ascospores cylindric, nearly equally 4 septate, slightly con- 

 stricted, ends rounded, about 35x10/^. 



Two species of Meliola with branching setae have been 

 described as occurring on leaves of Piper from Ecuador, M. Pat- 

 ouillardi Gailard, and M. Pululahensis Gailard. The former 

 has also been reported on the stems (Bull. Soc. Myc. 8: 186). 

 Our specimens seem to differ sufficiently from this species in 

 the smaller capitate hyphopodia, setae and spores, and in the 

 absence of an ostiolum. It is also clearly related to M. fti7 cata 

 lycv., and some specimens on Piper have been referred to that 

 species.

HYPOCREALES. 

 Melanospora (?) Helleri sp. nov. 



Perithecia superficial, densely aggregated, 3 or 4 to 20 or 

 more on an indistinct basal stoma that penetrates the substratum, 

 large, one-half to two-thirds mm., deeply collapsed, grayish ex- 

 ternally from irregular flat, finally deciduous wart-like projec- 

 tions seemingly formed by the cracking of a hard outer layer; 

 substance of the perithecial wall of dark brown, soft, small-celled 

 parenchyma: ostiolum slightly papillate when young, but ob- 

 scurely perforate only when collapsed, the opening filled with 

 slender hyaline hairs: asci oblong, about 100x30^, soon evanes- 

 cent, paraphyses not seen: ascospores 8 (sometimes only 4), dis-
