Polyporus epileucus. Fr.
This is quite a large and beautiful plant. It apparently grows without a stem, its color being an unequal gray. The pileus is somewhat coriaceous, firm, pulvinate, villous.
The pores are round, elongated, obtuse, entire, white.
This is not common with us, but I have met it a few times and always on elm logs or stumps.
