i read this previously and it only contributes more to my confusion.
these were fruiting on a hardwood (oak).
maybe the best option here is, Auricularia.

Literature is sparse

The following excerpt by Andrus Voitk is from the NewFoundland club.
Basically it looks like the conifer associate in North America is A. americana and the deciduous species is undescribed.
The Osprey 17
In Western scientific literature this mushroom was first described from
Europe as Auricularia auricula-judae,because it has the shape of an ear and
was found on an elder tree, the same tree from which Judas hung himself.
The common name in English soon changed from Judas’ ear to Jew’s ear.
Because of the xenophobic potential of these names, the organism has
been renamed Auricularia auricula, the common name Tree ear or Jelly tree
ear. Closer examination revealed that the mushroom in North America
differed significantly from that in Europe,and the American species was
named Auricularia americana. Its European cousin grows primarily
on elder and other deciduous trees,while A. americana is described as a
rotter of coniferous wood. Similar mushrooms are also found on deciduous
wood, but mating experiments showed that organisms from the two
differing substrates would not mate, or would do so with great difficulty.
This suggests the two are, or are evolving to become, different species.
Unfortunately these results have not been explored further. Current DNA
studies might quite likely confirm them as two different species. It is
also possible that the mushrooms along the east and west coasts of
North America have evolved into separate species, as they moved up
and down the continent with their host substrates during periods of
glaciation. Thus, there is plenty of genaeology to be mined here, including the genetic distinction of our species from the European ones
and from those in the Far East, where a larger version,
Auricularia polytricha, is cultivated for eating.

is there…
