closely to allied genera that the line of separation is not always clear. It 

 has, therefore, seemed especially important to collate our species and 

 revise the descriptions and the arrangement in order to remove as much 

 as possible the difficulties attending their study. 



In doing this, the plan adopted in similar cases in previous reports has 

 been followed. An analytical key to the tribes has been given and also 

 one for the species of each tribe. The descriptions have been revised 

 and the spore measurements recorded. It is believed that these analytical 

 tables will greatly facilitate the tracing of any species to its proper place in 

 the system and to its description. Similar tables for our extralimital species 

 have been added. This monograph of the genus Collybia is marked E. 



In pursuing the investigations of our fungous flora and in testing the 

 edible qualities of some of our mushrooms, lo species have been added 

 to the list of those available for food. Samples of all of these have been 

 eaten by myself with pleasure and perfect safety, and I have no hesitation 

 in classing them as edible. Colored figures of these in natural size have 

 beea prepared on five plates of the same dimensions as those contained 

 in the last report and numbered continuously with them. Descriptions 

 of these species have been written on the same plan as those of the 

 edible fungi in that report, to which they properly form a supplement. 



By reason of the unpleasant experience of an esteemed correspondent 

 who is an enthusiast in mushroom experimentation, I am able to add a 

 plate and a description of an unwholesome species. Its quality is such 

 as to produce nausea and vomiting, but it is not fatal in its effects as 

 those are which are commonly denominated poisonous. After the sys- 

 tem has rejected the offending material it soon recovers its usual tone. 



These descriptions c^onstitute a part of the report marked F. 



A duphcate set of models of edible and poisonous mushrooms, repre- 

 senting 2 1 species, has been generously donated by the Department of 

 Agriculture at Washington to the New York State Museum. These 

 models are similar to those exhibited by that department at the World's 

 Columbian Exposition, and they will form an interesting and instructive 

 addition to the equipment of the Botanical Department of the Museum. 

 But space is lacking, in the room occupied by the Herbarium, for the 

 proper exhibition of these models. For the same reason a part of the 

 State Museum exhibit of specimens of fungi yet remains packed in boxes. 

 It is therefore desirable that, if possible, more ample space should be 

 assigned to the Botanical Department. 



Respectfully submitted.
