Type species – Xenomyrothecium tongaense (W.B. Kendr., DiCosmo & Michaelides) L. Lombard & Crous
Notes – Xenomyrothecium was introduced by Lombard et al. (2016) to accommodate X. tongaense (≡ Myrothecium tongaense). The genus is characterised by sporodochial, stromatic conidiomata, hyaline conidiophores, phialidic, pale green conidiogenous cells and aseptate, oblong- ellipsoidal, pale green conidia (Lombard et al. 2016). The genus differs from other genera by its oblong-ellipsoidal conidia and lack of setae formed in the sporodochia.
