 cavity opens on the surface of the branch naturally, only 

 a few conceptacles, if any, will show this narrow pore cut 

 through ; (3) the hairs or paraphyses which arise from 

 the wall of the cavity, and of which the upper ones 

 protrude through the pore ; (4) the densely granular 

 ellipsoid antheridia, borne on branching hairs ; (5) the 

 small-celled lining tissue of the cavity, which merges 

 towards the outside of the branch into (6) the compact 

 cortex, and towards the interior into (7) the loose medulla 

 of the branch.
