R. appendiculatus R. austrororidus R. irritans R. lamprosporus R. mauritianus R. palmensis R. phyllostachydis R. praeclarus R. roridus R. subglobosus Roridomyces is a genus of fungi in the family Mycenaceae.

The genus, widely distributed in temperate areas,[1] was circumscribed by Karl-Heinz Rexer in his 1994 doctoral thesis.

Species in the genus were formerly placed in Mycena section Roridae.

They are characterized by having a slimy, glutinous stipe in moist conditions.

[2] In 2020, a new bioluminescent species, R. phyllostachydis, was discovered in India.
