Tufts large and compact, brown or green above. Stem elongate. 

 Leaves, when moist arcuate, ovate-lanceolate (shorter than in G. 

 trichophylla), recurved on both sides, generally hairless and obtuse, 

 sometimes with a short hair-point ; alar cells hyaline elongate in 45 

 rows, the other more or less erose. Perichetial leaves from the 

 sheathing base narrowed into a longer, canaliculate, sublinear (not 

 subulate) and obtuse acumen. Capsule nearly smooth, when dry 

 finally rugose, not distinctly costate ; teeth red, deeply cleft below the 

 middle, when dry, spreading, connivent when moist ; beak more or 

 less oblique ; pedicel arcuate when dry. 



This species is nearly allied to Grimmia trichophylla and very critical
