A revised genus-level classification for Cerrenaceae (Polyporales, Agaricomycetes).

Abstract

• is a small family of polypores and hydnoid fungi in the order ( ). The family consists of white-rot fungi, some of which are serious tree pathogens. Combining morphological evidence with a phylogenetic dataset of six genetic markers, we revise generic concepts in the family and propose a seven-genus classification system for the family. Two genera are introduced as new: the monotypic for , and for the complex. We re-introduce the name for the complex. Other recognized genera in the family are , and . New species introduced are from Tanzania , and from Southeast Asia, and from East Asia. We provide nomenclatural comments on all the names combined to the above genera and typify , , (= ), , and . The genus belongs to ( ), and we transfer the type species to . Our study highlights the importance of integrating different basidiocarp types in analyses when revising genus classification in macrofungi.
