Amphigenous ; niycelia persistent or evanescent, thin, filmy; 

 hyphae filamentous, colorless, branching, septate, 3-4 /x across; 

 perithecia gregarious or scattered, spheroid or depressed-spheroid, 

 /O-icO/ix diam. ; perithecial walls membranaceous, dark-brown, 

 composed of cells 10-18 /x wide; appendages 16-20 altogether, 

 delicate, filiform, straight or infiexed about the middle, continu- 

 ous, glabrous, equally thickened, spirally helicoid at the apex. 150- 

 440 X 6-7 /a; asci 6-8 in one perithecium, ellipsoid or ovoid, uni- 

 cellular, hyaline, one or two nucleate at the middle, 15-20X9-

Localit}- and distribution : Not given. 



Figures (woodcut) give the shape of appendages. 



Differs from the type by having ( i ) amphigenous and much 

 smaller perithecia, (2) very long appendages measuring 1.5 to 4 

 times as long as the perithecium and in numbers and dimensions of 

 asci and ascospores.
