Tlie Agaricaceae of Ohio. 541 



L. sullivantii Mont, is probably the same as Clitocybe illu- 

 dens Schw. L. robinsonii Mont, is certainly not a Lentinus. 

 The pileus is said to be tubular at first, then cubshaped, the 

 lamellae are close, linear, long-decurrent. Probably a Canthar- 

 ellus. 



L. curtisii is L. omphalodes B. & C, not L. omphalodes Fr, 



L. ursinus and L. vulpinus have doubtless been confused in 

 America. Peck describes the former as being sometimes costate- 

 corrugate. This character is, in Europe, ascribed to L. vulpinus 

 only. 



With the meager description of L. pelliculosus it is difficult 

 to separate it from L. ursinus. It may be only a more hairy 

 form of that species — at least the Ohio plants referred to it. 



Lentodium squamulosum Morg. is often regarded as an 

 abnormal form of L. tigrinus. It may be recognized by the 

 mycelium or compact tomentum which grows over the hyme- 

 niyni sometimes obliterating the lamellae. Peck says that both 

 forms are sometimes found growing on the same stump (]M. B.
