UNREPORTED MICHIGAN FUNGI FOR 1009. 



C. H. KAUFFMAN. 



Through, the efforts of Dr. L. H. PenniDg1;ou, it is possible to include 

 in this years report a list of the Myxomycetes of the state. The her- 

 barium of the University was made the depository of quite a series of 

 Ann Arbor slime moulds, collected and studied by Prof. V. M. Spalding 

 and his instructor, Miss Fanny E. Langdon. during the yeai*s 1885 to 

 1895. Their collections were examined and verified or identified in 

 many cases by Prof. McBride, as noted in the list. L. N. Johnson and 

 A. J. Pieters were also active during; this period in adding specimens 

 to this collection. In recent years Dr. Pennington made a considerable 

 collection and has materially increased the number already in the her- 

 barium. He also examined and verified the list given below. 



The species of the other groups reported in this pai)er were collected 

 in various parts of the state. The dry season at Ann Arbor produced a 

 scanty crop of fungi, but this was offset by the moister conditions in 

 the Northern Peninsula. Miss Rose M. Taylor, located at Negaunee, 

 sent a large number of specimens collected in that vicinity, and from 

 these and my own collections from the same place later in the summer, 

 a number of plants new to the state, were obtained and are listed here.
