middle of grass is very atypical IME. Perhaps this weirdness is not just a coincidence with the sycamore possibility.
Update: One is growing right up against an exposed root of a murdered sycamore! This doesn’t necessarily imply symbiosis, though… Pisolithus like to do this with cement too.

when comparing a recently dead tree, and a tree that has been dead for more than a year. As a mycorrhizal fungus, Pisolithus may grow into the rotting wood, which would act as a water reservoir. If the tree had been dead over a year, not likely it was still associated with a mycorrhizal species. Dr. James Trappe has suggested most mycorrhizal species die out within a year of tree death.
I’ve found Pisolithus around what appeared to be ancient Eucalyptus remains.
may fruit from apparently dead hosts up to a year after the tree was cut. I collected truffles from a row of trees Paul Bishop cut for a fire road the following year.
Let’s say “highly amputated”
I really hope to find more, further from Eucalyptus, to confirm the sycamore host.
There is a live sycamore shoot where the Pisolithus was found, sprouting from the root, I suppose. Proximity to sycamore indicates this is the likely symbiont for this fungus.
