 diameter, attenuated above, with the hemispherical, soon perforated 

 ostiolum erumpent and surrounded at the base by the thin margin 

 of the superficial layer of the perforated stroma : asci cylindrical, 

 230-320 x 35-40//, with abundant stout paraphyses, 4-8-spored : 

 sporidia uniseriate or subbiseriate, oblong-elliptical, subhyaline at 

 first with a broad hyaline envelope and a small tubercular or some- 

 times short-pointed appendage at the lower end, finally opaque, 

 45-60 x 20-22 p.. 



Melaxomma nitidum E. & E.

 what shining, minute (.2 5-. 3 5 mm.); ostiolum papilliform, minute, 

 soon perforated: asci cylindrical, short-stipitate, paraphysate, 

 8-spored: sporidia crowded-biseriate, fusoid, brown, 5 -septate, 

 scarcely constricted at the septa, slightly curved, tapering from 

 the middle to each obtusely pointed end, 2 5-3 2 x 5-6 /«. 



M. occidentale Ell. has perithecia larger, rough and only semi- 

 erumpent and sporidia not as distinctly attenuated towards the 

 ends and shorter.

 roughish, .5-75 mm. in diameter, with asmall papilliform ostiolum, 

 at length perforated: asci clavate-cylindrical, 75-85 x 1 2— 1 5 /" : 

 sporidia subbiseriate, clavate-oblong, hyaline, 4-septate, more or 

 less constricted at the septa, 18-22 x 6-8 /A 



ZlGXOELLA LOXICERIXA E. & E. 



On bleached limbs of Lonicera involncrata, Mt. Richtophen.

Perithecia scattered, suberumpent, .3 5-. 5 mm. in diameter, sub-
