A. fuscosuccinea?

Your observation seems to possibly be in the geographical range for A. fuscosuccinea. This species also grows on hardwoods like A. angiospermarum, which it is very similar to, but is more likely to have vinaceous or pink tones. They also differ microscopically in that A. fuscosuccinea has a distinct medullary zone.

is probably not Auricularia auricula of Europe. Mating compatibility of North American conifer and broadleaf host species has shown they can mate but are not really compatible. Google Auricularia americana and check out the following PDF article. In my immediate area this is not a common mushroom.

I saw two references for A. americana in the Index Fungorum. Both mention balsam fir as the host.
