NotesAscocylindricaceae was introduced by Ariyawansa et al. (2015a) to accommodate the monotypic genus collected from marine habitat based on morphology and phylogeny. Members of Ascocylindricaceae can be easily separated from the other marine taxa in Pleoporales based on their small ascomata, cylindrical asci and bi-celled dark brown to black ascospores.
