Abstract
A terrestrial wood-inhabiting pyrenomycete was collected numerous times in the Neotropics. It possesses superficial, clustered ascomata, large, distinctive ascus rings and strongly guttulate, fusiform ascospores. A second similar pyrenomycete was collected once in Costa Rica. They could not be placed into any known genus, so a new genus, Mirannulata, is described. Mirannulata samuelsii has hyaline, fusiform, three-septate ascospores while M. costaricensis has brown, fusiform, one-septate ascospores. Mirannulata has a very large, chitinoid, double-layered ascus apical ring similar to that of Annulatascus and Jobellisia.
