Gliomastix was introduced by Guéguen (1905), characterized by darkly pigmented phialoconidia. It is typified by Gliomastix murorum which was previously named as G. chartarum (Hughes 1958; Gams 1971). The placement of Gliomastix is controversial and debated by many authors (Gams 1971; Matsushima 1975; Domsch et al. 2007; Lechat et al. 2010; Kiyuna et al. 2011; Summerbell et al. 2011). Gams (1971) placed Gliomastix in a section of Acremonium. Matsushima (1975) placed Acremonium masseei and A. polychromum in Gliomastix and Lechat et al. (2010) linked G. fusigera  with the sexual morph of Hydropisphaera bambusicola. Kiyuna et al. (2011) and Summerbell et al. (2011) revised and compiled the taxonomy of Gliomastix. Kiyuna et al. (2011) agreed with Gams’s concept and accepted Gliomastix as a section of Acremonium. Furthermore, A. felinum was synonymized under Gliomastix felina and a new species A. tumulicola also was introduced. However, Summerbell et al. (2011) did not follow the Gams’s concept and recognized Gliomastix as a distinct genus. Their phylogenetic analysis supported Gliomastix differs from previous morphological concepts by excluding several distantly related species e.g., Acremonium cerealis and A. inflatum. Maharachchikumbura et al. (2015) and Hyde et al. (2020) followed the treatment of Summerbell et al. (2011) treated Gliomastix as a distinct genus in Bionectriaceae. Our phylogenetic analysis also showed that Gliomastix formed a monophyletic clade within Bionectriaceae (Bao DF et al. 2023), which agrees with Summerbell et al. (2011).

In this study, we collected a Gliomastix taxon which is identified as G. masseei based on both phylogenetic analysis and morphological characters. The new isolate was first time reported from freshwater habitats as well as from China.
