 side of the road between Dalmally and Cladich, near Loch 

 Awe. It produces dull orange warts about 1 mm. high and 

 broad, which may be scattered, or may be united into crusts. 

 The older warts become brown. The development was 

 not followed out by me ; but it is described as follows 

 The swarmspore, after penetrating the epiderm, develops 

 into a thin-walled round cell, from the upper part of which 

 a second similar cell grows out, and receives the cell-con- 

 tents ; the sporangia are formed in this latter cell, the other 

 remaining empty. The swarmspores, when fully devel- 

 oped, burrow into the cells in immediate contact with the 

 group of sporangia, or enter singly or a few together into 

 the epiderm-cells of the host plant, and there form spherical
