reference to their structure and classification. It gives explicit 

 directions for their collection, an historical sketch of their location 

 in the system from the time of Vaillant (1719), a detailed account 

 of their morphology and anatomy and the development of their 

 * organs, and a synopsis of the species, which is to be followed by 



complete descriptions in the second part of the work. This 

 synopsis was prepared with the co-operation of Dr. O. Nordstedt, 

 and includes the discoveries down to September, 1887. To give 

 an idea of the number of species known, we note that North 

 America affords thirty-one species of Nitella, eight of Tolypella, 

 and twenty-eight of Chara, There is a still larger number of

 not been detected in America. Reference is made to the four 

 valuable sets of Exsiccatse distributed by the author, and a fifth

This is mainly devoted to the fungi, with descriptions of fifty- 

 seven new species, of whicii thirteen are figured. A synopsis of 

 the New York species of Paxillus, Cantharellus, Craterellus and 

 viscid Boleti is given, and the nomenclature of the New York 



, Pyrenomycetous fungi is revised to agree with the system of 



, Saccardo. The following phanerogams have been added to the 



State flora : Hieraciiim Pilosella, L., Atriplex hortensis, L., and 

 Rhodora Canadensis, L., the last collected in flower by Mrs.
