“…Microdochium species are commonly known as plant pathogens and saprophytes isolated from diseased plant hosts such as grasses and cereals [ 103 ]. The genus is characterized by its spherical and erumpent stromata and solitary transparent spindle-shaped to oval conidia [ 104 ]. Furthermore, Gyoerffyella species are known as aquatic and terrestrial saprobes and pathogens normally found in decaying leaves [ 105–107 ].…”

A rapid decline of Abies koreana has been reported in most of the natural alpine habitats in Korea. It is generally accepted that this phenomenon is due to climate change even though no clear conclusions have been drawn. Most research has focused on abiotic environmental factors, but studies on the relationships between A. koreana and soil fungal microbiomes are scarce. In this study, the rhizoplane and rhizosphere fungal communities in the alive and dead Korean fir trees from its three major natural habitats including Mt. Deogyu, Mt. Halla, and Mt. Jiri in Korea were investigated to identify specific soil fungal groups closely associated with A. koreana . Soil fungal diversity in each study site was significantly different from another based on the beta diversity calculations. Heat tree analysis at the genus level showed that Clavulina , Beauveria , and Tomentella were most abundant in the healthy trees probably by forming ectomycorrhizae with Korean fir growth and controlling pests and diseases. However, Calocera , Dacrymyces , Gyoerffyella , Hydnotrya , Microdochium , Hyaloscypha , Mycosymbioces , and Podospora were abundant in the dead trees. Our findings suggested that Clavulina , Beauveria , and Tomentella are the major players that could be considered in future reforestation programs to establish ectomycorrhizal networks and promote growth. These genera may have played a significant role in the survival and growth of A. koreana in its natural habitats. In particular, the genus Gyoerffyella may account for the death of the seedlings. Our work presented exploratory research on the specific fungal taxa associated with the status of A. koreana .

“…Twenty-eight new sequences were generated in this study, and available reference sequences of Microdochium species were retrieved from GenBank [ 2 , 3 , 4 , 5 , 6 , 7 ]. Four genetic markers (ITS, LSU, TUB2 and RPB2) were separately aligned using MAFFT v.7.110 (Osaka, Japan) [ 37 ].…”

“…This genus is characterized by spherical and erumpent stromata composed of minute and transparent cells, small papilla, conical sporulation cells and solitary transparent spindle-shaped-to-oval conidia. In recent years, many taxonomists have continuously enriched the known diversity in Microdochium [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Currently, 54 names are listed for this genus in the Index Fungorum [ 9 ], but only 37 species are accepted in the Catalogue of Life [ 10 ].…”

Species in Microdochium, potential agents of biocontrol, have often been reported as plant pathogens, occasionally as endophytes and fungicolous fungi. Combining multiple molecular markers (ITS rDNA, LSU rDNA, TUB2 and RPB2) with morphological characteristics, this study proposes three new species in the genus Microdochium represented by seven strains from the plant hosts Miscanthus sinensis and Phragmites australis in Hainan Island, China. These three species, Microdochium miscanthi sp. Nov., M. sinense sp. Nov. and M. hainanense sp. Nov., are described with MycoBank number, etymology, typification, morphological features and illustrations, as well as placement on molecular phylogenetic trees. Their affinity with morphologically allied and molecularly closely related species are also analyzed. For facilitating identification, an updated key to the species of Microdochium is provided herein.

“…In recent years, the interest in golf has led to an increase in grass areas requiring intensive maintenance. The Microdochium genus includes many species that are highly pathogenic, weakly pathogenic, endophytes, and saprophytes on cereals and grasses ( Kirk & Deacon, 1987 ; Hernández-Restrepo, Groenewald & Crous, 2016 ; Demirci & Dane, 2003 ; Hong et al, 2008 ; Lenc et al, 2014 ; Li, Li & Qi, 2019 ; Gagkaeva et al, 2020 ; Huang et al, 2020 ).

Turfgrass is frequently used today in the arrangement and aesthetic beautification of grounds in parks, gardens, median strips, recreation and sports areas. In this study, surveys were conduct in turfgrass areas in the three provinces of Türkiye. As a result of isolations from the collected samples, 44 Microdochium isolates obtained belonging to five different species including M. bolleyi, M. majus, M. nivale, M. paspali and M. sorghi which have different virulences. Identification of the isolates were performed by rDNA-ITS sequence analyzes. According to the pathogenicity tests results, the most virulent species was M. nivale M62 with a disease severity value of 91.93%. This was followed by M. bolleyi M1584 and M. majus M63, with disease severity values of 91.12% and 91.08%, respectively. The virulence of M. bolleyi isolates varied among the species. Only 13 of the 31 M. bolleyi species were found to be virulent in turfgrass, M. paspali was less virulent than the others in Poa pratensis. The most virulent isolate of each Microdochium species was tested on four different cereal varieties. M. sorghi and M. paspali had low virulence values in barley and oat than the other Microdochium species, while the other three species showed high virulence in turfgrass, wheat and barley, other than oat. In the phylogenetic neighboor-joining tree belonging to 44 Microdochium isolates clearly demonstrated that the isolates were grouped into five distinct clusters. M. nivale and M. majus were considered genetically close isolates.
