THE DISCOMYCETES OF THE MIAMI VALLEY, OHIO. 
BY A. P. MORGAN. 
The collections of several years enable me at this present 
time to increase very considerably the list of the species of Dis- 
comycetes growing in this region, since the publication of Lea’s 
Catalogue in 1849. Many specimens have been sent to Chas. H. 
Peck, the State Botanist of New York, and many also to Mr. 
J. B. Ellis of New Jersey. Upwards of sixty numbers were sent 
to George Massee of the Royal Herbarium, Kew, England; these 
were chiefly small Pezizeae not figured in Cooke’s Mycographia. 
Among these Mr. Massee detected several new species which he 
described and figured. I have also^ profited much by the papers 
published recently by Mr. Massee, in the Journal of the Linnaean 
Society and entitled “Redescriptions of Berkeley’s Types of 
Fungi.” 
The classification of the Discomycetes is as yet tentative; no 
two writers divide the order similarly into families and genera. 
Hence in making up only a catalogue, I have been obliged to 
survey critically the nomenclature. In doing so I have indicated 
my notion in regard to genera and species; in many places I have 
suggested the correct writing of the specific names, on the ac¬ 
cepted principle of priority; and I have also been able to describe 
the spores and give the spore measurements of some of de 
Schweinitz’s little known species.
