The bright yellow epiphyllous discolorations of this fungus 

 were very conspicuous during the late summer in all patches of 

 the host, not only here but in other sections of the state.

On dead stems of Ambrosia trifida L., The Bronx, New York 

 City, March, 1907. G. W. W. 



This species is rather common in the vicinity of New York on 

 herbaceous stems, but is easily overlooked on account of the 

 inconspicuous habit and the peculiar hypha-like spores which are 

 25-30 X 1-2 /*.

The synonymy of this species is very much involved and the 

 fungus apparently very poorly understood.

During the latter part of the summer it was almost impossible 



to find a plant of this host which was unaffected with the fungus.
