Ingoldian fungi have a worldwide distribution, but the most species have been described from temperate regions. In Brazil, the studies of Ingoldian fungi started in the 1980’s in the Atlantic Forest, the state of Sao Paulo. Later studies extended to other biomes such as the Cerrado, Caatinga and Amazon. The aim of this study is to improve our understanding of the occurrence and distribution of Ingoldian fungi in Brazil. Here, we include and discuss several new records for Brazil associated with submerged leaves of Calophyllum brasiliense and provide a checklist, a key and illustrations for all species of the Ingoldian fungi recorded from Brazil, as well as distribution maps. Flagellospora stricta is a new record to the Americas; Dendrosporomyces prolifer and Geniculospora inflata to the Neotropics; Pyramidospora casuarinae and Triscelophorus monosporus are new records to the Caatinga. With the new additions of species associated with submerged leaves of C. brasiliense, a total of 85 taxa of Ingoldian fungi are now recorded in Brazil. Nineteen taxa are reported from the Amazon, 53 from the Atlantic Forest, 39 from the Caatinga and 21 from the Cerrado.
