TJie Agaricaceae of Ohio. 511 



G.^ Stipe cinereous ; lamellae somewhat 

 decurrent. S. 295; St. 145; H. 

 129; A. 97 M. vulgaris Pers. 



Notes. 



M. lilacina Mont., described from Sullivant's material (S. 

 257), is a doubtful Mycena. The pileus is said to be lilac-col- 

 ored and umbilicate ; the lamellae remote (when dry) and rosy- 

 ochraceous. The plants ma}^ possibly have been M. pura. the 

 abnormal character appearing in drying. 



Neither the above nor M. cymbalifera nor M. conferrumi- 

 nata have been recognized since described. 



M. vitrea and M. vulgaris have not been definitely reported 

 from Ohio but probably occur here and so are included.
