Description: Original observation #129223 (Mushroom Observer)
Occurrence Remarks: These were growing bracketlike on an old log, probably pine. The largest one was about 8.5 cm across. They were fairly tough and flexible. Fertile surface was a reddish brown with thin teethlike structures ~ 2-3 mm long. Spore print was pinkish. Spores were not amyloid. Spores were ~ 7.2-9.0 X 6.0-7.3 microns, broadly ellipsoid and smooth. Q(ave.) = 1.26. Need help with these... Edit 2-22-2013; Most likely the spores are not from the specimens themselves and that they are aged Trichaptum abietinum.
