Thanks a lot for the ID! This is enlightening, but confusing too - I didn’t anticipate I would need to go into pycnospores, hypo- and epibasidia when started collecting. Now it seems I need to do some reading.

According to MatchMaker/Key Council, C. cerasi is known in the Pacific NorthWest, and the descriptions given there seems a good match. These jellies were indeed growing on the bark of Populus (cottonwood), on “large dead branches or trunks, fallen, and lodged on shrubs”.

I added some close-ups and crappy microshots. The “banana clusters” (spores) in the third micrograph are from the little (disc-like) guys.

are probably not spores, these are more likely the basidia!
The size and shape of them, as vell as the colour, size and shape of the fruitbodies, fits well with Craterocolla cerasi. Look at the small ones, they remind of ascomycetes..

Thanks for the ID. My microshot is awful, but the spores looked rough to me, and in T. foliacea they should be smooth [Arora, MD]. Will try to look at it later, if I get time.
