The soil is one of the most important habitats for microorganisms, among them the fungi. Xingó is a region characterized by typical caatinga ecosystems. The aim of this research was to isolate and identify filamentous fungi from soils of the Xingó region using samples collected at the soil surface and at 20 cm depth, in the districts of Canindé de São Francisco (Sergipe), Olho D'água do Casado (Alagoas), and Piranhas (Alagoas), during the rainy (May and July/2000) and dry seasons (March/2001). We identified 96 taxa belonging to eight species of Ascomycota, eight species of Zygomycota and 80 anamorphs, with one species of Coelomycete and 79 species of Hyphomycetes. Penicillium and Aspergillus were the most diverse genera with 31 and 17 species, respectively.
