able keys to such difficult groups as the Gasteromycetes, 1908, the 
Russulas, 1909, the genera of Asycomycetes and Basidiomvcetes, with a 
field key to the species of the Polyporaceae, in 1911. At present Id*. 
Kauffman is completing a monograph of the Hymenomycetes of Michigan 
to be published by the Michigan Geological and Biological Survey. 
Following the lead of Longyear, Pollock and Kauffman, ’05, listed the 
specimens found in the University of Michigan Herbarium adding 
whatever of records they themselves could. This list included the Fungi 
Tmperfecti (Pollock), the Ascomycetes and Basidiomycetes (Kauffman). 
The Phycomycetes were not included, nor were the Rusts and Smuts. 
A partial list of the Phycomycetes was added by Kauffman in a latter 
list, 1900. The only article on the Uredineae of the state was written 
by Miss Harriet L. Morrow an instructor in Botany at the University, 
but this was published only in abstract in the First Report of the Mich- 
igan Academy of Science. Miss Morrow besides this list of the Uredi- 
meae supplied many speciments to various exsiccati. Various students 
of Dr. Beal added specimens to the M. A. C. Herbarium and in 1900 
Bronson Barlow was employed to collect plants in the Upper Penin- 
sula. 
Michigan is but seldom mentioned in the general literature of 
Mycology and Plant Diseases. This is due entirely to the fact that re- 
ports for the state before the publications mentioned above, were very 
meager and scattered. Underwood, ’99, states: “In this state no local 
publications aside from some notices of a few economic species have been 
issued although collections have been made by Professors Wheeler and 
Spalding, Mr. G. H. Hicks and others. It is doubtful if there are one 
hundred species all told recorded in any publication as found in the 
state,” a very decided contrast to the condition of mycology in Wisconsin 
whose fungous flora has become Avell known and quickly available 
through the pioneer work of Dr. William Trelease and the continued 
efforts of d. J. Davis. 
Dr. Erwin F. Smith traveled extensively in Michigan while studying 
the diseases of peach, (chiefly yellows) from 1887 til! about 189”. The 
reports of his work on peach yellows are well known and are the classic 
on the subject. He reported other observations on various diseases in 
a series of Field Notes, ’90, ’91, ’92. These have been extensively quoted 
and are in many cases the first observations on the parasitism of a 
given organism. Further notes on the occurrence of plant diseases, 
especially bacterial diseases are found in later articles by Smith, ’05, 
’ll. 
Of course during the long period of agricultural and horticultural 
work by the College, many articles have appeared on plant diseases, 
but these records along with those from Horticultural Societies, articles 
in the farm press, etc., are difficult to find, to identify positively and to 
locate as to occurrence. For many years the Horticultural Department 
has issued spraying calendars, but these from their very nature are popu- 
lar and not intended for an exact report of species and localities. 
Two publications directly applied to Michigan conditions and found- 
ed for the most part upon observations of the authors upon Michigan 
diseases appeared in 1905. These were Longyear, Fungous Diseases of 
Fruits in Michigan, and Saekett, Some Bacterial Diseases of Plants
