Abstract

A new polypore, Daedalea americana, collected from North and Central America, is described and illustrated based on morphological characters and molecular evidence. It is characterized by annual and pileate basidiocarps, grayish brown with brown to cinnamon brown band and concentrically zonate pileal surface when fresh, cream to clay-pink pore surface, circular to angular pores (4–5 per mm) and ellipsoid basidiospores measured as 4.0–5.1 × 2.1–3.0 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions support D. americana as a distinctive species belonging to Daedalea.
