Both forms are usually associated together. Messrs. Tulasne consider 

 them as a minor condition of Valsa suffasa, to which we are at present un- 

 willing to a-sent without further evidence. The sporidia in the polysporous 

 form are ( 000G-'0007 in.) ■01o-'0177 m.na. long, and in the octosporous form 

 (•000~--0003in.) -0177- 02 m.m. long. 



% Spjoridia mostly fusiform, 4-nucleate or multiseptate, hyaline.

Sphgeria." 



Perithecia very small, punctifurm, just penetrating the bark 

 with their minute ostiola ; sporidia biseriate, colourless, sub- 

 fusiform, wide in the centre, sides flexuous, usually elongated at 

 each end into a hyaline, mucronate appendage, quadrinucleate.
