Many fungi of this class produce their winter spores on fallen leaves or twigs, for instance the black blotch fungus of maple leaves. It is probable that this currant fungus has some winter form on the dead vegetable matter about the bushes. Hence the remedy should be sought in burning the leaves that fall and any other rubbish that might harbor the fungus. A similar species Septoria rubi, West, is very common on blackber- ries all over the country. It produces roundish spots with a red or purple margin and a brow
