Classification: Irpicaceae, Polyporales, Incertae sedis, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi

Notes: Efibula was described by Wu (1990) to accommodate species previously included in Phlebia (Ph. deflectens) and Phanerochaete (Ph. avellanea and Ph. pallidovirens, in addition, two new species Efibula lutea and Efibula tropica were also described and proposing E. tropica as the generic type. Two more species were accommodated in the genus by Kotiranka and Saarenoska (1993) i.e., Efibula rosea and E. verruculosa. Zmitrovich et al. (2006) enlarged the genus with eight more species, E. aurata, E. bubalina, E. cordylines, E. corymbata, E. ginnsii, E. subodontoidea, E. subquercina and E. tuberculata. Subsequent phylogenetic analysis (Wu et al. 2010) showed that Efibula sensu Zmitrovich et al. (2006) was polyphyletic and, according to Floudas and Hibbett (2015), only five species were accepted in the genus namely E. americana, E. clarki, E. gracilis, E. tropica and E. tuberculata. From a morphological point of view, the species included in this genus are characterized by their basidiomata resupinate, effused, subceraceous to ceraceous; smooth hymenophore; compact subiculum, with hyphae densely interwoven; monomitic hyphal system, hyphae mostly without clamps; cystidia absent; basidia with four sterigmata; spores ellipsoid to broadly ellipsoid, thin-walled, smooth and hyaline, Melzer (–), and acyanophilous (Wu 1990; Floudas and Hibbett 2015). 

Type species: Efibula tropica Sheng H. Wu, Acta bot. fenn. 142: 25 (1990).

Other accepted species: Species Fungorum – search Efibula.
