      Maximum likelihood phylogram inferred from 82 taxa and 1401 characters based on ITS, and LSU matrix using GTR+G+I model. ML bootstrap supports (≥ 70%) and Bayesian posterior probability (≥ 0.70) are indicated above the branches or near the nodes as ML/ML/PP. Tree is rooted using Cunninghamella homothallica (CBS 168.53), C. phaeospora (CBS 692.68), and C. bainieri (FSU319). Strains of the new species are in bold and the type species in the dataset are indicated using T. (−) represent bootstrap support lower than 70%.
