A checklist for identifying Meliolales species

Meliolales is the largest order of epifoliar fungi, characterized by branched, dark brown, superficial mycelium with two-celled hyphopodia; superficial, globose to subglobose, dark brown perithecia, and septate, dark brown ascospores. The assumption of host-specificity means this group a highly diverse and it is imperative to identify the host before attempting to identify a fungal collection. This paper has compiled information from fungal and plant databases, including all fungal species of Meliolales and their host information from protologues. Current names of plants and corresponding fungi with integration of their synonyms are made into an alphabetical checklist, and references are provided. Exclusions and spelling conflicts of fungal species are also listed. Statistics show that the order comprises 2403 species (including 106 uncertain species), infecting among 194 host families, with an additional 20 excluded records. This checklist will be useful for the future identifications and classifications of Meliolales.
