The karst regions of southwest China are rich in biodiversity and have critically threatened ecosystems, harboring unique species that could be new to science. During the investigations of arthropods associated-fungi, several fungal strains were collected. Among these, three new species, Conoideocrella tiankengensis sp. nov. (Clavicipitaceae), Ovicillium zunyiense sp. nov. (Bionectriaceae) and Trichothecium sinense sp. nov. (Myrotheciomycetaceae), isolated from a dead scale insect, larva and spider, respectively, were introduced as novel taxa, based on the morphological characteristics and DNA-based phylogenetic analyses. This is the first time that a species from Myrotheciomycetaceae is reported from the karst habitats. In addition, the genus Myrotheciomyces is treated as a synonym of Trichothecium based on the phylogenetic analysis, and the type species of the former is transferred to the latter genus.
Chen et al. (Fri,) studied this question.
