Dryopteris lacunosa is a species of the Dryopteris affinis aggregate, which has been described not until 2011. The fern grows in damp woods, preferably but not only on sour soil. It differs because it has a wider distance between the first two or three leaflets near the stem than between the motre outside ones. Up to now occurrences in Southwest Germany, Switzerland, Austria, Northern Italy, France, Great Britain, and Ireland are known.
