So much for photo IDs!

Even tho the pores are a match (dammit) for Arora’s quercina photo, the brown staining and habitat preference have convinced me. And I know from variability; you guys have far more experience with this mushroom than I do; I concede the point. Thanks for taking it deeper.

I’m prety sure this is D. confragosa. The pores are way too small for Daedalea quercina. Moreover, D. confragosa is easliy identified by scratching the pore surface, and, just like Ganoderma applanatum, it turns from white to brown. Although the specimen is not scratched in this picture, it is bruised in a few places and heading toward brown. D. quercina never bruises or scratches brown at all. The pore surface of D. confragosa is enormously variable, ranging from regular pores to almost lamellate. PLus it does like birch a lot, which is what this appears to be growing on.

OK, you’ve got the experience…

…how do you justify your ID?

It’s a new mushroom for me, but it’s a perfect match for the quercina pore surface photo in MDM (and not at all like the sharp edged pores of confragosa also pictured), and Andy did ID the fruit body in hand in the field.

Pictures can be misleading but I still vote for confragosa…

…but if you look closely at the pore surface, the thick walls that separate the pores do indicate quercina rather than confragosa.
