Notes – Munk (1953) introduced Herpotrichiellaceae to accommodate Herpotrichiella based on the type species H. moravica. The family Herpotrichiellaceae has the largest number of species in Chaetothyriales (Wijayawardene et al. 2017, Quan et al. 2020). Species of Herpotrichiellaceae are characterized by superficial, setose, ostiolate, small ascomata with short and extending periphyses near or over the ostiole, bitunicate asci with a thickened endotunica and greenish-grey to brown, 1-multi transversely septate ascospores, rarely with longitudinal septa (von Arx & Müller 1975, Barr 1976, 1991, Samuels & Müller 1978, Müller et al. 1987, Untereiner et al. 1995). The asexual morphs of Herpotrichiellaceae are dematiaceous, black yeasts (Müller et al. 1987, Untereiner et al. 1995, Untereiner & Naveau 1999, Crous et al. 2007, Untereiner et al. 2008, de Hoog et al. 2011, Réblová et al. 2013, Gueidan et al. 2014, Liu et al. 2015, Dong et al. 2018, Untereiner 2020). It is difficult to distinguish species, especially the dematiaceous asexual morphs, based on limited features, and therefore molecular sequences are essential for species delimitation. 

Before molecular data, the systematics of Herpotrichiellaceae was confused. Munk (1953) recognized that species in Herpotrichiellaceae should be similar to species in Coenosphaeria and Trichometasphaeria in Dothideomycetes. Müller & von Arx (1962) and Bigelow & Barr (1963) rejected the classification of Herpotrichiellaceae and placed the type genus Herpotrichiella in Pleosporales, Dothideomycetes. Herpotrichiellaceae was considered to be related to Capnodiales and Dothideales in Dothideomycetes, until Barr (1976, 1987) and Sivanesan (1984) regarded Herpotrichiellaceae is closely related to Chaetothyriales. In this study, 18 recognized genera are accepted in this family. 

Petrak (1914) introduced Herpotrichiella with H. moravica as the type species. Untereiner et al. (1995) compared two collections CBS 125.88 and CBS 522.79 (identified as
H. moravica), and found that they are morphologically indistinguishable. Subsequently,
H. moravica was considered as a synonym of Capronia pilosella (Untereiner 1997). Thus, Quan et al. (2020) synonymized Herpotrichiella under the older name Capronia with the type species Capronia sexdecimspora. In their study, because of the lack of molecular data of Capronia sexdecimspora, they considered C. pilosella (AFTOL 657) as a reference for the family. We follow Quan et al. (2020) to synonymize Herpotrichiella under the older name Capronia.
