![]() Wu and collaborators (2015) attempted to name this third species " Auricularia angiospermarum." However, the Wu publication did not include the correct Mycobank number in the original description of the species, and the name is therefore officially invalid. Instead, we have several genetically distinct species, including: Auricularia americana in the strict sense, which grows on the wood of conifers and, under the microscope, has no medullary zone Auricularia fuscosuccinea, which grows on the wood of hardwoods in the southeastern United States and has a distinct medullary zone and a species-the one described here-that grows on the wood of hardwoods and has no medullary zone. The names Auricularia auricula and Auricularia auricula-judae have been traditionally applied to the mushrooms described here, but fairly recent research (Looney and collaborators 2013, Wu and collaborators 2015) has determined that the auricula-like North American species of Auricularia are not properly placed under those species names. In the southeastern United States, Auricularia fuscosuccinea is virtually identical, to the naked eye, but differs microscopically (see discussion below). Similar jelly fungi include Exidia recisa, which features ridged, concave depressions, and Tremella foliacea, which is a bit more gelatinous and appears like a tightly packed cluster of jelly ears that are fused together. When young and fresh, its underside appears frosted with a whitish dusting, but this often disappears quickly. Its surfaces are brown to reddish brown, and the consistency of the flesh is rubbery and gelatinous. Appearing on the wood of hardwoods or conifers, especially after rains or in wet conditions, the jelly ear ranges from disc-shaped to ear-shaped to irregular and floppy. One look at this fungus and you can see why people think Auricularia americana looks like the missing part of a Van Gogh self portrait.
