But I have never seen Fomitopsis pinicola sweat out of the top, let alone appear to be entirely covered in pore surface at that age.

In my experience, I have also never noticed the sweat to have any color.

When I tasted it, it was mildly acrid.

I don’t know what is up with this oddball.

why do polypores sweat…?

Polyporales or Polyporaceae

would be a better name to use if the genus is unknown. Polyporus is a genus of its own, and I’m not sure that this one belongs there.

is never this massive. Many polypores exude liquid when growing rapidly.

it can be quite pale, even mainly whitish, when young.

because ischnoderma is red.

What makes you think it’s not Ischnoderma resinosum?

on Maple?

Not known to fruit on Maple, at least in the west. The drops are common, but only on the pore surface on the Pacific Coast. I have never seen the yellow in this photo and the length of the cap is too long to stay white. It should have some color by now. I doubt it is Fomitopsis.

Great photo Jon…
