The Agaricaceae of Ohio. 531 



Notes. 



R. cyano'xantha, R. Integra, R. roseipes, R. adusta, R. pur- 

 purina, R. fragilis and R. nigricans have not been definitely re- 

 ported from Ohio as yet. Their range, however, makes it Hkely 

 that they occur here and they are included in the key for con- 

 venience in determination. 



Morgan reports R. lutea Fr. but from his notes it is evident 

 that his plants should be referred to R. fiavida which is rather 

 frequent in southwestern Ohio during some seasons. R. lutea 

 has not been otherwise reported and is omitted. 



Most American plants formerly referred to R. furcata are 

 now more properly referred to R. variata. It is uncertain at 

 present whether the true R. furcata occurs in Ohio.
