for the interesting comment. This tree is already dead, as are all the other trees I’ve found this species on so far.

Spread by bark beetles.

Looks like the tree pictured is nearing fatality. Bark beetles overwinter inside the cavity of Cryptoporus volvatus, and become well-coated with spores. Early in the spring they exit the fungus, and deposit their eggs (and spores) in nearby Pinus species, usually. The bark beetles begin creating galleries underneath the cambium layer, and if there are sufficient numbers, can girdle the tree below the bark layer and kill the tree. Thus Cryptoporus can be an indication of serious forest disease. Note the woodpecker holes: woodpeckers can hear the larvae moving underneath the bark, and are capable of capturing beetle larvae.
