body. They .also suggest additional demands on the Club treasury. 
There is besides a growing desire among the members for a Club head¬ 
quarters, where the Herbarium could be kept together with a reference 
library, if the club ever has one, and where plants might be brought at 
certain times for identification and preservation. These considerations 
have induced the officers of the Club to make through the medium of this 
Bulletin an attempt to sound the wishes of the members in this matter. 
It is not proposed to increase the dues. But if it should seem wise to 
increase our expenses, the members who felt inclined would be asked to 
pledge themselves for perhaps three years to the annual payment of a 
certain sum. This plan is already in use in other clubs, and several 
members of the Mycological Club have expressed their eagerness to see it 
tried. If sufficient support of this suggestion comes through letters from 
the members, who are hereby invited to express their opinions, the neces¬ 
sary steps will be taken to put the plan in operation. 
The Secretary, then, hopes to hear from members on the following 
matters: correct address; collection of herbarium specimens; photogra¬ 
phic work; the subscription plan. His address is Box 21, Cambridge 
Mass. 
SACCARDO’S ARRANGEMENT. 
In answer to requests for a standard systematic arrangement of the 
genera of the Hymenomycetes, it seems useful to supply members of 
the Club with an abridged adaptation of Saccardo’s arrangement, drawn 
from the Sylloge Fungorum. 
This synopsis can hardly serve as an analytical key to genera, nor is it 
intended to do so, but it may be useful as a compact survey of the most 
easily observed characters. It will be thoroughly intelligible only to 
those who familiarize themselves with the full exposition of generic 
characters to be found in such a work as Stevenson or Massee, and who 
further make a careful study of generic types from the plants themselves. 
HYMENOMYCETEAE. 
Hymenium not an 
even surface, but 
on radiating lamellae. Agaricaceae I.

- or dense branches; plant tender. 
Clavariaceae V.
