Abstract The new species Byssoloma catillariosporum and Porina isidioambigua are described from NE Brazil. The first is reminiscent of B. leucoblepharum but differs by the consistently uniseptate ascospores. The second is characterized by tiny isidia and black perithecia with relatively large, 3-septate ascospores. Both species were found at the Área de Proteço Ambiental (APA) Morro do Urubu, an area of c . 214 hectares in the large (500 000 inhabitants) city of Aracaju. It is the only urban Mata Atlântica remnant in Aracaju, with mesophytic deciduous and semi-deciduous forest, and cerrado enclaves in isolated points.
