Pei'ithecia densely gregarioas, superficial, grayish-black, rough, 

 ovate-globose, 300-400;/. diani, with a broad papilliform, soon per- 

 forated ostiolum. Asci cylindrical, short-stipitate, 55-62 x 7-8//., 

 8-spored (paraphysate)? Sporidia uniseriate, short-elliptical, yellow- 

 ish-hyaline, obscurely 1— 3-septate and uiuriform, 10-12 x 6-8//. 



Has the general aspect of Roselliiiia pulveraeea (Ehr. ). 



Teichospora tuberculata E. & E. 



On vvoud of LIriodendron, Ohio (Morgan, No. 1,004). 



Perithecia gregarious, superficial, minute, about 300//. high and 

 200/'. broad, ovate-conical, sessile on the flattened base, coarsely 

 tubercular-roughened, black. Ostiohun obtuse, perforated and often 

 4-sulcate-cleffc. Asci ciavate-cylindrical, short-stipitate, 110 x 20//, 

 paraphysate, 8-spored. Sporidia irregidarly biseriate, oblong-ellip- 

 tical, multiseptate and muriforni, hyaline at first, tardily becoming 

 brown, slightly constricted in the middle, 19-22 x 11-13//., ends ob- 

 tuse. 



Distinguished from the other species by the ovate-conical, tubercu- 

 lar- roughened perithecia. 



Teichospora araygdaloides E. & E. 



On bark of Salix amygdaloldes, Rockport, Ks. , July, 1894 (Bar- 

 tholomew, No. 1,507> 



Perithecia scattered or sub-gregarious, erumpent-superficial, sub- 

 globose, 250-350/' diam. , soon flattened above and at length more 

 or less collapsed. Ostiolum papilliform. Asci subventricose, sub- 

 sessile, paraphysate, 8-spored, 75-85 x 18-21//. Sporidia mostly 

 crowded- biseriate, obovate, about 5- septate and constricted in the 

 middle, with a longitudinal septum running through 2 or more cells, 

 hyaline and uniseptate at first, finally yellow-brown, 20-22x10— 

 13//.. 



Differs from T. obdueen.^ (Pers. ) in its scattered gi'owth, sub-col- 

 lapsing and mostly rather smaller perithecia, and shorter asci with 

 crowded sporidia.

On bark of Ner/ioido aceroides, Rockport, Kansas, July, 1894 

 (Bartholomew, No. 1,509). 



Perithecia scattered, erumpent-superficial, ovate-globose, rough, 

 250-300// diam., with a pa[)illiform ostiolum. Asci ciavate-cylindri- 

 cal, 100-120 X 14-15/', paraphysate, 8-spored. Sporidia obliquely
