Murilentithecium was established by Wanasinghe et al. (2014) using the type species Murilentithecium clematidis, based on morphology and phylogeny (LSU, SSU, TEF1, and RPB2). Later, two more species were accepted in this genus (M. lonicerae and M. rosae), and members of this genus were found in dead plant materials in China and Italy (Wanasinghe et al. 2018, Phookamsak et al. 2019). The sexual morph of Murilentithecium is characterized by coriaceous, dark brown to black ascomata, with a thick peridium and short neck; pseudoparaphyses numerous, filamentous, septate; ascospores have longitudinal and transverse septa, hyaline, muriform, yellowish-brown to brown (Wanasinghe et al. 2014). The asexual morph of Murilentithecium is described as pycnidial, solitary, dark brown, immersed, unilocular conidiomata, with a papillate ostiole; blastic, phialidic, hyaline conidiogenous cells bearing oblong, muriform conidia, constricted at the septa (Wanasinghe et al. 2018, Phookamsak et al. 2019).
