Cercospora Apocyni, E. and K. 



Living leaves of Indian hemp, Apocynum cannabinum. Whitehall. 

 August. The hyaline character of the hyphse indicate that the species 

 belongs rather to Cercosporella. 



Sporodesmium antiquum, Cd. 



Decaying wood. Flatbush. September. Zahriskie. 



Macrosporium PolytricM, n. up. 



Hyphae erect, septate, somewhat nodulose, colored, .003 to .004 in. 

 long, .0002 broad, forming continuous olive-green patches; spores 

 extremely variable, elliptical, oblong or clavate, colored, 2 to 9 sep- 

 tate, with or without longitudinal septa, .0008 to .0024 in. long, .0003 

 to .0006 broad. 



Capsules of moss Polytrichum juniperinum. Sevey. July. 



Stilbum Spraguei, B. & G. 



Dead stems of cabbage, Braf^sica oleracea. I^Ienands. August. 

 The spores in our plant are elliptical, .00025 in. long. The 

 receptacle becomes bay-red or chestnut color in drying. 



Isaria aranearum, Schw. 



On a dead spider. Manor. September. 



Our plant does not agree rigidly witH the description of I. 

 aranearum, bvit the differences appear too slight to warrant its separa- 

 tion. The club is paler with scarcely any incarnate tint. The spores 

 are very minute, .00012 to .00016 in. long, about half as wide. 



Tubercularia carpogena> n. sp. 



Keceptacle minute, depressed, glaljrous, subsuperficial, red; spores 

 oblong or subfusiform, straight or slightly curved, .0004 to .0005 .in 

 long, pointed at each end, produced on slender branched sporophores. 



Ripe fruit of blackberry, Rubus villosus. Menands. August. 



This appears at first sight like a minute species of Peziza or 

 Mollisia. It discolors the affected drupes, making them red like 

 itself. It is therefore easily overlooked. 



Fusarium Scleroaermatis, n. .sp. 



Sporodochia minute, convex, reddish -yellow or orange; sporojihores 

 somewhat branched, about as long as the spores; spores simple or 

 with two or three obscure septa, slightly curved, very acute at each 

 end, .0012 to .0018 in. long, ,00016 broad. 



On the peridium of Scleroderma vulgaris. Manor. September.
