224 BULLETIN OF THE BUSSEY INSTITUTION. 
No. 20.— Inst of Fungi found in the Vicinity of Boston. 
Part II. By W. G. Fartow, Assistant Professor of 
Botany in Harvard University. 
Tue present list, which is a continuation of article No. 23,* Vol. I., 
of the “ Bulletin,’ comprises species which have come under the 
writer’s observation, and which were collected either by himself or 
by persons connected with the botanical department of the University. 
Occasionally, reference is made to species which were found in parts of 
New England, remote from Cambridge. The species mentioned, it will 
be observed, belong principally to a few orders, — those in which the 
writer is especially interested; and the species of some of the orders 
poorly represented in the present paper will be considered at some 
future time. The list is followed by critical notes on some of the 
species mentioned in it, as well as on related species, which have been 
received from different parts of the United States.
