To obtain the color of the epore masses, a small mass of them was 

 placed in the bottom of the dish, so that the spores could be placed over 

 and naar the color blocks to get the colors. Thus the light was partially 

 transmitted, partially reflected. 



All the strains were similar in -that they readily induced a rotten 

 condition of the apricot fruits. Some however did this much more rapidly 

 than others. Strain 2, Westerdijk*s Sclerotinia cinerea. progressed 

 very slowly, in fact it was the slowest growing of all. Strain 5, 

 Oregon Sclerotinia cinerea. became established first and grew most rapidly 

 of all the strains. The other strains lay between these two extremes 

 with H tendency to approach 5 rather than 2, 2 remaining distinctly in a 

 class by itself as regarded the rate of growth. 



In the matter of type of growth there seemed to be four different 

 forms. 



(1) Prof us* somewhat loose spore puetwles. Strain 1 typical* 



(2) Profuse, comnact, f el ty -looking epore pustules. Strain 4 



i' 

 typical. 



(3) Abundant surface mycelium with very few spores. Strain 8 

 the only strain with this characteristic. 



(4) Scant surface mycelium with very few spores. Strain 2 the 

 only strain with this characteristic. 



Nearly all the forms resembled the first above. The second had 

 only two representatives, tha third and fourth one representative each. 

 There seemed to be three different epore colors: 



(1) Cartridge buff (H) 

 (2) Grayish olive (ft) 

 (3) Drab - a little lighter than Saccsrdo's drab.
