of which are represented by duplicates in the Ellis collection, 

 but, except for a few station bulletins on economic species, there 

 is no local literature bearing on the fungi of the state. 



Pennsylvania. 

 Miihlenberg included a list of over two hundred species as 

 early as 181 3, and later Schweinitz collected extensively near 

 Bethlehem and reported many fungi therefrom in his later work, 

 Michener also collected and exchanged with Curtis and many 

 of his specimens thus found their way to the Berkeley collection 

 now at Kew. Later collections have been made by Dr. Martin, 

 B. M. Everhart, Haines, Gentry and Stevenson, most of which 

 are represented by duplicates in the Ellis herbarium. Dr. George 

 Ar Rex, of Philadelphia, also collected many fungi and gave 

 particular attention to the myxomycetes, on which he published 

 several valuable papers. His voluminous correspondence with 

 Mr. Mor^jan contains a mine of the most valuable notes on this 

 group, often accompanied by exquisite drawings. His untimely 

 death was a great loss to American mycology. Harold Wingate 

 also collected, in this group, largely about Philadelphia. While 

 descriptions of many species from Pennsylvania may be found 

 in widely scattered publications, the number of papers relating 

 primarily or mainly to Pennsylvania species is very small : 



Ellis. New Species of Fungi. Bull. Torrey Bot. Club, 10 : 

 -j^, Tj, 89, 90, 97, 98, 117, 118. 1883. 



Describes twenty-nine species partly from Pennsylvania. 



Muhlenberg. Catalogus Plantarum Americae Septentrionales. 

 Pp. 112. Lancaster, Pa., 1813. 2d ed., 1818. 

 List of 201 fungi mostly from Pennsylvania. 



Schweinitz. Synopsis Fungorum in Americae Boreali media 

 digentium. Trans. Am. Phil. Soc. 4: 141-316. PL ig. 1834. 

 3098 species included, partly from Pennsylvania. 



Rhode Island. 



The fungi of Rhode Island were early collected by J. L. Ben- 

 nett and S. T. Olney and were largely sent to Curtis and Berke- 

 ley for determination; a summary of some 580 species has been 

 pubhshed which includes practically all that has been done as yet
