Besides host differences, A. auricula-judae has larger spores and is phylogenetically quite distinct. I can not recall any mating studies but as the more closely related A. americana coniferous and deciduous units cannot interbreed (are two different biological species) then one would imagine americana and auricula-judae could not.

from our lab where we worked out some of the Southern species of Auricularia, but we comment on other North American species (including Auricularia americana versus A. auricula-judae).

…because nobody objected the last time I identified something as A. auricula. What is with all of this renaming? Is there any actual evidence (inability to interbreed, presumably) that American wood-ears are not the same species as European wood-ears?

Is not know from the Americas and grows primarily only on Sambucus nigra complex. What we have in Northern North America is A. americana published from Quebec. There are atleast 3 species currently hiding under this name. If yours was on conifer wood it is probably the true A. americana
