THE DISCOMYCETES OF EASTERN

 same season one very interesting specimen was collected in 

 Washington Park, Chicago, which is here described and which

In all nearly one hundred species belonging to this group 

 have been collected, the most of them in the vicinity of Iowa 

 City. Fifty of these, including the one collected in Illinois, 

 are described in this paper. Tbe remaining specimens col-
