Autoicous ; in short densely pulvinate tufts, lurid or blackish green 

 or sometimes yellowish above, fuscous black and interwoven with 

 rufous radicles at base. Leaves densely crowded, erecto-patent when 

 moist, curved and subtortuose when dry, narrowly linear-lane., muticous, 

 canaliculate-concave, with plane margins ; nerve thick, fuscous, vanishing 

 at apex or excurrent in a strong mucro ; cells lax and narrowly 

 rectangular at base, minute, indistinct, in 2 3 strata above. Perich. 

 bracts longer, broader, falcate when dry, subpilifero-acuminate. Caps, 

 pale brown, leptodermous, truncate ovate, when dry and empty broadly 

 turbinate ; lid yellow, large, convex, suddenly prolonged into a curved 

 beak ; teeth ferruginous, broadly lanceolate, remotely articulate, 

 minutely cribrose. Male inn. near the female, gemmiform, bracts 

 broadly ovate, shortly acuminate. 



HAB. Rocks by the sea. West coast of England, Ireland, and Scotland ; 

 less frequent on the east side. Fr. 1112. 



This moss grows in dense cushioned mats, and is much more rigid than 

 G. apocarpa, with a more prominent perichaetium, and all the leaves muticous. 

 It is found all along the coast from Penzance to Orkney.
