Rolf Singer (June 23, 1906 – January 18, 1994) was a German mycologist and taxonomist of gilled mushrooms (agarics).
He wrote the book "The Agaricales in Modern Taxonomy". He fled to various countries during the Nazi period, pursuing mycology in the Soviet Union, Argentina, and finally the United States, as mycologist at the Field Museum in Chicago.
After receiving his Ph.D. at the University of Vienna in 1931 he worked in Munich. By 1933, however, Singer left Germany for Vienna due to the political deterioration in Germany.[1] There he met his wife, Martha Singer. From Vienna, Singer and his wife went to Barcelona, Spain, where Singer was appointed assistant professor at the Autonomous University of Barcelona. Persecution by the Spanish authorities on behalf of the German government forced Singer to leave Spain for France in 1934. After a fellowship at the Museum d'Histoire Naturelle in Paris, Singer again moved, this time to Leningrad, where he was senior scientific expert at the Botanical Garden of the Academy of Sciences of the USSR. During his time at the academy, Singer made many expeditions to Siberia, the Altai Mountains, and Karelia. In 1941, Singer emigrated to the United States. He was offered a position at Harvard University's Farlow Herbarium as a research associate, then as Assistant Curator, then as acting Curator following the death of Dr. David Linder. He spent a total of seven years at the Farlow. During this time, Singer also received a Guggenheim Fellowship for studies in Florida, and taught at the Mountain Lake Biological Station of the University of Virginia.
In 1948, Singer left Harvard to become professor at the Universidad Nacional de Tucuman in Argentina. Later, in 1961, Singer became professor at the Universidad de Buenos Aires. During his time in South America, Singer, his wife, and his daughter Heidi collected extensively. Singer's last faculty appointment was at the University of Illinois at Chicago, from 1968 to 1977.
Singer was an author (or co-author) of new fungal species, having formally described 2260 in his career.[2] He was also a prolific writer, with more than 400 publications to his name.
He has been honoured in the naming of several taxa of fungi.[3] Including; Singeriella Petr. in 1959 (in Vizellaceae family),[4] Singera Bat. & J.L.Bezerra 1960 (Vermiculariopsiellaceae family),[5] Mesosingeria S.Archang. 1963 (Fossil, order Cycadales),[6] Singeromyces M.M.Mosera, 1966 (in the family Boletaceae),[7] Singerina Sathe & S.D.Deshp. 1981 (in the family Agaricaceae),[8] and lastly, Singerocomus T.W.Henkel & M.E.Sm. 2016 (Boletaceae family).[9]

Conocybula cyanopus is a species of fungus that contains psychoactive indole alkaloids including psilocybin and the uncommon aeruginascin. Originally described as Galerula cyanopus by American mycologist George Francis Atkinson in 1918. It was transferred to Conocybe by Robert Kühner in 1935 before being transferred to Pholiotina by Rolf Singer in 1950 and finally to Conocybula by T. Bau & H. B. Song in 2024. Conocybula cyanopus is recognized as the type species of Conocybula sect. Cyanopodae. While the taxon Conocybula smithii has sometimes been considered as a junior synonym of Conocybula cyanopus, this much more common species differs by distribution, DNA barcode, and the length of cheilocystidia and pileocystidia.
Gymnopilus dilepis is a species of mushroom in the family Hymenogastraceae. This species is found in India, Malaysia, North America. It was given its current name by mycologist Rolf Singer in 1951. It contains psilocybin and related hallucinogenic substances.
Paragyrodon is a genus of fungi in the family Paxillaceae. It is a monotypic genus, containing the single species Paragyrodon sphaerosporus. Paragyrodon was circumscribed by Rolf Singer in 1942.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
