SACCARDO, SYLLOGE FUNGORUM.

a few hours. It may be that, upon closer acquaintance with 
the details, we may be able to trace species of which we find at 
present no indication in the “Index.” Under any circumstances 
this has been a weakness in the work, that the Index is very 
far from perfect, and we fear, from one or two trials, that where 
former volumes were weak the present is not strong. Never- 
theless, although it is quite possible that in some instances we 
shall not feel disposed entirely to agree with Professor Saccardo 
when we come to use the book for working purposes, we take 
no exception to the arrangement he has adopted, or the general 
manner in which he has carried it out, unless it be here and 
there a suspicion of more genera than seem to be necessary. 
A singular typographical error in the heading of the pages, 
commencing at page 239 and continued for fifty pages, is very 
misleading, and should have been avoided in a work of this 
kind, where so much depends on ready reference. 
COOKE’S HERBARIUM OF FUNGI. 
The whole of M. C. Cooke’s extensive Herbarium of Fungi 
has been acquired for the nation, and has been transferred to 
the Herbarium of the Royal Gardens at Kew, where it is in 
close proximity to the Herbarium of the Rev. M. J. Berkeley, 
which it even exceeds in numerical extent. It will be a source 
of gratification to mycologists that these two, the largest and 
most complete collections of Fungi ever made in this country, 
should have become public property, and may hereafter be con- 
sulted by Botanists from all parts of the world. The Herba- 
rium of the Rev. M. J. Berkeley will be maintained distinct, 
but the other is in course of incorporation with the General 
Herbarium of Fungi. 
FIGURES OF CORTINARII. 
A good opportunity now presents itself for mycologists who 
are specially interested in the species of the large and difficult 
genus Cortmarius , to commence taking the “ Illustrations of 
British Fungi ” from part *42 onwards, by which means they 
will obtain figures of Cojprinus and Gortinarius. Those for 
whom the entire work may appear too extensive and expensive, 
may obtain this portion, which will not exceed a single volume, 
and thus far it will be complete in itself, although the plates 
are numbered consecutively in continuation from the earlier 
portion of the work. Good figures are indispensable for the 
successful study of the species of this large genus, which will 
commence with part 44, as Cojprinus commences with part 42, 
and occupies two parts.
