Abstract
Two Laetiporusspecies, L. ailaoshanensisand L. zonatusspp. nov., are described from southwestern China based on morphological and molecular characters. Laetiporus ailaoshanensisis characterized by orange-yellow to reddish orange pileal surface and cream to buff pores when fresh, azonate to faintly zonate pileus, ovoid to ellipsoid basidiospores (5.0–6.2 × 4.0–5.0 μm), and it has been observed only on Lithocarpus. Laetiporus zonatusis characterized by white to cream pileal surface with buff to clay-buff base when fresh, concentrically zonate basidiocarps, ellipsoid to pyriform or drop-shaped basidiospores (5.8–7.2 × 4.3–5.5 μm), and it has been found only on Quercus. The phylogenetic relationships of all recognized Laetiporusspecies were inferred from a combined dataset of ITS and nLSU-rDNA sequences, and L. ailaoshanensisand L. zonatusrepresent two new lineages in this group.
