Abstract

Global research on saprophytic fungi associated with Tetradium ruticarpum remains limited. In a survey of fungal diversity on T. ruticarpum in southeastern China, six Rhytidhysteron specimens were collected from Anhui, Hunan, and Jiangxi provinces. Phylogenetic analyses, employing Maximum-likelihood and Bayesian inference, were conducted on a combined dataset of LSU, ITS, SSU, and tef1-α sequences. Both morphological and phylogenetic evidence confirmed two new host records of Rhytidhysteron on Tetradium ruticarpum: Rhytidhysteron subrufulum and R. hongheense. Additionally, three isolates previously identified as R. rufulum were reclassified as R. subrufulum based on phylogenetic analyses and morphological characteristics.
