摘要：
Two new species of Dentipellis are described from China based on morphological characteristics and molecular data. Dentipellis longiuscula is characterized by annual, resupinate hydnoid basidiomata with moderately long spines, rough basidiospores (5-6 x 3-3.6 mu m) and absence of gloeoplerous hyphae and gloeocystidia. Dentipellis tropicalis is characterized by hydnoid basidiomata with numerous gloeocystidia presenting in hymenium, and minutely rough basidiospores (5-5.5 x 2.5-3.2 mu m). Phylogenetic analysis based on the internal transcribed spacer (ITS) and nuclear large subunit ribosomal (nLSU) RNA gene regions confirmed the affinity of the new species in Dentipellis and indicated their relationships with other species in the genus.
