30° THIRTY-SIXTH REPORT ON THE STATE MUSEUM. 
peculiar variation in the species, and for these or other reasons are 
worthy of notice. New stations of rare plants, remarks and observa- 
tions are recorded in a section marked (8). 
Among the contributed specimens is a new species of edible fungus 
belonging to the genus Agaricus, subgenus Psalliota, and closely re- 
lated to the common edible mushroom, and its near relative the horse 
mushroom. The mushrooms are so interesting by reason of their fre- 
quent use as an article of food, and the three species mentioned are so 
variable and so intimately related to each other, that in pursuance of 
a plan already adopted in two previous reports (in which synopses 
of the subgenera Amanita and Lepiota have been given), I have 
thought best to give a full descriptive synopsis of all our New York 
species of the subgenus Psalliota. In this monograph the descriptions 
have been revised and made more complete, the dimensions of the 
spores have been given and copious remarks have been added with the 
design of pointing out more clearly the distinguishing features of the 
species and of aiding in their discrimination. It is marked (4).
