 no. 793 contains older, brown, 1-septate spores. The spores of 

 no. 792 measure 20-25 x 12-15 p, those of no. 793 22-25 x 10-15

 growth, exactly as in the next two species. (Fig. 10).

This is undoubtedly Diplodia Pinastri compressed by its un- 

 usual site. Growing on the bared wood of the root, it seems 

 to attack the cut ends of the rays, and assumes their outline, 

 but in every other respect it agrees with that species. I have 

 met with it besides on bark, leaves and cones of Pinus, preserv- 

 ing the same essential characters in each habitat. By observing

how it changes as it

S. Ellisii^ Sacc. (1884), Diplodia c&nigena, Desm., and probably 

 also D. pinea 9 Kickx, are all forms of the same species, to which 

 now Phoma micromegala must be added. The spores of D. 

 Pinastri are known to remain for a long time eseptate and nearly
