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 diy and empty broadly 

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

 beak ; teeth ferruginous, broadly lanceolate, remotely articulate, 

 minutely cribrose. Male infl. 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. 11 — 12. 



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.

 a short, straight, or curved seta, more or less exserted, plicate or smooth,
