ABSTRACT
Most known brown rot–producing species of Polyporales belong to the so-called “Antrodia clade” that largely consists of poroid species. In this study, we use three genetic markers to revise Antrodia s. str., the core group of this clade. We show that a corticioid species with a smooth hymenophore, Phlebia griseoflavescens, belongs to Antrodia s. str. Accordingly, we revise the generic concept of Antrodia s. str. to accommodate this species and two recently described poroid taxa, A. tenerifensis and A. multiformis. In addition, we describe two new poroid species within Antrodia s. str., A. latebrosa from Africa and A. peregrina from East Asia, and provide new documentation for the Southeast Asian species A. parvula based on recent collections from the type location.
