Previous molecular phylogenetic analysis in comparison with phenotype characters of Gomphillaceae resolved a total of 38 genus-level clades among the studied species, 17 of which in need to be recognized and formally established as new or reinstated genera. The four reinstated genus names, including one validation, are Microxyphiomyces Bat., Valle & Peres, Psathyromyces Bat. & Peres, Spinomyces Bat. & Peres ex Xavier-Leite, M. Caceres & Lucking, gen. nov., and Sporocybomyces H. Maia. The remaining 13 are newly described: Adelphomyces Xavier-Leite, M. Caceres & Lucking, gen. nov., Aptrootidea Xavier-Leite, M. Caceres & Lucking, gen. nov., Aulaxinella Xavier-Leite, M. Caceres & Lucking, gen. nov., Batistomyces Xavier-Leite, M. Caceres & Lucking, gen. nov., Bezerroplaca Xavier-Leite, M.
