SPH^EIACEl. 851 



This can hardly be considered as a form of S. angustilahra, since that 

 species, even when the septa can be discerned, still remains quadri-nucleate. 

 The length is sliijhtly less, and the hyaline membrane absent. It appears 

 to succeed SphcEria conifonnis on old nettle stems, and has been overlooked 

 f: om its casual resemblance to the remains of the dispersing perithecia of 

 »Si. coniformis. {ViQ- 392.)

The Rev. M. J. Berkeley says that the typical form published by Fries in 

 Schromiicefes Suecice has sporidia of precisely the same shape, but twice as 

 long, and that he finds them sometimes "0028 in. long. *' It is distinguished 

 from the other wide-mouthed species by its short cylindric neck."
