B. submoriformis, (Plowr.) 



Spktzyia submoriformis , Plowr. Grev. V, p. 74. 

 Bertia subnioriformis , Sacc. Syll. 2272. 



Perithecia irregular, rugose, ijursting through the cuticle, vari- 

 able in size. Sporidia biseriate, hyaline, simple, curved, 20-24x3 //, 

 uniseptate. This has much the appearance of B. moriformis, but 

 diifers in habit and in the sporidia being little over half as lai'gc as in 

 that species. 



On dead bai'k, California. 



The foregoing is from Grevillea, 1. c. Specimens on n dead 

 ;lieoch)? limb, Jrom West Chester, Pa., determined by Cooke as this 

 species (Grev. V, p. 74), have the perithecia subovate, more or less 

 rough, I mm. diam., or rathei- less, erumpent through the cuticle in 

 loose clusters of 2-6 together, or sometimes singly. Asci 75-80 x 12- 

 15 /i, with abundant filiform paraphyses. Sporidia liiseriate, broad- 

 fusoid, hyaline, uniseptate, 15-18x3-4 n, not curved. 



MELANOMMA. Fckl. 



SymboliE Mycol. p. 159. 



Perithecia gregarious or scattered, typically superficial, but some- 

 times erumpent-superficial, carbonaceous, mostly bare and black, 

 spherical or ovate. Asci cylindrical or clavate, 8-spored. S()oridia 

 oblong or fusoid, 2-or more-celled, brown.

Perithecia generally crowded, often forming a continuous layer of 

 considerable extent, but sometimes scattered, supei-ficial, irregularly 

 spherical or ovate, wrinkled or otherwise roughened, either sulcate or 

 smooth above, hard, black, 400 n diam., with a small papilliform ostio- 

 lum. Asci cylindrical or subclavate, stipitate, 8-spored, 80-100 x 6-9 a, 

 with filiform paraphyses. Sporidia uniseriate, oblong, narrowed towards
