region, including some new to science. In 1995 a Festschrift was published in Moser's honour as a supplementary volume of Sydowia. It contained an article on Moser himself, and 16 mycological articles dedicated to him for his 70th birthday. Moser died on 30 September 2002. He was present at the International Mycological Association's 7th International Mycological Congress, at which he was listed as an author or co-author for four separate presentations. This was held in Oslo, Norway, from 11 to 17 August. After returning home, he suffered a series of heart attacks. He was admitted to hospital, but his condition rapidly declined, resulting in his death. Obituaries were published in a variety of academic journals, including Mycological Progress, Mycological Research, Sydowia, Österreichische Zeitschrift für Pilzkunde, and Berichte des Naturwissenschaftlichen-medizinischen Verein Innsbruck. Horak and colleagues wrote in one that Moser's death meant "an irreplaceable loss to the international community of mycological science", and, in another, that the "mycological world has lost one of its pillars of taxonomy for agarics and boletes. His former students, assistants and collaborators at the Microbiological Institute at the University of Innsbruck, his professional colleagues in the mycological community worldwide and his many friends will deeply regret the loss of a distinguished researcher, teacher, leader and mentor." In a short obituary as part of their report on the Eighth International Symposium on Arctic-Alpine Mycology, the mycologists Cathy Cripps and Joe Ammirati called Moser a "gentlemanly scholar" who "led us in his quiet way across the tundra and down many dichotomous paths". Research Over the course of his career, Moser collected more than 25,000 mycological specimens. He first described around 420 Cortinarius species and around 80 other species, including both agarics and boletes. He circumscribed three new genera: Singeromyces (1966), Stephanopus (1975), and Anamika (2002). Much of his research concerned the Agaricales – including the classical morphotaxonomy and the chemotaxonomy of the order, as well as the toxicity of the chemical constituents of the order's members – though a further key research concern was the ecology of ectomycorrhizal symbiosis. In the early decades of his career, Moser sought to clarify the taxonomic identity of European fungi by collecting specimens to be described as neotypes in the localities studied by the mycologist Elias Magnus Fries, but this was no longer necessary after changes to nomenclatural rules that took effect in 1981. Among the Agaricales, Moser's interest was primarily in
