Diversity of the genus
Although there are 49 Dimeriella epithets in Index fungorum, the real number of species is less as many have been synonymized and transferred to other genera such as Acanthostoma, Antennularia, Asterina, Dimerina meyeri-hermanni, Eudimeriolum, Lasiostemma, Perisporiopsis, Phaeocryptopus, Phaeodimeriella, Pyrenophora, Rasutoria, Wentiomyces, Zasmidium. Dimeriella comprises 25 species known on several host plants and plant families such as Celastraceae, Asphodelaceae, Asteraceae, Boraginaceae, Cyatheaceae, Moraceae, Pinaceae, Poaceae or Gramineae, Sapindaceae and Zingiberaceae. Dimeriella has a worldwide distribution, common in Australia, Barbados, Brazil, California, Cambodia, China, Dominican Republic, Ecuador, Ghana, Guinea, India, Japan, Malawi, Panama, Philippines, Southern Africa, Taiwan, Trinidad and Tobago, Venezuela. Dimeriella seems to be a diverse genus but lacks molecular data. Fresh collections are required.
