Efibula

Efibula is a genus of 16 species of crust fungi in the family Irpicaceae.

Taxonomy
The genus was circumscribed by Sheng-Hua Wu in 1990 with Efibula tropica as the type species. Efibula contains Phlebia-like fungi without clamp connections. Although traditionally classified in the family Phanerochaetaceae, recent molecular phylogenetic analysis supports the placement of Efibula  in the Irpicaceae.
