Franz Petrak (9 October 1886, Mährisch-Weißkirchen – 9 October 1973, Vienna) was an Austrian-Czech mycologist. From 1906 to 1910, he studied botany at the University of Vienna, where he was a student of Richard Wettstein. In 1913 he obtained his doctorate of sciences, and until 1916, worked as a high school teacher in Vienna. During World War I, he was stationed in Galicia and Albania, where he collected specimens in his spare time. From 1918 to 1938, he worked as a private scientist in his home town, and from 1938 to 1951, was associated with the Naturhistorisches Museum in Vienna. He was the author of nearly 500 published works, primarily in the field of mycology. Much of his mycological work was published in the journal ''Annales mycologici'' and its successor ''Sydowia''. Reportedly, his private herbarium contained 100,000 specimens.〔 As a taxonomist, he described numerous species within the genus ''Cirsium'' (family Asteraceae). The mycological genera ''Petrakiella'', ''Petrakiopeltis'' and ''Petrakina'' are named in his honor, the latter genus being circumscribed by Raffaele Ciferri in 1932.〔 Franz Petrak died 9 October 1973 in Vienna. == Selected works == * ''Die nordamerikanischen Arten der Gattung Cirsium'', 1917. * ''Die Gattungen der Pyrenomyzeten, Sphaeropsideen und Melanconiee'', 1926. * ''Die phaeosporen Shaeropsideen und die Gattung Macrophoma'', 1926. * "Index of fungi.
