It is not pomble in painting to do juflice to the filvery appearance which this little rriofs ufually puts on, and 

 which in general obvioufly diftinguimes it from all our other Bryums, this lilvery hue it however lofes in fome 

 fituations and appears of a green colour, efpecially in moiff. fhelter'd places, where the leaves not only become 

 greener but laxer alfo and the furculi grow to a much greater length, in this ftate it is figured by Dillenius 

 as a diftindl: fpecies, the furculi vary much likewife in their fliape fometimes becoming very fine and almoff. 

 thread fhaped as reprefented at fig. 2. 3. 



The Bryum argenteum produces its Capfules as early as December and January, and this their early appear- 

 ance is one reafon why they are not not fo often found as fome others;, but "added to this it does not produce 

 fructifications fo plentifully as fome other Bryums, large patches of it being often found perfectly barren. 



It is very common on Walls and Banks.

This fpecies of Bryum is very commonly met with on Walls alfo on gravelly and fandy foils producing its 

 Capfules in February, March and April, it varies much in fize, in the fhape of. its leaves and the length of its 

 Surculi.
