Fungi. 



Phytophthora infestans.* — L. Matruchot and M. Molliard have 

 made a series of cultures of this fungus. They found that on a slice 

 of living potato it grew freely, also on cucumber and Spanish melon. 

 On the two latter it grew after they had been cooked, but not on the 

 potato. Probably the starch of the potato had swelled to an extent 

 that prevented the mycelium from penetrating the tissues. Spores 

 were produced normally only on living material, and in no case were 

 ©ogonia or chlamydospores formed. The writers conclude that the 

 fungus persists by means of the mycelium. They find also that the
