UNREPORTED MICHIGAN FUNGI FOR 190G. 



C. H. Kauffman. 



The additions to our mycologicai flora for the year were mostly obtained 

 in the upper peninsula. The species mentioned, along with a great many 

 plants previously reported, were the result of a ten weeks' stay at various 

 points along Lake Superior. Sault Ste. Marie, Houghton, Isle Royale, Mar- 

 quette and Munising were made the bases around which the collecting was 

 (lone. Special attention was paid to the Basidiomycetes, and this, with a 

 season that was drier than the average, accounts for the few reports of other 

 groups. 



A considerable number of plants remain undetermined, and will have to be 

 reported later. As in my previous annual reports, no effort is made to 

 give the synonymy; it is assumed that the only possible starting point for a 

 report of this kind is to determine by thebest methods within reach whether 

 the plant in question is the one considered so by the author who named it; 

 whether other authors had named it before is a cjuestion outside of our im- 

 mediate interest in making out these reports, and assuming that our diagnoses 

 under these conditions are correct, we refer to another place or to other men 

 the task of unraveling the S3ai0nymy. 



A fuller account of the whole flora of this region will be given in connection 

 with a report to the State Geological and Biological Survey, under whose 

 auspices the work was clone.

 C. H. Peck lent his aid in his usual generous manner.
