d. Myxomycetes of Lake Winona.

With the advice and consoit of Dr. C. A. King, I decided to take the 

 time not reniuh-ed in teaching diu'ing the Station Session of 1902 in mak- 

 ing a systematic study of the Myxomjcetes of the lake neighborhood 

 and this report shows tlie result of the work. 



The season was one especially favorable for such a study, inasmuch 

 as the freiiuent waiin lalns were very coiuluciNe to a luxuriant growth 

 of all kinds of fungi. 



This list is liy no means complete, tliougli I fe(>l sure tliat it contains 

 the majority of the forms indigenous to tlie icgion. Had it been i)ossible 

 to continue tlie study for another niontli I fei-l sni-e tliat tlie list would 

 liave been very materially increased, for myxomycetes were as plentiful 

 at the close as they were at the opening of the station work. 



Quite a number of specimens were collected on special excursions to 

 Tiu'key Lake, Tippecanoe River, and North Manchester. I have included 

 in this list species found on those trips tliat I did not find at Winona. 

 The locality of such species is indicated in every case. All others were 

 collected in the immediate neighborhood of the lake. 



Dldijm'mm nUjripcs I found growing October 20, on Sphagnum that 

 I lirought to Clark University from the lake. On November 21 I noticed 

 the same species growing on ral)bits' dung that I had also l)rought from 

 t here. 



My first attempt was to follow the classification and nomenclature as 

 given in Lister's Mycetozoa. I soon found, however, that there are species 

 here not given in that work, and I therefore used McBride's Myxomy- 

 cetes of North Amei'ica in connection with it.
