Efibula
Efibula Sheng H. Wu 1990, in Gorjón, Studies in Fungi 5(1), 199 (2020).
Diagnosis: Basidiome effused, subceraceous or ceraceous, hymenial surface usually smooth. Hyphal system monomitic, hyphae simple-septate. Subiculum composed of a thin basal layer, and a prominent medullary layer with dense or compact texture. Cystidia usually lacking. Basidia clavate, 4-sterigmate. Basidiospores ellipsoid or narrowly ellipsoid, smooth, thin-walled, IKI–, CB–.
Index Fungorum Number: IF25473
Type Species: Efibula tropica Sheng H. Wu 1990
Notes. Efibula has usually been included in Phlebia because of its dense contextual texture, or in Phanerochaete because of its simple-septate hyphae; but its relationship to the core of the two other genera seem to be distant. Efibula can be separated from Phlebia s.str. mainly by its simple-septate hyphae, but the separation from Phanerochaete requires more careful study. The medullary layer of Efibula is rather compact, all hyphae being interwoven and without a tendency to horizontal orientation. In Phanerochaete the subiculum usually has a somewhat loose texture, always having distinct spaces between the hyphae, which are usually straighter and horizontally oriented. Efibula was originally described to include two new species from Taiwan and some species formerly placed in Phlebia and Phanerochaete, characterized by simple-septate generative hyphae and dense contextual texture. Zmitrovich et al. (2006) expanded Efibula by transferring many acystidiate Phanerochaete species under this generic name. As it has been shown later (Wu et al. 2010) Efibula as seen by Zmitrovich et al. (2006) is polyphyletic.
