Mnium hymenophylloides was described by Hübener in 1833 on 
specimens from Kongsvold, Norway, and shortly afterwards was 
discovered in the Alps of Central Europe. In 1846 the authors of 
the Bryologia Europæa described Mnium hymenophyllum as 
M. hymenophylloidi affine, diversum cæspilibus densis, elc.; 
remarking that it is distinguished from the latter by its dense 
tufts and its leaves less contracted at the base, decurrent and 
with a narrower margin. During the half century that followed” 
the two have been maintained as distinct without question, and 
indeed have been still more widely separated ; for Lindberg in his 
| Observationes de Mniaceis europæis (1868) places M. hymenophyl- 
lum doubtfully under Cinclidium, remarking that it appears to 
him to belong there rather than to Mnium ; that it inhabits moist 
ground, and has a very close resemblance except in colour to
