First person to use this name on MO: Nathan Wilson
Based on Peter Roberts article (see below), “microscopically, Tremella aurantia can be distinguished from T. mesenterica by its smaller more subglobose spores, smaller basidia, and the presence of unclamped host hyphae in the subhymenium and context. The hymenimum is normally covered by a thick muscous layer full of basidiospores and yeast-like conidia, which presumably is why the surface of the fruit body appears matt and often pruinose.” He also notes that macroscopically in general T. aurantia is more matte and T. mesenterica is more glossy.
This distinction was brought to my attention by Else Vellinga who provided the follow references.
Peter Roberts from Kew Gardens has written several articles on Tremella in Britain:
