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 (3). 



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 adoj)ted 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).
