Two New Species and a New Record of <i>Microdochium</i> from Grasses in Yunnan Province, South-West China

<i>Microdochium</i> species are frequently reported as phytopathogens on various plants and also as saprobic and soil-inhabiting organisms. As a pathogen, they mainly affect grasses and cereals, causing severe disease in economically valuable crops, resulting in reduced yield and, thus,...

Description
Summary:<i>Microdochium</i> species are frequently reported as phytopathogens on various plants and also as saprobic and soil-inhabiting organisms. As a pathogen, they mainly affect grasses and cereals, causing severe disease in economically valuable crops, resulting in reduced yield and, thus, economic loss. Numerous asexual <i>Microdochium</i> species have been described and reported as hyphomycetous. However, the sexual morph is not often found. The main purpose of this study was to describe and illustrate two new species and a new record of <i>Microdochium</i> based on morphological characterization and multi-locus phylogenetic analyses. Surveys of both asexual and sexual morph specimens were conducted from March to June 2021 in Yunnan Province, China. Here, we introduce <i>Microdochium graminearum</i> and <i>M. shilinense,</i> from dead herbaceous stems of grasses and report <i>M. bolleyi</i> as an endophyte of <i>Setaria parviflora</i> leaves. This study improves the understanding of <i>Microdochium</i> species on monocotyledonous flowering plants in East Asia. A summary of the morphological characteristics of the genus and detailed references are provided for use in future research.
