Daedaleopsis septentrionalis is one I haven’t seen often, and apparently rare in North America too. If you’re not aware of its existence, it’s easily confused with Lenzites betulina.
The main difference in most descriptions is that the “gills” are pale in Lenzites and some shade of brown i Daedaleopsis. What I have noticed from many pictures, is that the hymenium of a young Daedaleopsis is often bruising brownish, something I have never experienced with Lenzites.
If it’s possible to find spores in this (could be too old), they are clearly longer in Daedaleopsis septentrionalis (7-10 µm and slightly curved).
