Species of Lophiostoma mostly have immersed to erumpent ascomata, cellular pseudoparaphyses, and hyaline to dark brown septate ascospores, often with sheaths or appendages. Based on the formation of a slit-like ostiolar opening on a laterally compressed papilla, Lophiostoma was placed in its own family, Lophiostomataceae (Dothideomycetes).
Species of the genus are common in the tropics, and occur on submerged as well as terrestrial wood, but also occurs on leaf litter.
