Abstract
Two new species of poroid Hymenochaetaceae (Aphyllophorales, Basidiomycota) are described and illustrated. They were causing decay on living and standing dead Polylepis australis (“tabaquillo” or “queñoa”) in the Córdoba Mountains in central Argentina. Inonotus serranus is characterized by a biannual basidiocarp, with a dark line separating tomentum from context; ellipsoid to ovoid, thick walled, colored spores; and the absence of setae. Phellinus uncisetus is characterized by uncinate setae with ventricose uniradicate base and well-differentiated apical portion; a basidiocarp attached by a narrow area to the substrate; ventricose, hyaline cistidioles; and by subglobose, hyaline spores, with very thick walls. The identity of Phellinus setulosus is discussed.
