The Mycologic Flora of the Miami Valley, 0. 81 



Note. — It is hoped the preceding pages will prove a fair introduction 

 to the White-spored Agarics. This is the second effort, within the 

 writer's knowledge, to introduce the student to a systematic knowledge 

 of the Agaricini of an}' region of the U. S., the first being Prof. Chas. 

 H. Peck's Agaricini of New York State, in the Twenty-third Report of 

 the State Museum of Natural History. It is not to be expected that I 

 have found all the species, yet I have increased the list from :U in 

 Lea's Catalogue to 80. Compared with the corresponding number in 

 Mr. Frost's list of the fungi about Brattleboro, Vt., a region un- 

 doubtedly richer in this class of Fungi, there are in the latter 100 

 species of Leucospori. We will certainl}- make some additions, and 

 I hold in reserve some figures which as yet appear to me to be new 

 species. That I do not make some mistakes in the determination and 

 identification of species, would be to accomplish something that has 

 not yet been done in this country, even with flowering plants; but the 

 greater part of these plants have been seen by me before in the 

 Eastern States, and furthermore, specimens or figures of many of the 

 remainder have been submitted to the most competent authority in 

 this country-, Prof. Chas. H. Peck, the State Botanist of New York. 



These pages, and what may follow, are arranged according to the 

 Hymenomycetes Europtei, of the illustrious Elias Fries, of Sweden; this 

 arrangement accords also with the Handbook of British Fungi, by 

 Dr. M. C. Cooke. It is designed to introduce the student, through the 

 medium of our local flora, to a more extended knowledge of the 

 Hymenomycetes of North America, by means of the works above 

 mentioned, which are the most accessible to students. The specific 

 descriptions of Fries, which are models of perspicuity and elegance, 

 are translated with great care; such variations as may appear in our 

 species along with other general observations on locality and time of 

 growth, are made in appended remarks. The remaining Agarici will 

 form the subject of a second paper. a. v. m.
