from year to year. There is also a plot of about four acres on 
the University farm planted about eight years ago with various 
young forest trees. All of these young trees had been liberally 
mulched yearly, from the time of planting, with a fertilizer com¬ 
posed of equal parts of shavings and dung, and it was in and be¬ 
neath this mulch that the fungi were most abundant. 
So numerous were the plants on the entire region that for a 
period of six weeks specimens could be found every day. As 
many as two dozen were often taken on a single morning. Prob¬ 
ably as many as three hundred specimens were handled during 
the season. These were examined and types of all sizes and pro¬ 
portions were carefully measured and then preserved by drying 
or in alcohol. When it was desired to get a series of plants be¬ 
longing to the same mycelium, certain clusters of the eggs were 
marked and specimens gathered from day to day as they matured. 
In making the measurements it was aimed to secure speci¬ 
mens showing all possible variations. The following table gives
