Mycelium hypophyllous, superficial, sparingly branched, radiate, 

 with sessile, globose hyphopodia as in Asterina Leemingii, forming 

 orbicular spots 2-3 mm. diameter or more or less confluent. Perithe- 

 cia seated on the mycelium, ovate, 65-80//. diam. , pierced above, 

 black. Asci oblong, obtuse, aparaphysate, abruptly short- stipitate, 

 30-40x7-8//, 8-spored. Sporidia biseriate, oblong, 1 -septate and 

 slightly constricted at the septum, each cell nucleate, yellowish- hya- 

 line, 10-12 x 3-3 i,u. Some of the perithecia contain oblong, hya- 

 line, 2 nucleate stylosphores 6-7 x 3//.. 



This occurs on the same leaves as Asterina Leemingii E. & E., 

 but is distinct in its ovate, smaller perithecia and smaller sporidia. 

 This last named species was described as having the perithecia de- 

 pressed-globose, but they are really only convex or scutellate, and of 

 radiate-cellular structure. 



Hypocrea tenerrima E. & E. 



Spreading over mosses, decaying sticks, &c, Nuttallburg, West 

 Va., July, 1893. (L. W. Nuttall, No. 123). 



Perithecia gregarious, minute (& mm.), clothed (except the black 

 apex) with a thin white tomentum, seated on a thin snow-white, 

 tomentose- arachnoid subiculum. Asci cylindrical, 40x3//, without 

 paraphyses, 8-spored. Sporidia uniseriate, oblong, obtuse, hyaline, 

 5-6x2//, with a single nucleus in the center, (becoming uniseptate)? 



This is closely allied to H. subcarnea E. and E. , but differs in the 

 color of the subiculum, the black apex of the perithecia, the narrower 

 asci and rather longer sporidia. 



Hypocrea Virginiensis E. and E. 



On partly dead leaves of Rhododendron maximum, Nuttallburg, 

 West Va., August, 1893. (L. W. Nuttall). 



Epiphyllous, stromata carnose, scattered, sub-hemispherical or de- 

 pressed- turbinate, 1-2 mm. diam., of a yellowish gray color, subtrun- 

 cate above and obscurely margined (when mature). Perithecia 

 buried in the stroma, ovate, membranaceous, 110-150// diam. 

 Ostiola hemispherical, prominent, black, broadly perforated and 

 sometimes collapsed. Asci clavate- cylindrical, p. sp. 40-45x7-8//, 

 short-stipitate, filiform- paraphysate, 8-spored. Sporidia biseriate, 

 oblong- fusoid, yellowish-hyaline, uniseptate, slightly constricted at the 

 septum, obtusely pointed at the ends, 10-1 2x3-3 1 p..
