Seven families present monolete spores (Aspleniaceae, Blechnaceae, Dryopteridaceae, Gleicheniaceae, Lomariopsidaceae, Polypodiaceae y Thelypteridaceae), eight present trilete spores (Cyatheaceae, Dicksoniaceae, Grammitidaceae, Hymenophyllaceae, Lophosoriaceae, Lycopodiaceae, Plagiogyriaceae y Pteridaceae), one family presents both spore types (Dennstaedtiaceae) and only Equisetaceae presents alete spores. The dominant exinic sculpture patterns are psilate and verrucate. The most frecuent shape is oblate spores. The spores of Aspleniaceae, Blechnaceae, Dennstaedtiaceae, Dryopteridaceae, Equisetaceae, Lomariopsidaceae, Lophosoriaceae, Polypodiaceae, Pteridaceae y Thelypteridaceae present perine, in Lophosoriaceae and Pteridaceae special structures.
