Species Causing Decay of Vegetables 
Plate 
Cultures of Sclerotinia libertiana, S. intermedia, and S. minor on potato-dextrose agar plates, show 
ing differences in rate of growth at 7° C. and 20° 
A —S. intermedia (above) and S. minor (below), planted together, and held at 20°. S. intermedia 
did not form any sclerotia, and its growth was slow in comparison with S. minor 
B—Two strains of S. intermedia, planted together, and held at 20°. The strain from salsify 
(above), and the strain from carrot (below), grew at equal rates and met in the center of the plate, 
each forming sclerotia 
C. — S. intermedia (above) and S. libertiana (below), grown together, at 7°. At this temperature 
each specfes grows at about the same rate* 
D. — S. intermedia (above), and S. libertiana (below), showing the latter growing about twice as 
fast as S. intermedia at 20°
