Abstract

Arabica coffee (Coffea arabica), which accounts for approximately 60–70% of global coffee production, is renowned for its superior flavor and aroma. During a survey of microfungi on coffee plants, a new species, Pseudodictyosporium yunnanensis sp. nov., belonging to Dictyosporiaceae, was collected on dead twigs of an Arabica coffee plant in Yunnan Province, China. Phylogenetic analyses of combined ITS, LSU, SSU, and tef1-α gene sequences confirmed that this fungus shows a distinct clade in the genus Pseudodictyosporium. The morphological characteristics of this fungus also support its classification as a novel species. A detailed description, illustrations, and a phylogenetic tree demonstrating the placement of this new species within Pseudodictyosporium, are provided.
