SPORORMIELLA, E. & E. nov. gen. 

 Perithecia soft-carnose, embedded in a flattish, semiimmersed, sub- 

 camose stroma. Asci and sporidia as in Sporormia. 



S. nigropurpiirea, E. & E. (in Herb.) 



Perithecia globose or slightly ovate-globose, about \ mm diam., 

 thick-walled, soft, and' buried in the soft, flattish stroma, which is 

 \-l cm. across, or by confluence more, slightly raised above the surface 

 of the matrix, dark gray outside, and, like the perithecia, purplish- 

 black within. Ostiolum subtubercular, erumpent, perforated. Asci 

 clavate-cylindrical, 100-125 X 10-12 /z. Sporidia mostly biseriate, at 

 least above, cylindrical, nearly straight, 4-jointed, hyaline at first, soon 

 dark brown, 1 6-20 x 4-5 ii, terminal joints subovate, intermediate ones 

 subglobose, about 4 ^ diam. Asci with a short, narrow stipe. Par- 

 aphyses linear, nucleate.

Delitschia bisporula, (Crouan). 



Hormospora bisporula, Crouan, Finist. p. 21. 



Delitschia bisporula, Hansen's Fung;i Danici. p. 107, tab. IX, figs, 7-11. 



This species has been figured (Plate 17) to illustrate the genus, 

 though, as far as we know, it has not yet been found in this country. 

 Delitschia may be briefly characterized as a Sordaria with uniseptate 

 sporidia. 



FAMILY. TRICHOSPHiERIEJl. 



Perithecia from the first superficial or erumpent, without any 

 stroma, coriaceous or membranaceous, or sometimes subcarbonaceous, 

 generally clothed with bristles or hairs, often with a more or less 

 strongly developed, felt-like layer of conidia-bearing hyphs over- 

 spreading the matrix. 



VENTURIA, Ces. & De Not. 



Schema d. Classif. p. 51, Sacc. SyU. I, p. 586. 



Perithecia superficial or erumpent, bristly, ostiolate, membrana- 

 ceous. Asci sessile or briefly stipitate, 8-spored, mostly without par- 

 aphyses. Sporidia oblong or ovoid-elliptical, uniseriate, hyaline or 

 yellowish, mostly foliicolous. 



Coleroe, (Fr.), which comprises only species with strictly super- 

 ficial perithecia, is here included in Venturia.
