Diversity of the genus
Although there are 92 Helicoma epithet in Index fungorum, the real number of species is less as many have been synonymized and transferred to other genera such as Camporesiomyces, Chlamydotubeufia, Cirrenalia, Dematiohelicoma, Dematiotubeufia, Drepanospora, Helicofilia, Helicomyces, Helicosporium, Helicotruncatum, Neohelicoma, Neohelicosporium, Pseudocercospora, Thaxteriella, Trochophora, Tubeufia, Xenosporium, Zalerion. Helicoma comprises 64 species known on several host plants and plant families such as Anacardiaceae, Araliaceae, Arecaceae, Betulaceae, Dilleniaceae, Euphorbiaceae, Fagaceae, Myrtaceae, Pandanaceae, Salicaceae, Sapindaceae amongst others. Helicoma has a worldwide distribution such as Canada, Cuba, Dominican Republic, Florida, Hawaii, Hong Kong, Japan, Mexico, Ohio Russia, South Africa, Western Cape, Taiwan, Tanzania, Venezuela amongst others. Comprehensive studies are likely to discover more species of Helicoma.
