Dioicous ; resembling E. serratum, protonema paler, less dense, 

 becoming reddish-brown by age. Lower leaves lanceolate, upper erect, 

 oblongo-lanc. denticulate toward apex with projecting cells ; nerve soft, 

 vanishing at or below apex, cells at base hexagono-rectangular, above 

 hexagono-rhomboid. Caps, subglobose with a short point, brown, less 

 solid ; spores rough, brown. 

 Hab. — Moist banks ; very rare. Fr. 11 — 2. 



By the side of the River Shannon, near Portumna, Galway {Moon, 

 1865) ! ! 



The Irish plant quite accords with the American in its erecto-patent 

 leaves with slightly recurved points, and short upper cells, but the specimens 

 are poor and stunted, and only half the size of the foreign ones.
