Bjerkandera is overlapping

Bjerkandera is always in overlapping clusters. These are single, although there may be several on one stick. this is definitely not Bjerkandera.

There were several of these on the same stick; in one of the photos, a corner of one can be seen with another centered. If Trametes hirsuta is normally solitary, this is more likely to be Bjerkandera adusta.

On the other hand, there are some small hairs visible in some of the photos. That points the other way, towards an identification of T. hirsuta.
