I just wanted to say “great find”, very interesting fungi.

don’t have the mass or size to build up in layers of fluffy clumps. more like a layer of extremely fine powder. Their trajectory from the hymenial layer should be some degree of discernible as well. If the surface on which it was found seemed like it was rotting, that might be a good indication.

Of course, assuming that K. deusta has white spores, the polypore itself can be ruled out as having birthed this mess on its surface, which doesn’t leave too many options other than a secondary fungus.

How can I tell whether the gray powdery stuff is mold or spores?

do we have a dual ID system yet?

if not, this should be split into two obs: 1 for the K. deusta and one for the mold, possibly Trichocomaceae.

If what gave you cause to suspect grey spores is the same grey we’re seeing here, and it was very finely powdery, I’d say it’s mold, but what the original fungus was is beyond me.
