 elliptical, 4-celled, appearing obscurely 3-septate, hyaline, 12-15 x 6J 



On dead stems of Hamulus lupulus, Carlise, N. Y. (Peck). 

 The perithecia have a dull, squalid, unpolished or subscabrous 

 appearance. 



Z. subvestita, (E. & E.) 



Spharia subvestita, E. & E. Journ. Mycol. II, p. ioo. 

 Zignoella subvestita, Sacc. Syll. 7495. 



Perithecia seated on the bare wood or on the bark, with the base 

 sunk in the matrix, ovate-conical, 165-250 /i diam., J mm. or more 

 high, black, rough, except the smooth, subshining, short-cylindrical or 

 subcorneal, broadly perforated, subtruncate ostiolum. Asci clavate- 

 cylindrical, 50x6-7 /^, with filiform paraphyses and a slender, stipitate 

 base. Sporidia fusiform, yellowish-hyaline, slightly curved, 3-septate 

 and constricted slightly at the middle septum, 12-15 x 2-3 /i, crowded- 

 biseriate. The sporidia are much the same as in Clypeosphceria Hen- 

 dersonice, Ell., except in having the ends slightly curved, but in that 

 species, the perithecia are depressed, subcuticular and subastomous. 

 Zignoella conica, (Fckl.), has much larger sporidia (28x4 //.). 



On drv, bleached roots of Vaccinium, Newfield, N. J. 



FAMILY. CERATOSTOMEiE. 



Stroma none. Perithecia superficial, or at first immersed and 

 finally erumpent, with an awl-shaped or at least more or less elongated 

 ostiolum. Texture thin-membranaceous, or sometimes subcoriaceous. 

 Asci mostly very evanescent, with the membrane thickened at the apex. 

 Paraphyses generally present. 



The most obvious character of this family is the elongated (subu- 

 late, cylindrical or conical) ostiolum. It is distinguished from the 

 Gnomoniece by the superficial or erumpent perithecia, and the presence 

 of paraphyses. 



Ceratostoma, Fr. Obs. II, p. 340. 



Perithecia more or less superficial, with a distinct, and generally, 

 strongly developed beak; substance firm, coriaceous or carbonaceous. 

 Sporidia ovate, oblong or elliptical, brown, continuous.
