SPORORMIELLA, E. & E. nov. gen. 



Perithecia soft- earn osc. embedded in a flattish, semiimmersed, sn li- 

 ra rnosc sfroina. Asri and sporidia as in Sporonnla. 



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



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

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

 ^-1 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 sub tubercular, erumpent, perforated. Asci 

 rlavate-cylindrical, 100-125 x 10-12 JJL. Sporidia mostly biseriate, at 

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

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

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

 aphyses linear, nucleate.

Delitschia bisporula, (Croiian). 



Horniospora bisporula, Crouan, Fiuist. p. 21, 



Delitschia bisporula, Hanseii's Fuugfi Danici. p. 107, tab. IX, fig's. 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. TRICHOSPHMUEJ]. 



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 hyphae over- 

 spreading the matrix. 



VENTUR1A, Ces. & De Not. 



Schema d. Classif. p. 51, Sacc. Syll. 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.
