Nitschke (1869) introduced the family Lophiostomataceae with Lophiostoma, as the type genus. Since then, several genera have been introduced into this family (Trevisan 1877, Kohlmeyer & Kohlmeyer 1991, Crous et al. 2013, Thambugala et al. 2015, Hashimoto et al. 2018, Mapook et al. 2020, Maharachchikumbura et al. 2021, Wanasinghe et al. 2021). Currently, there are 32 accepted genera in Lophiostomataceae (Hyde et al. 2024). Members of Lophiostomataceae are reported as saprobes on stems, bark or twigs of various woody and herbaceous plants in both terrestrial and aquatic environments (Mapook et al. 2020). The sexual morph is characterized by having superficial or semi-immersed to densely erumpent, globose to subglobose, dark-brown to black and carbonaceous ascomata, with an elongate, often slit-like ostiole, with a peridium of thin-walled and lightly pigmented cells of textura prismatica, and long, hyaline, septate, anastomosing and branched pseudoparaphyses. Their asci are 8-spored, bitunicate, fissitunicate, cylindrical to clavate, comprising 1-seriate or partially 2-seriate, hyaline to pale brown, narrowly fusiform, 3–5-septate or muriform ascospores that are slightly constricted at each septum and with acute ends. The ascospores are smooth-walled, with a distinct oil drop in each cell, and with terminal appendages (Hongsanan et al. 2020). The asexual morph is reported as coelomycetous, characterized by subglobose, semi-immersed, uni-loculate or rarely bi-loculate, reddish brown pycnidia, with conidiophores reduced to conidiogenous cells. These conidiogenous cells are cylindrical, phialidic, and hyaline, formed at the end and on the sides, producing subglobose to cylindrical, hyaline, aseptate conidia (Hongsanan et al. 2020).
