Abstract

The genus Cunninghamella is widely distributed, primarily saprotrophic, occasionally endophytic and phytopathogenic. Analysis based on the internal transcribed spacer (ITS), the large subunit (LSU) of ribosomal DNA, and translation elongation factor 1 alpha (TEF1α), along with morphological comparisons, resulted in a discovery of eight new species. Molecular phylogenetic analyses placed each of these new species within well-supported clades. Cunninghamella crassior sp. nov., with short and thick spines, and C. fusca sp. nov. with brown sporangiola, are sister clades to each other. C. diffundens sp. nov., containing dispersed granules in sporangiola, is closely related to C. irregularis Zhao. C. tuberculata sp. nov., producing sporangiola with nodule-like protrusions. C. fulvicolor sp. nov., sister to C. irregularis, forms yellowish-brown pigmented colonies. C. guttulata sp. nov., with teardrop-shaped sporangiola, and C. inaequalis sp. nov., with uneven sporangiola, are both closely related to C. regularis Zhao. C. monosporangiola sp. nov., characterized by only one sporangiolum on some vesicles, is sister to C. verrucosa Zhao. This study represents the eleventh installment in a series investigating early-diverging fungal diversity in China and expands the number of accepted species in Cunninghamella to 39.
