Clavulicium is a genus of corticioid fungi in the family Stereopsidaceae.

It was formerly placed in the family Clavulinaceae in the order Cantharellales but was found to belong in a new order along with Stereopsis in 2014.

[2][3] The widespread genus was circumscribed by the French mycologist Jacques Boidin in 1957.

[4] The spores and the basidia of species in the genus are similar to those in Clavulina but also similar to those in Stereopsis.

[3] Clavulicium globosum is now a species of Stereopsis.
