The Sullivant Moss Society Harris was an active member of the Sullivant Moss Chapter, originally formed as a Moss Chapter of the Agassiz Association, and founded by
Abel Joel Grout and
Elizabeth Gertrude Knight Britton, and eventually renamed the Sullivant Moss Society. Harris contributed new plants to the Society from around Chilson Lake and helped to determine the classification of other members' submissions. She served as organizer and first head of the Society's Lichen Department from 1901 to 1905, and its Vice-President from 1904-1905. She donated many specimens to the Society's lichen
herbarium. The Sullivant Moss Chapter is now known as the
American Bryological and Lichenological Society.
The Bryologist Harris was the first to publish about lichens in
The Bryologist, a scientific journal devoted primarily to mosses, which was edited by Abel Joel Grout and
Annie Morrill Smith. Harris published a series of 12 papers on lichens (see Publications), which provided beginners with an overview of their
physiology and directions on how to identify and distinguish them from
mosses. With careful textual descriptions, illustrations, and photographs, Harris hoped to describe lichens well enough that they could be recognized with a simple hand lens. == Personal life ==
