HYPNACE.E.] 132 [Myurella. 



This elegant little moss was confused hy C. Mueller with Clasmatodon 

 parviilns (HAMPE) SULUV. and called by him Neckera fcrpnsilla Synops. ii, 666, 

 and Schimper in the .Bryol. Eur. also united them under the new name 

 Anisodon pcrpusillus. The two plants are very much alike, but differ sufficiently 

 in the fruit to represent two genera. The headquarters of our moss are in 

 Italy, where it grows on olive and orange trees and fruits freely, and it is 

 reported to have been found with young fruit at Finlarig, near Killin, by 

 McKinlay. It still exists on the plane tree in front of Killin hotel, where 

 Schimper detected it. 



Subf. 3. STEREODONTEyE. Plants small or tall, stems creeping or 

 ascending, vaguely or pinnately branched, sometimes dendroid. Leaves 

 compressed or equal on all sides, with two nerves or nerveless, the cells narrow, 

 smooth, or projecting at apex, the basal angular often short and dense. Capsule 

 inclined or cernuous, lid often with a short beak, processes of endostome rarely 

 perforate, with or without cilia. 



A. THELIE.E. Plants slender, Leskeoid in habit, the leaves papillose. 



It is unfortunate that on account of the difference in neuration, this group 

 should be separated from the Leskeas, with which they have the most natural 

 affinity. In TJielia the leaves have ciliated margins. 



12. MYURELLA BY. Sch. 



Bryol. Eur. fasc. 46 47 (1851). 



Plants very small and slender, densely tufted, with fragile julaceous 

 stems, often stoloniferous, and few erect branches. Leaves crowded, 

 imbricated, rounded or ovate, very concave, nearly smooth or papillose at 

 back, nerves two, very short, or none. Calyptra cucullate. Capsule 

 suberect, oval ; teeth of peristome lanceolate-subulate, endostome with a 

 high basal membrane, . processes lanceolate, cilia short binate. Der. 

 Named from resembling a mouse's tail. 



CLAVIS TO THE SPECIES.
