"It is remarkable for bursting extremely raggedly, and having a 

 number of holes in it, at first sight looking very much like insect

Among moss on the stem of a beech. England (Berks). 



The Rev. M. J. Berkeley, F.R.S., has described a plant from Arctic 

 America which he considers to be identical with the present species, 

 which has not been recognized in England since Sowerby's time. 

 " About the size of a hazel nut. Precisely the plant of Sowerby, except 

 that his species is figured with a spurious stem. It is clearly no 

 Bhizopogori as asserted by Fries."— M. J. B.
