Chaetomium Kunze, Mykologische Hefte 1: 15 (1817)

Index Fungorum number: IF953

Type species: Chaetomium globosum Kunze, Mykologische Hefte 1: 16 (1817).

Notes: The genus Chaetomium was introduced by Kunze (1817). Chaetomium is the largest group in Chaetomiaceae , with more than 350 accepted species. This ascomycetous generic taxa are commonly found in soil, air, or on plant debris ( Udagawa et al. 1997, Zhang et al. 2017). Phylogenetic evidence suggested that Chaetomium is a polyphyletic genus related to several anamorphic genera, with distinctions between Achaetomium , Chaetomium , and Thielavia being ambiguous ( Wang et al. 2019, 2022c). The sexual morph is characterized by having ascomata with pore-like opening and usually covered with a high diversity of hairs or setae (straight; arcuate; undulate; undulate with coiled tips; sinuous to loosely coiled; compactly coiled and dichotomously branched), membranaceous peridium, paraphyses, fusiform or cylindrical, fasciculate, evanescent, 8-spored asci, formed single-celled ascospores, with germ pores; the asexual morph was described with globose, catenate conidia ( Wang et al. 2016 a, Abdel-Azeem 2020). Because of its high diversity and significant potential in biocontrol, Chaetomium has recently become an important research topic ( Yang et al. 2023a).
