Cross-veined Troop Mushroom - Xeromphalina kauffmanni
Unknown Cort - Cortinasius sp.
Maybe C. olearioides.
Purple-toothed Polypore - Trichaptum biforme
Dryad's Saddle - Polyporus squamosus
I'm a bit hesitant to put the name P. squamosus to this mushroom without a question mark behind it. It has almost all the features of P. squamosus: growth on stumps, large size, irregular outline, faint cucumbery smell, but is missing the "squamosus" part; the dark scales that are usually found on the surface. I read up on few other species of Polyporus, but none quite matched up. Then I re-read the description of P. squamosus at Mushroom Expert and learned that dark scales can wear off as the mushroom ages.
