Fungi. 



Plasmopara cubensis in Austria.* — Ludwig Hecke records the 

 appearance of this dangerous parasite of cucumber. It has long been 

 known in America, but not yet recorded for Austria or Germany. The 

 leaves are attacked and very soon wither and fall, so that the health of 

 the plant and the development of the fruit are seriously affected. He 

 describes the fungus in detail, and gives an account of the methods 

 employed for its eradication.
