Type speciesThielavia basicola Zopf

NotesThielavia was introduced by Zopf (1876) to accommodate a species isolated from the roots of Senecio elegans and lupins. Revisions of the genus have been proposed by numerous investigators (Booth 1961, Malloch & Cain 1973, Mouchacca 1973, von Arx 1975, Figueras & Guarro 1988, Stchigel et al. 2002). Wang et al. (2016a, 2019b) confirmed Thielavia as a monotypic genus in Chaetomiaceae. The genus is characterised by ascomata lacking ostioles and ascospores that are unicellular, darkly pigmented with one or two germ pores. The asexual morph has conidia that are hyaline or brightly coloured and produced as simple phialoconidia, aleurioconidia, or arthroconidia.
