18 MUSCl-ACROCARPI-PERISTOMI. [Encalypla. 



1. E. streptocdrpa, Hedw. (spiral-fruited Extinguisher- Moss); 

 stems elongated, leaves elliptico-lanceolate somewhat obtuse 

 their nerve not produced beyond the summit, capsule cylindri- 

 cal spirally striated, calyptra toothed at the base. Hedw. Sp. 

 Muse, t. 61. Turn. Muse. Hib. p. 18. Fl. Brit. p. 1182.

Stony mountainous countries : upon mortared walls. In fruit upon 

 the walls of a bridge (since pulled down) in the grounds of the Duke of 

 Athol, at Dunkeld: near Lough Bray, Ireland, Mr. J. T. Mackay : and 

 in Derbyshire, J. E. Bowman, Esq. Fr. July. — The largest of the 

 genus; hence it may be distinguished, no less than by its rigid foliage, 

 spirally twisted capsule, and, above all, by its deep red very long com- 

 pact capillary teeth. The lid too is spirally striated, in which particu- 

 lar, as well as in the leaves, this moss has an affinity with Tortula 

 subulata. 



2. E. vulgaris, Hedw. (common Extinguisher-Moss); stems 

 short, leaves oblongo-elliptical obtuse their nerve produced a 

 little beyond the summit, capsule cylindrical smooth, calyptra 

 entire at the base. Hedw. Sp. Muse. t. 60. Turn. Muse. Hib. 

 p. 17. Fl. Brit. p. 1180. Drum. Muse. Brit. v. 1. t 22. Muse.

 Muse. t. 45. f 8. 



On banks, walls, and rocks, principally such as are calcareous : 

 not common in Scotland. Fr. March. — Teeth short and lanceolate, 

 exceedingly fugacious ; sometimes absent, according to Mr. Wilson, a 

 minute toothed border only appearing. That gentleman also finds a 

 variety with leaves having a blunt and rounded extremity, and an abbre- 

 viated nerve. 



3. E. ciliata, Hedw. (fringed Extinguisher -Moss); stems more 

 or less elongated, leaves oblongo- acuminate their nerve produced 

 considerably beyond the point, capsule cylindrical smooth, 

 calyptra with a distinct fringe at the base. Muse. Brit. ed. 2. 

 p. 63. t. 13. — a. concolor ; leaves apiculate their points of the 

 same colour. E. ciliata, Hedw. Sp. Muse. t. 61. Turn. Muse.

Bryum extinctorium, (3. Linn. Sp. PI. p. 1581. Dill. Muse, 

 t. 45. /. 9. — /3. pilifera; leaves much acuminated their points 

 diaphanous, (teeth of the veil deciduous). E. alpina, E. Bot.

 Moose, t. 8. n. 2. 



Not uncommon, both a. and |3., on moist rocks in mountainous dis- 

 tricts. Fr. Summer. — The fringe of the calyptra, in this species, is of as 

 thick a texture as the calyptra itself, and apparently set on to it with a 

 margin, thus not seeming to be a continuation of it. 



4. E. rhaptocdrpa, Schwaegr. (striated-fruited Extinguisher- 

 Moss); stems more or less elongated, leaves oblong apiculate
