Slender Rock Brake (Cryptogramma stelleri)
Slender Rock Brake (Cryptogramma stelleri)
The best way to disinguish slender rock brake from regular rock brake is the the ultimate segments are more open and not meeting in the center as seen here. The segment edges of regular rock brake are curled around to near touching. Photo from Pyramid Peak, Idaho.
