Rolf Singer

Rolf Singer (1906 - 1994) was a German-born mycologist and one of the most important taxonomists of gilled mushrooms (agarics) in the 20th century. He wrote major books like "The Agaricales[?] in Modern Taxonomy". He fled to various countries during the Nazi period, pursuing mycology in far-flung places like the Soviet Union, Argentina, and finally the United States, as mycologist at the Field Museum[?] in Chicago.
