This study aimed to survey lycophyte and fern species in 4 forest fragments in western Paraná, Brazil, and it compares them to other plant formations from the Atlantic Forest biome in southern Brazil. In fragments in western Paraná, 5 lycophyte species were registered, distributed into 2 families and 2 genera. In addition to 100 fern taxa (98 species and 2 varieties), distributed into 16 families and 37 genera. The most representative families were Pteridaceae (23 spp.), Polypodiaceae (18 spp.), Aspleniaceae (13 spp.), and Thelypteridaceae (11 spp.). Among the most representative genera there are Asplenium (12 spp.), Thelypteris (10 spp.), and Blechnum (7 spp.). The occurrence of Dicksonia sellowiana stands out, it is threatened with extinction in Brazil, and this species associated with Semideciduous Seasonal forest. The similarity between areas was identified by means of cluster analysis (UPGMA and Sørensen s Index) and the relation between similarity and geographic distance was determined through Matel s analysis. The analyses revealed proximity of areas in this study to each other, but it is closer regarding fragments in Rio Grande do Sul, Brazil, providing evidence that these areas have similar environmental conditions.
