There is nothing here to indicate that this fungus does not have white spores, since cap color is not correlated strongly with spore color (unlike underside color, which at least can’t generally be pale at maturity for dark-spored mushrooms).

As for your suggestion of Hymenochaetaceae, why do I have the sneaking suspicion that if I had called this observation that, based solely on a dark cap color with no other data to rule out other dark-topped groups of polypores, that you would have marked that as “doubtful”?

Someone who is just “here for the facts” would not simultaneously claim that a fungus that was the spitting image of Bisporella citrina was as likely to be something else as that, because of knowing of some other species or two with somewhat similar field characters, while also claiming that a fungus that has a field character consistent with Hymenochaetaceae was very likely to be in Hymenochaetaceae, despite knowing of some other species with that field character … surely?

Polyporaceae is comprised of a limited group of polypores, all of which have white spore prints. There is nothing here to indicate that this fungus has white spores, particularly on account of the somewhat darker cap coloration, which is more indicative of the Hymenochaetaceae.

Don’t think it’s P. squamosus.

Probably not. I recognize dryad’s saddles on sight. They’re much larger, with scaly caps.

Maybe Polyporus squamosus?
