 iua- the impression should not be conveyed that they differ from fungi 

 iu L^eneral. It is simply a conyenient way of treating of those lorins 

 that are especially injurious to cultiyated plants. The extent of the 

 annual injury done to agricultural interests by the attacks ot parasitic 

 funoi is little appreciated by the community at large. Eyen when it 

 is miderstood that the injury is caused by parasitic plants, so little is 

 known of their nature and conditions of growth that no very effectne
