I. INTRODUCTION 



For upwards of twenty years the writer has been paying such 

 attention to the assembling and investigation of various parasitic 

 Florideae as has been possible from his opportunities and leisure for 

 such work. The work was started on the coast of New England and 

 continued on the western coasts of North America. He has received 

 great help from students and friends, due acknowledgment of which 

 will be made in the proper places. It is hoped that the present paper 

 will be the first of a series dealing with the various materials brought 

 together at the University of California and the results of their 

 investigation.
