The Phycological Society of America was established in 1946 by and for phycologists, or those who study algae. The records consist of presidents' files and correspondence, financial ledgers, membership lists, conference programs, meeting minutes, videotapes, and a complete run (1965-1990) of the Journal of Phycology. The collection includes notebooks (1874-1883) with sketches of algae by botanist Francis Wolle (1817-1893).
