Mycena cyanorhiza has been studied critically by both Kuhner and Josserand. Its pileus is 3-9 mm. broad across the base the stipe is 1-3 cm long and 0.2-1 mm thick. The pileus has the typical gelatinous pellicle. The stipe is entirely pubescent and looks as if it had been powdered with blue near the base. The gills are described as being fairly close and as having gelatinous edges, an unusual and distinctive character for a species of this group.
