 branches acute, spores very 

 minute, globular." 



The general appearance of 

 the fungus, as seen growing 

 upon a panicle of sheep's 

 fescue, Festuca ovina, L., is 

 shown twice the natural size 

 at Fig. 17. The fungus tufts

 ous, pinkish base of spawn or 

 mycelium, which has a tend- 

 ency to glue different parts of 

 the grass together as shown 

 at Fig. 18, where three grass 

 stems invaded by the fungus 

 are illustrated five times the 

 natural size. The tufts grow 

 on the stems, leaves, and every 

 other part of the grasses 

 affected, and the growths show

 ground. There can be little

 fungus tufts to the ground is 

 one of the means by which 

 the propagation of the pest is
