Question about this species?
By: Ann and Rob Simpson

We found a fungus that looked like a Cryptoporus on a tree but it was larger, and was very cold to the touch, considerably colder than the ambient temperature. It appeared like a white amorphous mass with no pores evident – it was not hard to the touch like the above fungus. Does this species ever feel cold (maybe when it is immature)? Thanks – Ann and Rob Simpson

Tyromyces leucospongia is not a valid name for this species as per my original comments. However, the question of Oligoporus versus Postia versus Spongiporus for this species turns out to be complicated on both nomenclatural and taxonomic grounds. Therefore, it would seem Oligoporus leucospongia should be the preferred name until this issue is resolved. However, I would treat Postia leucospongia and Spongiporus leucospongia as non-depricated synonyms until those issues are resolved.

This is not a good name for this species

Please see my comments at Oligoporus leucospongia, Tyromyces leucospongia, Tyromyces, and Oligoporus. There is only one species in California (and possibly anywhere) that is properly called Tyromyces. As to the other names, which is valid and takes priority is complicated. Still researching that part.
