The spore-cells or the honey-dew spores may be carried to another flower and thus the life-story is recommenced by the new infection of the grain. The ergot fungus is common on a great many grasses and particularly upon cultivated species as wheat, rye, barley, etc. It is found very abundantly upon wild rice in many places and is also abundant on grasses growing on railroad right-of-ways.

A very close rela- tive of the ergot fungus is the caterpillar fungus, the habits of which have already been described in a previous chapter. Spores of the fungus send out germ threads which penetrate the hard coat of the caterpillar or grub and, feeding on the soft.
