Some on White Pine wood, some on hemlock.
Formerly D. palmatus.

Actually, my internet search yielded only one page from the study. The link in your comment provides the entire write-up, which I’ll save.
I’m posting another micro. Didn’t add any stain, so some details may be hiding. But around the middle of the photo (near end of pointer) there are a few structures that look like thick-walled marginal hyphae of D. chrysospermus. I’m guessing such hyphae are terminal strands.
That I read, its pretty informative, I need to go back and try to scope my desiccated Dacrymyces chrysospermus collection too… Img 400182 is an example of the tuning fork basidia, I was just saying looking at the basidia is always good practice when dealing with jelly fungi. As for the marginal hyphae, look at the illustrations in that study, its f for D. aureosporus & e for D. chyrsospermus. Also, absence of evidence is not evidence in itself.
Here is the paper for those that don’t have it yet.
“Dacrymyces aureosporus resembles D. chrysospermus, but differs in wall thickness of its marginal hyphae.”
I searched with the scope for awhile but didn’t see anything that clearly looked like forked basidia. Online sources state that forked basidia are a character associated with the genus Dacrymyces. So I’m not sure this would be all that useful here.
The one micro shows two segmented spores, one more clearly than the other. One shows 9 segments, the other 8 or 9. This is consistent with the “8 to 10” reported for D. chrysospermus (palmatus).
Does “thick-walled terminal cells on the sterile surface of the basidiocarps" refer to the same character as “wall thickness of its marginal hyphae”? I don’t know how to examine this trait.
I can find no report mentioning the occurrence of D. aureosporus in North America. Thus, at least for the time being, I see no reason for considering anything other than calling this “Dacrymyces chrysospermus.”
As long as you’re going to scope these a image of the tuning fork basidia would be nice, they’re easy to find, also how many septations do the spores have and you should really look for “thick-walled terminal cells on the sterile surface of the basidiocarps” as there is also D. aureosporus to consider…
