Unveiling species diversity within early-diverging fungi from China II: Three new species of (Cunninghamellaceae, Mucoromycota) from Hainan Province.

is distributed worldwide and primarily isolated from soil, feces, and decaying plants. The genus was initially classified into Absidiaceae and then Mucoraceae, and currently belongs to Cunninghamellaceae and is further divided into s.s., , and . Three new species of s.s. are identified and described from soil in Hainan Province of China based on morphological characteristics, molecular data, and maximum growth temperatures as well. They are named based on distinct shapes of projections on columellae: (crystal-like), (pacifier-like), (bowling-like). In SSU-ITS-LSU-TEF- phylogram, the is closely related to and , the is a sister group with , and the has a close relationship with . This study enriches the species diversity of in China.
