Dryopteris

 

a genus of ferns of the family Aspidiaceae. There are about 150 species, distributed in the temperate zone of Eurasia and North America and, to a lesser extent, in the tropical regions of Asia, Africa, and South America. The USSR has about 15 species. Especially widely distributed is the male fern (D. filix-mas). D. carthusiana (formerly D. spinulosa) is found in damp, mossy forests of the European USSR, the Caucasus, and Siberia. Both species are used medicinally as anthelmintics. D. fragrans grows on cliffs and slopes of the northern European USSR, in Siberia, and in the Far East; D. cristata grows in humid regions and swamps in the European USSR and Western Siberia.

Male fern is the common fern and there are a number of varieties of Dryopteris available such as copper shield fern, which is also known as the Japanese red shield fern and I have even seen it sold as the painted fern.
The soft shield fern has overlapping leaflets which give it a moss-like appearance, and then there's the prickly shield fern or Polystichum aculeatum, which has spiny projections on its leafy midrib.
