the death of Thirring earlier that year. Moser remained the society's president for 21 years. In 1972, he became the head of the newly established Institute of Microbiology at Innsbruck, the first of its kind in Austria. He remained in charge of the Institute until his retirement. He taught on a wide range of subjects, including the taxonomy of fungi, ecology of fungi, mycogeography, bacteriology, virology, chemotaxonomy, molecular genetics, microbial toxicology, immunology, and symbiosis. During his career at the university, he supervised over 60 doctoral theses, in addition to diploma theses. Cortinarius Fr. und nahe verwandte Gattungen in Südamerika [Cortinarius Fr. and Closely Related Genera in South America] was published in 1975. Moser coauthored the work with the mycologist Egon Horak, and it was dedicated to Singer. It was a study of South American Cortinarius, Stephanopus – a genus described in this work for the first time – and Dermocybe taxa, containing descriptions of 276 new species. Along with his earlier monograph on "Phlegmacium", it proved to be some of Moser's most important work, serving to encourage other mycologists to work on Cortinarius. The mycologist Alexander H. Smith stressed the significance of the work, saying "Anyone who has not worked in the systematics of Cortinarius cannot fully appreciate the magnitude and importance of this work to the general subject of the distribution and speciation of the higher fungi." In 1983, in recognition of his forthcoming 60th birthday, an article dedicated to Moser was published in Sydowia. The piece, compiled by the microbiologist Franz Schinner, the mycologist Cuno Furrer-Ziogas, and Horak, contained a detailed biography of Moser and a full bibliography of the 116 research publications he had authored or co-authored between 1949 and 1983. Writing with Walter Jülich, Moser published the first volume of the book series Farbatlas der Basidiomyzeten [Colour Atlas of the Basidiomycytes] in 1985, presenting specimens of various Basidiomycota taxa. By the time of Moser's death, 19 volumes had been published; some posthumously published volumes have also listed Moser as an author. Retirement and death In 1991, Moser retired from his teaching position to avoid the administrative burden and to focus on his research into Cortinarius and related genera. After his retirement, he continued to work heavily, typically beginning at 5 am. In 1992, he researched the presence of Agaricales in the Crimean Mountains, identifying approximately 70 species that were not documented (or highly rare) in the
