The aecidiospores—Boestelia cornuta—occur on species of Pyrus {Sorbiis); they are much smaller than those of Roestelia penicillata. The Hoestelia themselves are long, curved, and hom-like, while the walls of the peridial cells are beset with short processes (Fig. 224). Where Pynts Aucuparia occurs mixed with Pyrus Malus, it has been observed that Boestelia cornuta is conf

Other Diseases Chlorosis (Nonparasitic)—A yellowing or chlorosis of young flax plants is common in many areas in Manitoba and Saskatchewan. Sometimes this condition is due to lack of aeration in water-logged soil. The lack of aeration results in a temporary nitrogen deficiency in the soil. When chlorosis occurs in the higher parts of fields, as well as in the low, wet spots, it may be a sign of iron deficiency. This deficiency is induced by an excess of lime in the soil, which makes the iron una

Under diverse conditions the fungus must be constantly andabundantly associated with the disease, or pathological state. b. The organism should be grown in pure cultures, when pos-sible, and its differential characteristics well studied. 76 ARTIFICIAL INFECTION 11 c. The characteristic disease should be produced by infectionexperiments with a pure culture. d. The fungus associated with the disease induced should beidentified as the one originally separated, and any
