Kalktålende underart der vokser i kalkholdig jord i dybe dale og i stensætninger med mørtel. Den adskilles sikrest fra ssp. trichomanes ved de større sporer (43 +/- 5 µm). Makroskopisk ved de mere tætsiddende, aflange, rektangulære, noget asymmetriske småblade, der ved det basale hjørne er fæstet til bladskaftet. Småbladenes overside har ikke ophøjede nerver. Den danske udbredelse er kun dårligt belyst, men arten må betegnes som sjælden. Den er kendt fra en grotte ved Skodsborg, fra et kirkedige i Vendsyssel og fra Lien i Hanherred, Nordjylland. Sjælden og fredet i Danmark.


Danish Redlist Status: DD (Data Deficient)
