PRAECURSORES AD MONOGRAPHIA POLYPORORUM. 
By M. C. Cooke. 
( Concluded from p. 27.) 
The following additions and corrections should be made to the 
preceding lists, and a compressed synonymy is appended, in so 
far as it may be available for practical purposes. An extended 
and complete synonymy would involve considerable labour, which 
could scarcely be justified. As some of the species are distributed 
through the genera without our having seen authentic specimens, 
and on the faith of the descriptions, their position is subject to 
consideration. An arrangement of such an extent as this attempt 
could hardly be expected to attain perfection, which can only be 
secured by the co-operation of many minds. 
* Species Transferred. 
78 Polyporus glomeratus, Peck , to be struck out ; see Polystictus
