Trichoderma (T.), was established by Persoon in 1794, with T. viride designated as the type species. Currently, approximately 500 Trichoderma species are recorded in Species Fungorum (2024). Members of Trichoderma are distributed worldwide and are found on various hosts and substrates, such as Abies alba, Dactylis glomerata, Lycopersicon esculentum, Medicago sativa, and Phaseolus vulgaris from Poland (Mulenko et al. 2008), Eucalyptus sp. from South Africa (Bissett et al. 2015), Fomes pinicola from the USA (Bissett et al. 2015), Ipomoea batatas from China (Yang et al. 2021), Lycopersicon esculentum from Brazil (Mendes et al. 1998), Prunus padus from Austria (Urbez-Torres et al. 2020), Solanum lycopersicum from Canada (Johnston-Monje et al. 2017), and Vitis vinifera from Italy (Lorenzini et al. 2016). In this study, we report T. virens as a new record on dead leaves of Eleiodoxa conferta from the peat swamp forest in Narathiwat, Thailand.

Type species: Trichoderma viride Pers., Neues Mag. Bot. 1: 92 (1794)

Other accepted species: Species Fungorum – search Trichoderma.
