Dermea 351 



8-spored, reaching a length of 80-90 m and a diameter of 10-12 n; 

 spores broad-elHpsoid, 5-6 X 7-8 m, usually containing one 

 large oil-drop; paraphyses filiform, thickened above. 



On lower surface of balsam leaves, Abies balsaniea, while 

 still on the tree; also on leaves of Pinus rigida. 



Type locality: Summit, New York. 



Distribution: New York and (New Jersey?). 



ExsiCCATi: Ellis, N. Am. Fungi. 385. 



Type material of this species has been examined. It has all 

 the appearance of a Pezicida except that the spores are small 

 with no indication of septa. The type material is abundant.
