ing in the interstices a very tough white 



central fibre, which pervades the whole 



plant. The shields (a) are now and then 



to be found at the divarications of the 



principal branches, and nearly of the same 



colour : their margins radiate with rigid 



pointed fibres. This moss was formerly 



used as a styptic." (Eng. Bot., vol. iv.) 

 The other lichens that grow on the oak, 



says Mr. Borrer, are generally those that 



occur on other trees under similar circum- 

 stances of age, size, and situation. If a few of them have been observed on 

 the oak, or on oak wood only, they are among the most obscure, and on that 

 account extremely liable to have been overlooked elsewhere : such as Calicium 

 microcephalum Eng. Sot., t. 1865. ; C. hype- 

 rellum Ach., Eng. Bot., t. 1832.; Spiloma 

 punctatum Eng. Bot., t. 2472. ; S. fuliginosum

 in England ; but it has been found on oak trees in Rag- 

 ley Park near Alcester, at Himley near Dudley, and 

 in Rockingham Forest. It is of a cinnamon colour 

 when young, and whitish when old, changing, when 

 bruised, to a reddish brown. When fresh, it distils drops of moisture from the
