Notes. 



Plants collected In- W. A. Kellerman were determined by 

 A. P. Morgan as H. repandum which is given by Fries and Sac- 

 cardo as a variety of H. sinapizans. Kellerman's photograph 

 (Mycological Bulletin 5:364) shows the stipe to be stuffed and 

 hollow. In the European plant the stipe is said to be somewhat 

 solid. 



H. glutinosum and H. crustiliniforme have not been definitely 

 reported for Ohio but probably occur here. They are includec? 

 in the key for convenience.
