Chen, Wan-Hao, Shu, Hui-Lin, Li, Dan, Liang, Jian-Dong, Ren, Xiu-Xiu, Wijayawardene, Nalin N., Han, Yan-Feng & Zhao, Jie-Hong, 2025, Morphological and phylogenetic evidence reveals three new arthropod-associated species of Hypocreales (Clavicipitaceae, Bionectriaceae, and Myrotheciomycetaceae) from karst habitats in Guizhou, China, MycoKeys 123, pp. 319-353 : 319-353

Trichothecium corymbiae (Crous) W. H. Chen & Wijayaw. comb. nov.

= Myrotheciomyces scorymbiae Crous , Persoonia 40: 351, 2018.

Note.

We proposed to treat Myrotheciomyces as a synonym of Trichothecium based on the phylogenetic analyses (Figs 1 , 4 ) and therefore transferred Myrotheciomyces corymbiae to the genus Trichothecium as Trichothecium corymbiae .

Figures

Figure 1. Phylogram retrieved from IQ-TREE to confirm the familial placements of the new strains using the combined dataset of ITS, LSU, RPB 2 and tef - 1 α gene regions. The statistical values are provided at nodes as ML / PP (ML value above 70 % and BI value above 0.70). The tree is rooted with Gelasinospora tetrasperma (AFTOL-ID 1287), Neurospora crassa (ICMP 6360) and Sordaria fimicola (AFTOL-ID 216). Ex-types and new strains are indicated by the superscript “ T ” and in bold, respectively.

Figure 4. Phylogram retrieved from IQ-TREE of the placement of new strains in Trichothecium s. str. using the combined dataset of ITS, LSU, RPB 2 and tef - 1 α gene regions. The statistical values are provided at nodes as ML / PP (ML value above 70 % and BI value above 0.70). The tree is rooted with Clonostachys phyllophila (CBS 921.97) and Clonostachys spinulosispora (CBS 133762). Ex-types, new strains are indicated by the superscript “ T ” and in bold, respectively.
