A crust-like jelly fungus (Auriculariales) that forms thin, violet-pinkish patches with scattered small spines on dead hardwood branches. It causes a white rot and is most often found on hazel (Corylus) and ash (Fraxinus). It was moved from Eichleriella to Heteroradulum in 2017; Heteroradulum differs from Eichleriella by its encrusted hyphal ends.
Not edible; a thin crust on dead wood with no food use.
