NotesWesterdykella was described as coprophilous producing cleistothecioid ascomata, small asci with short pedicel, encasing one-celled ascospores, verruculose but without germ slits (Kruys & Wedin 2009). Members of Westerdykella have been found in various environmental conditions such as dung, mud, plant material and soil (Clum 1955, Ito & Nakagiri 1995, Cain 1961, Malloch & Cain 1972). Asexual morph produced in culture has conidiomata with sub-cylindrical, aseptate and hyaline conidia (Sue et al. 2014, Crous et al. 2017a).
