to the ground; spermatia ovoid, very minute, produced on short, 

 indian-club-shaped spermatiophores, ckistered to form minute 

 spermadochia on decaying tissues, accompanying formation of 

 sclerotia. 



Apothecia shallow cup-shaped, stipitate, arising in the spring 

 from sclerotia in the soil or leaf-mold; asci cylindric; spores 

 hyaline, ovoid ; paraphyses simple or branched with swollen tips.

Conidia hyaline, often becoming 4-septate, straight or 

 curved, often breaking apart at the septa when mature, truncate 

 at the base, attenuated toward the apex, very variable in length; 

 about 6 n wide, borne on branched, hyaline, septate conidio- 

 phores which are densely clustered to form minute, white, 

 sporodochia which become horny and often amber-colored when 

 dry; sporodochia gregarious or scattered over both sides of the 

 leaf; usually most numerous on the upper surface; sclerotia 

 formed in the tissues of the dead leaves and stalks on the ground, 

 mostly along the veins, angular elongated, or circular, thin, 

 black, 3-5 mm. long, 1 mm. broad; spermatia accompanying 

 the formation of sclerotia, minute, ovoid, 1-2 X 2-3.6 /x, hyaline. 



Apothecia shallow cup-shaped, stipitate, arising from sclerotia 

 on or in the soil or leaf-mold, 1 /x mm. in diameter, pale fawn- 

 colored; stem tapering downward; asci cylindric, 8-spored, 

 reaching a length of 148 /x and a diameter of 10 m; spores ovoid, 

 hyaline, 5-6 X 10 16 /x; paraphyses slender, swollen above.

Sclerotia irregularly discoid to shallow cup-shaped, thin, 

 black, formed within but distinct from the host tissue; micro-

 hyphae forming tufts on the surface of the host accompanying
