Fascinating finds all, kc! RE the Elaphomyces, evidently at least one
general division of this genera, E. muricatus, has adapted by rodent
predation primarily of the peridium by including small clumps of spores
imbedded within the peridium! Thus even nibbling on the outside of the
truffle give the roden considerable spore ingestion and ensures the
continuation (and dispersal) of the fungus. Many Elaphomyces I have
found predated on have broken into the gleba at least a little bit. Even
that is enough spores ingestion to ensure thousands of spores per
"pooparoonie" as Chris Maser likes to call fecal pellets.

I was especially interested to learn of Cryptoporus on hemlock. I have
come across this interesting beetle-spread fungus before, but almost
exclusively on true fir. Hmmm. Maybe that's a good way to control true
firs in Ponderosa pine stands...
