Type species – Lunatiannulus irregularis Daranagama, Camporesi & K.D. Hyde
Notes – This diatrypaceous-like genus was introduced to accommodate species with ascomata with a well-developed clypeus, cylindrical asci with an apical ring, ellipsoidal ascospores with germ slits and hyaline appendages or dwarf cells and a libertella-like asexual morph. Daranagama et al. (2018) accepted this genus in Xylariaceae based on morphology and multigene phylogeny.
