Bussabanomyces was named after its collection (Bussaban) from Chiang Mai, Thailand (Klaubauf et al. 2014). This genus belongs to the family Magnoporthaceae and resembles Pyricularia; however, it is different because its conidiophores are usually unbranched, macronematous, and have special cylindrical and denticulate conidiogenous cells that form pale brown conidia with 4–5 septations (Bussaban et al. 2003, Klaubauf et al. 2014). Bussabanomyces longisporus is the only known species in this genus. Formerly named Pyricularia longispora, this genus is an endophyte that was discovered in the leaves of Amomum siamense (Bussaban et al. 2003). The families Magnaporthaceae and Pyriculariaceae are not only phylogenetically different from each other but are also morphologically distinct. The difference in morphology could be inferred from asexual structures, such as falcate versicolor or phialophora-like erected conidiophores (Klaubauf et al. 2014).
Type species: Bussabanomyces longisporus (Bussaban) Klaubauf, M.-H. Lebrun & Crous
