Dichotomopilus established by Wang is based on the type species, D. indicus. The fruiting bodies of this genus have unique characters; they consist of dichotomically branched terminal hairs and are saprobic in nature. Many Chaetomium species were transferred and two new species, D. pseudofunicla and D. pseudoerectus were introduced to this genus (Wang et al. 2016). Dichotomopilus species are widely distributed in Asia, Europe, North America and moderately in Australia (New Guinea) (Zhang et al. 2017, Hyde et al. 2020a). Most of them were found in interiors, outdoors and on decomposing twigs (Wang et al. 2016, Hyde et al. 2020a), Phukhamsakda et al. 2020). Twelve species were known so far (Index Fungorum 2020). In phylogenetic analysis (Fig. 67), Dichotomopilus nested with Chaetomium, revealing both a morphological and molecular resemblance.
