302 The North American Cup-Fungi 



While this species usually occurs on PopuJus tremiiloides one 

 specimen from Canada was reported on Populus grandidentata. 

 Albertini and Schweinitz (Consp. Fung. 315) report this species 

 on Salix alba and on Fraxiniis. A specimen in the Ellis collec- 

 tion is accompanied by the following unsigned note: "Dermatea 

 fascicularis A. & S. Have found this again on ash; (you ques- 

 tioned its being an ash) when 120 was sent. Can this be a 

 different species?" Apparently Ellis questioned the host. 

 However we have in the herbarium of The New York Botanical 

 Garden two other specimens reported on ash both by reliable 

 collectors, one by S. H. Burnham at Hudson Falls, New York 

 the fungus determined by the writer and one by R. F. Cain from 

 Ontario, Canada, the fungus determinated by J. W. Groves. 

 The spores in those specimens on ash agree with those from 

 poplar so apparently this fungus is not restricted to Populus.
