"Scattered, scai-cely visible externally. Asci large, clavate. 

 Paraphyses flexuous. Sporidia large, at first hyaline, consisting of 

 two subconical articulations placed l^ase to base ; one of these gi-adu- 

 ally increases in diameter and becomes very obtuse; a septum is then 

 formed at the base of the smaller articulation, and sometimes, though 

 rarely, there is a septum in the other cell. In every stage except in 

 extreme age, they have a gelatinous coat. Distinguished from M. in- 

 qulnans by the peculiar form of the sporidia, and especially in their 

 mode of formation." (Sporidia 48-54 x 19-23 (i, Winter).
