In French Guiana on a 1986 expedition sponsored by the Biological Diversity of the Guiana Shield Program, Rossman met the French botanist Christian P. Feuillet.[10] They married in King County, Washington, on 4 September 1988. They have a daughter.[2]
In 1996 Rossman told the science journalist Carol Kaesuk Yoon that for some types of organisms, such as microfungi, New York state's forests are almost as unexplored as the tropical forests.[11] Rossman, with coauthor David L. Hawksworth, suggested that about 1.4 million fungal species were undescribed as of 1997.[12]
In 2009 Rossman became the research leader of the Systematic Mycology and Microbiology Laboratory (SMML) in Beltsville, Maryland. She has also been director and curator of the U.S. National Fungus Collections (BPI — USDA Bureau of Plant Industry), which are located at the SMML. The SMML and the U.S. National Fungus Collections are part of the USDA's Agricultural Research Service. She led research on Hypocreales (particularly Calonectria, Nectria and Ophionectria), Diaporthales and other microfungi that cause plant diseases. She made important collections, not only with her husband, but also with Laurence Skog and Gary Joseph Samuels.[13] Together with David F. Farr, she manages a database containing information about the fungal specimens in the U.S. National Fungus Collections. They also maintain a database with data on fungi that have plants as hosts. She has contributed extensively to the Index Fungorum.[14]
