Encalypta.} MUSCI. 13 



1. S. sphcericum, LINN. fil. Leaves spathulato-rotundate, 

 acuminate, subserrated ; apophysis subglobose, wider than the 

 capsule. Linn. fil. et Swartz. Meth. Musc.t. I,/. 1. Muse. 

 Brit. ed. 2, p. 36, t. 9. 



On cowdung and the dung of other animals in the mountains. A 

 very common species, varying in the size of all its parts. 



2. S. mnioides, LINN. fil. Leaves ovato-lanceolate, much 

 acuminated, concave, entire : apophysis obovate, nearly as nar- 

 row as the capsule. Linn. fil. et Swartz. Meth. Muse. p. 6. 

 Muse. Brit. ed. 2, p. 38, t. 9. 



On the mountains near Belfast, Mr. Templeton. Near Bantry, 

 Miss Hutchins. Brandon Hill. In most specimens the teeth of the 

 peristome are by no means reflexed, in some erect, in others arched 

 across the mouth of the capsule. It varies in the size of the stem, of 

 the seta, and length of the capsule and apophysis taken together. 



3. S. ampullaceum, LINN. Leaves ovato-lanceolate, acumi- 

 nate ; serrated ; apophysis inversely flagon-shaped, much wider 

 than the capsule. Linn. Sp.pl. p. 1572. Muse. Brit. ed. 2, p. 

 39, t.9. 



Common in the mountains on cowdung. 



11. ENCALYPTA. Hedw. 



Seta terminal. Peristome single, of 16 teeth. Calyptra cam- 

 panulate, smooth, entirely enclosing the mature capsule. 



1. E. streptocarpa, HEDW. Stems elongated ; leaves ellip- 

 tico-lanceolate, somewhat obtuse ; their nerve percurrent ; cap- 

 sule cylindrical, spirally striated ; calyptra toothed at the base. 

 Hedw. Sp. Muse. t. 10, / 1018. Muse. Brit. ed. 2, p. 62, 

 t. 13. 



On stones at Dunkerron, county Kerry ; and elsewhere ; but without 

 fruit in Ireland. The lid is by no means so remarkably spirally stri- 

 ated as the capsule. The teeth of the peristome half as long as the 

 lid, are sometimes divided, and usually united at the base. The nerve 

 of the leaf is incurved at the summit. It has much the appearance of 

 Tortula subulata. 



2. E. vulgaris, HEDW. Leaves oblongo-elliptical, their nerve 

 excurrent ; capsule cylindrical, smooth ; calyptra entire at the 

 base. Hedw. St. Cr. I. t. 18. Muse. Brit. ed. 2, p. 63, t. 13. 



On limestone rocks, near Dublin and Cork. In specimens from 

 Cloghran, near Dublin, the lid had a setaceous rostrum ; moisture 

 having been carefully and long applied, the lid separated without being 

 torn from the mouth of the capsule, which exhibited, in the place of a 

 peristome, merely some irregular very short reddish processes, scarcely 

 to be distinguished from the mouth of the capsule. 



3. E. rhaptocarpa, SCHWAEGR. Leaves oblong, apiculate ; 

 capsule cylindrical, sulcate; calyptra ciliated at the margin, 

 cilia deciduous. Schwaegr. Supp. v. I. p. 56, t. 16. Muse. 

 Brit. ed. 2, p. 64. Supp. Tab. II.
