Viktor Litschauer (1879 – 27 December 1939 in Innsbruck) was an Austrian mycologist.
From 1899 to 1903 he studied at the Vienna University of Technology, where he was a pupil and assistant to Franz Xaver Rudolf von Höhnel. For several years he served as a lecturer at the Vienna Gewerbemuseum, then from 1908 to 1936 he was a professor of natural history at the Innsbruck Handelsakademie (academy of commerce).[1][2] From 1931 to 1933 he edited the exsiccata Fungi selecti exsiccati Europaei with Heinrich Lohwag.[3] Two further exsiccata-like series were issued by him later.[4]
The mycological genera Litschauerella (Oberw., 1966) and Litschaueria (Petr., 1923) commemorate his name.[1]
