Abstract
Clavariadelphus species (Clavariadelphaceae, Gomphales) in China were examined using morphology, molecular phylogenetic analyses of ITS data and chemical reactions. Eleven taxa were identified in China, including four species known previously to occur in China (C. griseoclavus, C. ligula, C. sachalinensis and C. yunnanensis), two new record species from China (C. elongatus and C. himalayensis), four novel species (C. alpinus, C. amplus, C. gansuensis and C. khinganensis) and one species that could not be described due to the paucity of material. Finally, we also provided a taxonomic key for the identification of Clavariadelphus species in China.
