Mary Cloyd Burnley Stifler (7 November 1876 – August 1956) was a 20th century botanist with a specialization in mycology. Early life and education Born in Williamsport, Pennsylvania in 1876 to Charles W. and Sallie H. (Updegraff) Burnley, Cloyd Burnley was raised in Willamsport along with her sister, Lucy Burnley. Cloyd Burnley's sister married Rev. James Madison Stifler, Jr, in 1900. Lucy died in 1903, leaving behind two children: James Madison Stifler III and Francis M. Stifler. Cloyd Burnley attended Williamsport Dickinson Seminary (now Lycoming College). She graduated from Goucher College in 1897. She continued as a graduate student at her alma mater before moving to Vassar College as an assistant. She completed her Master's degree in chemistry at the Women's College of Baltimore in 1899 while continuing to teach chemistry at Vassar. In 1908 she returned to Bryn Mawr as a research fellow and stayed until 1909. She co-authored two publications with fellow Bryn Mawr professor EP Kohler before he moved to Harvard University in 1910. While no record of Cloyd Burnley obtaining a doctorate exists, the State Microscopical Society of Illinois announced "Mrs. C.B. Stifler, Ph.D., will speak on little known "Flowerless Plants." Cloyd Burnley's work in mycology comes mostly from her time as a resident of Evanston, Illinois, when her husband held an appointment at the University of Chicago from 1931 to 1940, although a lack of records makes her position at the institution unclear. She served as the President of the Chicago Chapter of the Goucher College Alumnae Association. Career Though a chemist by training, Cloyd Burnley's interests and greatest impact were in the burgeoning field of mycology. Cloyd Burnley was the first to describe the Tuberaceae genus, a fungal genus containing truffles. In 1944, Cloyd Burnley gave a "rare and extensive collection" of fungal specimens to her alma mater, Goucher College. According to the Evening Sun, Cloyd Burnley's "special hobby is the collection, identification and study of the habits of representatives of fungi. In certain groups of the series Mrs. Stifler has become a recognized authority." Over 90 different fungal families were a part of the collection donated to the college. Her samples were intended for use in teaching students about mycorrhiza. Over 2,600 specimens attributed to Cloyd Burnley Stifler are housed at 13 different academic institutions. Her samples come from locations in Illinois as well as Florida, where she and her husband retired in
