Chlorocillium sinense sp. nov. (Clavicipitaceae) and Calcarisporium guizhouense sp. nov. (Calcarisporiaceae) in Hypocreales from China

Two new species, <i>Chlorocilliumsinense</i> and <i>Calcarisporiumguizhouense</i>, isolated from a spider and fruiting body of <i>Cordyceps</i> sp., are introduced. Morphological comparisons and phylogenetic analyses based on multigene datasets (ITS+LSU+<i>RPB2</i>+<i>tef</i>-1alpha) support the establishment of the new species. A combined dataset of ITS, LSU, <i>RPB2</i>, and <i>tef</i>-1alpha showed the taxonomic placement of <i>Chlorocillium</i> in Clavicipitaceae for the first time. <i>Pseudometarhizium</i> is regarded as a synonym of <i>Chlorocillium</i> and two <i>Pseudometarhizium</i> species are transferred into the latter based on the phylogenetic analysis and morphological characteristics.
