*Amlt>Iystegium Sprucel, B. & S. Leskia Sprucei Bruch. Dixon 

 and Jameson, Handbook of Brit. Mosses, Tab. 54, m. — Extremely 

 minute, forming small patches of a pale green colour; stems 

 filiform, very delicate, irregularl}' branched, fragile ; leaves distant, 

 erecto-patent, minute, less than a quarter of a line in length, ovate- 

 lanceolate on the stems, lanceolate-acuminate on the branches, all 

 narrowly acuminate, nerveless, margin plane or obsoletely denticu- 

 late or sinuolate, cells irregularly hexagonal-rhomboid, 2-5 times as 

 long as broad, pellucid, with firm walls, at basal angles slightly 

 wider and subrectangular, but not distinct. Seta very short, capsule 

 minute, erect or sub-erect, hardly curved, obovate, somewhat tur- 

 binate, inner peristome without cilia. Dicecious. The most minute 

 of our pleurocarpous mosses. On a damp bank among rocks, also 

 growing sparingly on rocks, in Correl glen. So far as I am aware, 

 this has not previously been discovered in Ireland ; it is very rare in 

 the North of England, Scotland, and Scandinavia.
