"Perithecia immersed, obtusely papillate and at length Bubpromi- 

 nent, 200-225 /j, diam. Asci cylindrical, 56x4 fi. Sporidia didy- 

 mous, upper cell globose (4 //), lower cell subovate, 4x 3 jjl, hyaline." 



Specc. on bark of decaying (maple?) limb on the ground, New- 

 field, N. J., have (stroma?) 2 cm. high, clavate, leather-color. Only 

 two specimens were found, and those were immature, so that the fruc- 

 tification could not be made out, though the surface of the club wrae 

 finely punctate from the ostiola of the immersed perithecia. Accord- 

 ing to Tulasne & Broome, the club-shaped body, on the upper part of 

 which the perithecia are borne, is not a true stroma, but either 

 Clavaria ligula or Spathularia flavida bearing 4he Hypocrea as a 

 parasite. 



The following species are imperfectly described:

"Forming a thin, black stratum on the under side of the leavi 

 grasses in Cuba, and of Andropogon in Alabama. Perithecia globose 

 and, with the ostiola, immersed. Sporidia filiform. (See p. 91). 



H. parasitans, B. & C. Grev. IV, p. 15. " Minute, pallid, subcllip- 

 tical, sometimes winding around the teeth. Sporidia globose, rather 

 large." On Hydnum erinacewm, South Carolina. 



H. subviridis, B. & C. 1. c, "Effused. Perithecia pale dull green, 

 tomentose, crowded, seated on a white mycelium. A curious species."

Sphczria sterilior, Schw. Syn. N. Am. 1188. Hypocrea sterilior, Cke. Syn. 168. 



Substance at first very soft; broadly effused, applanate. surface 

 longitudinally striate, flesh-color, becoming light yellow when dry. 

 Hie margin is very delicate, cottony, with interwoven fibers with 

 which the whole surface appears lightly covered. Texture carnoee, 

 becoming horn-like when dry. Perithecia few, scattered.
