Morphological plasticity in brown-rot fungi: is redefined to encompass both poroid and corticioid species.

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 s. str., the core group of this clade. We show that a corticioid species with a smooth hymenophore, , belongs to s. str. Accordingly, we revise the generic concept of s. str. to accommodate this species and two recently described poroid taxa, and . In addition, we describe two new poroid species within s. str., from Africa and from East Asia, and provide new documentation for the Southeast Asian species based on recent collections from the type location.
