d. Myxomycetes of Lake AVinona. 

 Fred Mutchlek. 



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

 time not required in teaching during tlie Station Session of 1902 in mak- 

 ing a systematic study of tliC Myxomycetes of the lake neighl)orliood 

 and this report shows tlie result of the work. 



The season was one especially I'avoralile for such a study, inasmuch 

 as tilt' frecjuent warm lains were very conducixe to a luxuriant growth 

 of all kinds of fiuigi. 



This list is Iiy no means i-omplete, though I feel sure that it contains 

 the majority of the forms indigenous to tlie region. Had it l)een possilile 

 to continue the study for another month I feel siu-e that the list Avould 

 have been very materially increased, for myxomycetes were as plentiful 

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



Quite a numlter of specimens were collected on special excursions to 

 Turkey Lake, Tippecanoe River, and North Manchester. I have included 

 in this list species found on rhose trips that I did not I'lnd at "NVinona. 

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

 collected in the immediate neighborhood of the lake. 



Di<hjuiiinii )ti(jriprs I found gTOwing Octol)er 20, on Sphagnum that 

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

 the same species growing on rabbits' dung that I had also brought from 

 there. 



My first attempt Ava>i to follow the classification and nomenclature as 

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

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

 cetes of North .America in connection with it.
