Observation 164071: Lenzites betulina (L.) Fr. (Site ID) (Trametes betulina)

Notes:
One fruiting body cluster
Habitat: on Alnus in wet shrubby forest

I considered other similar type spp (Gloeophyllum, Daedalea) but this seems like the best ID. On hardwood, gills fairly thin and long with few cross walls and not mazelike, light and zoned on top, bottom now quite dark but presumably lighter when was fresh.

Later (May 2, 2014)
KOH darkens it a little, but not super dramatically. This was done on the dried specimen (not fresh) if that makes a difference. The KOH solution was 5%.
It looks more similar to the Lenzites betulina reaction than the Daedaleopsis septentrionalis reaction in observation 32700

Daedaleopsis septentrionalis actually looks like a good fit. I was reading a similar observation for more info:

I can easily do a KOH test next week. I’m tempted to try some microscopy too, but will have limited equipment, skill, time, and patience.

This at least explains the dark gills.
