Dioicous; laxly csespitose, plane, olivaceous or squalid -green, 



slightly canescent at tips. Stems slender, somewhat elongated, naked 



below, sparingly fastigiate-branched. Leaves erect when dry, divaricate 



and patulous when moist, longly lane, acuminate with acute hoary 



dentate points, lower muticous, towards base carinate-concave with 



reflexed margins, above subcomplicate ; cells in one stratum, at base 



sinuoso-rectangular, with a row of broader quadrate ones at margin, 



above roundish-quadrate with i — 3 rows at margin bistratose, the nerve 



stout, flattish at back. Perich. bracts sheathing, more laxly areolate, 



with the nerve vanishing. Capsule on a short yellowish seta, erect, 



very small, elliptic, light brown, olivaceous when young, leptodermous ; 



calyptra mitrseform, nearly smooth at apex, lid acutely rostrate, f length 



of caps., annulus broad, of 4 rows of cells, rolling back, teeth more or 



less bipartite, red, erecto-patent when dry. Male plant more slender, 



bracts ovate, acute. 



Hab. — Moist alpine rocks. Fr. 4 — 5.

This species as well as G. elongata having straight setae are removed from 

 the G. trichophylla group, to which in their sterile state they would undoubtedly 

 be referred, for G. microcarpa has in no form the pecuhar ramification of 

 Trichostomum, though its sinuose-crenulate cells represent those of that 

 section. Grimmia affinis has the greatest resemblance to it, but in G. microcarpa 

 the leaves have much narrower points, and the lower cells are shorter and 

 wider.
