 268 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



leave the remaining species of Lachnocladium clearly in the 

 Clavariaceae. 



I include Lachnocladium for reference by students of the 

 Thelephoraceae because some authors have regarded it as a mem- 

 ber of the latter family. 



Collectors' field notes on whether the species are coriaceous 

 or fleshy at the time of collecting are necessary for sharply 

 separating Lachnocladium and Clavaria, for it is evident that 

 these characters may not be well shown in the case of dried 

 specimens of some species.
