My floating technique always works. and yes the dendrohyphidia are branched.

I know how hard it can be to find spores in the microscope from an old polypore.. Without knowing the size, at least the shape of spores and basidia is a good match. Did you notice any branched dendrohyphidia on the gills?

of the same Daedaleopsis septentrionalis from the NEMF foray that Dianna Smith has on PBase. I will post it when I get home next week…
This one looks like the common southern form (species?)that we saw lots of at the NAMA foray in Louisiana, I think I photographed it… but these pictures are also at home.

I have 6 specimens from this birch log. some are still tissue like texture and not cardboard so ill try and float some spores up. I have a method i came up with (at least I think I did) using a zinc sulfate solution. I’m able to float spores of fungi that are difficult to get a spore print on or obtain spores.

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).

There are some not so fresh but those are bit brittle like cardboard. I put a comparison of the two species up. Thes are both at he same freshnes. I have sen L betulina as a very old fruiting body and I have yet to see the gills type surface turn this dark. This also turns black in KOH where as Lenzites betulinea does not. but turns a slight brown.

Fresh frozen and now thawed seems more likely. What makes you think they just fruited?

For the sake of argument lets call them gills even though they are not. The gills are light in those images and more maze like. The gills on these specimens are brown. In image 74593 is some what of a young specimen. The gills are a purple brown and as the fungi ages they become a dark brown.

But here are some young ones:

more pics, unfortunately not showing the “gills”:

I thought Daedaleopsis has more of a maze like pore surface. The pore surface here is gilled like Lenzites betulina but very dark.
