lunate, like those of Fnsariiun, acute at each end, 5-septate, mostly 

 nodulose and hyaline, 40 x 5-6 p.. Unfortunately in an immature 

 condition. 



On dead grass. California (Harkness). 



HYPONECTRIA, Saec. 



Syll. IT, p. 455. 



Perithecia covered, otherwise as in Nectria. 

 H. Gossypii, (Schw.) 



Sphcsria Gossypii, Schw. Syn. Car. 207. 



Hyponeclria (?) Gossypii, Sacc. Syll. 4582 and Cke. Syn. 542. 



Scattered, rather soft, immersed. Perithecia globose, purplish 

 flesh-color. Ostiolum elongated to the surface and discharging gelat- 

 inous matter. The minute perithecia are deeply sunk in the substance 

 of the immature capsules so as not to be visible outwardly, but, through 

 the elongated ostiola, a gelatinous substance is discharged, which 

 hardens on the surface of the matrix and gives it a purplish color. 

 In the mature specimens the surface of the capsules is granulose or 

 papillose from the subjacent perithecia. 



On dead capsules of the cotton plant, So. Carolina (Schweinitz). 



We have seen no specimens of this species, but have received 

 from Prof. F. L. Scribner a Fitsarhun on capsules of cotton, from 

 South Carolina, which may be the conidial stage. 



HYPOMYCES, Fries. 



Summa Veg. Scand. p. 382. 



Perithecia gregarious, with a cottony stroma in which they are 

 more or less immersed, mostly parasitic on various Hymenomycetes or 

 Discowycetes, bright colored, with papilliform or slightly elongated 

 ostiola. Asci mostly cylindrical, 8-spored, without paraphyses. Spo- 

 ridia oblong or fusoid, uniseptate, hyaline. Conidial stage represented 

 by Asteropliora, Sepedonimn. Dactyliiun, Verticillium &c. 



A. Sporidia continuous. 



H. Van Bruntianus, Ger. Bull. Torr. Bot. Club, IV, p. 64. 



Perithecia globose, densely crowded, pallid, hygrophanous, im- 

 mersed, with a short, thick, exserted, obtuse ostiolum; subiculum 

 white. Sporidia oblong, hyaline, shortly apiculate at the broad end, 

 gubobtuse at the other, 14-16 x 3J-4J //. Asci cylindrical. 



On the pilcus, stipe and gills of an unknown Agaric, Pough- 

 keepsie, X. Y. (Gerard), Iowa (Holway).
