Habitat
At least some occur in humid forest where dead, rotting trees or stumps are present. For R. mixtus specifically, the vast majority of known sites are located in naturally important areas with mature forest characteristics.
Distribution
Europe. Documented from Denmark, Norway, and Sweden; additional records from Poland and other European countries. R. mixtus specifically is known from few European countries and was historically considered rare with restricted distribution.
Ecological Role
R. mixtus has been suggested as a potential for evaluating forest naturalness, based on its association with undisturbed, mature forest containing decaying wood.
