80 PottTY-THtRB AnNUA^ RePORT ON THE 



asci and spores are far more slender and somewhat longer than those 

 of the Eiu'opean plant as represented by Fuckel's figure and descrip- 

 tion. The globose termination of the ascus is at the apex, not at the 

 base as Ftickel has it. Because of these differences I have given a 

 figure of our plant and designated it as variety ccespitosa. 



Hypoxylon eflfusum, Nits. 



Decaying chestnut wood. Flatbush. September. Zabrif<kie. The 

 smaller spores distinguish this species from H. serpens. 



Eutypa flavovirescens, Tul. 

 Dead branches. Lyndonville. May. Fairman. 



Eutypella longirostris, n. sp. 



[Plate 4. Figs. 8 to 12.] 



Stroma suborbicular, convex, formed of the slightly changed sub- 

 stance of the bark, whitish, covered by a black crust, often somewhat 

 confluent in series; perithecia minute, globose, few or many in a stroma; 

 ostiola elongated, fasciculately crowded, straight or flexuous, often fully 

 one line long, radiately sulcate at the apex and sometimes sulcate on 

 the sides also, black; asci clavate, pedicellate, the sporiferous part .0007 

 to .0009 in. long, .00016 broad; spores minute, curved, .0002 to .00025 

 in. long. 



Bark of elm, Ulnius Americana. Sandlake. Peck. Syracuse. 

 Underioood. 



This is easily distinguished from the allied species by its very long 

 ostiola and its very short asci and spores. 



Anthostoma microsporum, Karst. 

 Dead bark of alder, Alnus incana. West Albany. May. 



Cryptosporella hypodermia, Sacc. 



Dead branches of sliiipery elm, Ulmus fulva. Copake Iron Works. 

 June. 



Leptosphaeria dumetorum, Messl. 



Dead branches of cultivated honeysuckle. Lyndonville. May. 

 Fairman. 



Herpotrichia rhodomphalia, Sacc. 



Decaying wood of locust, Rohinia Pseifdacacia. Yaphank. September. 



Lophiotrema auctum, Sacc. 



Dead stems of wild rose. Lyndonville. June. Fairman. 



The three following species are extra-limital and are not yet to be 

 included in the New York flora. Being considered new species it is 

 desirable that descriptions of them should be published.
