The spores divide at maturity trans- versely into four cells, only the two end cells of which germinate, doubt- less at the expense of the contents of the remaining two. The germ- tubes penetrate the epiderm of the leaf of the host, and a new mycele is formed which again bears basids. If, however, germination takes place elsewhere than on the proper host-plant, and conditions for the vegeta- tion of the fungus be otherwise f
