L. sullivantii Mont, is probably tbe 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 ]\Iorg. 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- 

 nium sometimes obliterating the lamellae. Peck says that both 

 forms are sometimes found growing on the same stump ( ]\1. B.
