Note. A mycetophagous species associated with the genus Auricularia Bull. ex Juss. , recorded throughout all adjacent regions ( Everts 1903; Libbrecht 1988; Köhler & Klausnitzer 1998; Soldati 2007; Thomaes et al. 2025). However, it appears to be very rare in the Netherlands ( Everts 1903), in decline in Belgium ( Troukens 2005), rare and endangered in Saarland ( Lillig 1999), while seemingly expanding northward in Rhineland ( Lillig 1999). Formerly regarded as very rare in Lorraine ( Géhin 1846; Fournel & Géhin 1847; Godron 1863), it is now considered localized but not very rare (F. Soldati in litt.). In Luxembourg, the species is localized but locally abundant.
