What is this?

[Kveldssanger]

On a stump (not sure what species - looked to be ring-porous, though other trees in the area are cherry and poplar only). Initial thoughts were D. quercina, as the growths are on a heavily-decayed stump, the growths are also atop the stump, and the the morpohology and clustered presence is suggestive of the fungus. However, the tube layer is not deep enough when a cross-section is taken, the pore layer isn't 'maze-y' enough in places (and the pores are also too small?), and the flesh colour is a little too rustic (?). The colouration is also a little too grey perhaps, as usually there's more of a brown-biege-purple tinge. It looks like a brown rot as well, as the wood is still tough and seemingly dry. This would fit with D. quercina, of course, assuming it is a brown rot.

Any assistance here would be appreciated!

Note: Considered Pseudoinonotus dryadeus, though it was too soft and moist for this time of year. In my experience, it usually dries out markedly very quickly, and even if it remains whitish it's far more 'crusty'. Here, the flesh was still moist. However, other characteristics probably fit this fungus.

Is it not Phaeolus? Brown rot, presumably conifer stump.

[Kveldssanger]

Phaeolus would have been more crumbled, and had a brown colouration atop, no? Bit like this, from a douglas fir I found. I don't think this'd be a conifer stump, as there's no indication of any other conifers about. It's by some flats, so would have been an 'amenity' tree.

Well I'm stumped ah ha ha ha ha....

Punbelievable!

 

Wondering why David isn't all over this thread like a bee to a can of opened pepsi!

Oh I'm all over it, just letting your nose lead you down the Id alley

 

I had no internet last night, but have been comparing your flesh and pore layer shots against a couple of suspects this evening.

I have a hunch.

I went through every polypore in the Phillips book, and really struggled to find anything beyond oak mazegill (D. quercina) and oak dryad (P. dryadeus). They're too big to be blushing bracket (D. confragosa) and aren't blushing, and they cannot be a Trametes as the flesh is not white. Flesh isn't right for Abortiporus biennis. For me, the flesh colour isn't matching up to anything (asides from oak dryad), and not knowing what the host tree species is that has thrown me as well.

 

If need be I can get more shots, as there's an abundance of sporophores on that stump.

 

Is it a common one we're looking at here, do you think?

[Kveldssanger]

Any updates on your hunches, David?
