Meinhard Michael Moser (13 March 1924 – 30 September 2002) was an Austrian mycologist. His work principally concerned the taxonomy, chemistry, and toxicity of the gilled mushrooms (Agaricales), especially those of the genus Cortinarius, and the ecology of ectomycorrhiza. His contributions to the Kleine Kryptogamenflora Mitteleuropas series of mycological guidebooks were well-regarded and widely used. In particular, his 1953 Blätter- und Bauchpilze (Agaricales und Gastromycetes) [The Gilled and Gasteroid Fungi (Agaricales and Gastromycetes)], which became known as simply "Moser", saw several editions in both the original German and in translation. Other important works included a 1960 monograph on the genus Phlegmacium (now considered part of Cortinarius) and a 1975 study of members of Cortinarius, Dermocybe, and Stephanopus in South America, co-authored with Egon Horak.
After showing interest in natural sciences in his youth, Moser studied at the University of Innsbruck. His university career began during World War II, however, and was soon interrupted by military service. He was stationed as a translator in eastern Europe, then captured and placed in a prisoner-of-war camp. He was released in 1948, subsequently returning to Innsbruck to complete his studies. After completing his doctorate in 1950, Moser worked in England for six months, researching the symbiotic relationships between plants and fungi. Upon his return to Austria, he joined the Federal Forestry Research Institute, where he remained until 1968, conducting influential research on the use of mycorrhizal fungi in reforestation. He began lecturing at the University of Innsbruck in 1956, and in 1972 became the inaugural head of the first Institute of Microbiology in Austria. He remained with the Institute until his retirement in 1991, while his scientific studies continued until his death in 2002. An influential mycologist who described around 500 new taxa, Moser received a number of awards throughout his life, and numerous fungal taxa have been named in his honour.
Moser was born on 13 March 1924 in Innsbruck, Austria, to Margaretha and Josef Moser. His father was a teacher at a technical college in the city, while his mother was the daughter of the botanist Emil Johann Lambert Heinricher. Moser attended primary school and grammar school in the city, and showed an interest in natural sciences from a young age. This was cultivated by Heinricher. Moser's earliest paintings of mushrooms date to 1935, when he was 11 years old.
In 1942, Moser enrolled at the University of Innsbruck, taking classes in botany, zoology, geology, physics, and chemistry. Austria was under the control of Nazi Germany at this time, and did not exist as an independent state. Moser became an "authorized mushroom controller and instructor", and was in turn directed to attend mycological seminars around Germany and Austria. At these seminars, he met a number of prominent mycologists, including Ernst Thirring, who introduced Moser to some of the scientific challenges surrounding the large genus Cortinarius. This issue remained an interest of Moser's for the rest of his life.
In 1943, aged 19 and after only three terms at Innsbruck, his studies were interrupted by military service. Having shown earlier promise in languages, he was trained as an interpreter, then sent to the Balkan Peninsula. He continued to have an active interest in mycology, collecting and identifying mushrooms and reading Rolf Singer's Das System der Agaricales.
In 1945, when Moser was 21 years old and still carrying out active military service, he was captured in Czechoslovakia by Soviet soldiers and made a prisoner of war. He was imprisoned in a labour camp in Crimea, in Ukraine. While a prisoner, he was involved in repairing the Institute of Biology of the Southern Seas, Sevastopol. His time at the camp was not easy; working in construction, he had to labour to his physical limits, and was involved in a serious crash that killed several other prisoners. Moser was released in 1948, and chose to return to his studies at the University of Innsbruck. His first publication came in 1949; "Über das Massenauftreten von Formen der Gattung Morchella auf Waldbrandflächen" ["Mass-fruiting of forms of the genus Morchella on forest-fire areas"] was published in the journal Sydowia. In 1950, under the supervision of Arthur Pisek, Moser completed his doctoral thesis, Zur Wasserökologie der höheren Pilze, mit besonderer Berücksichtigung von Waldbrandflächen [Water Relations in Higher Fungi with Special Emphasis on Forest-Fire Areas]. During his time at university, he became a member of both the Société mycologique de France and the British Mycological Society. Having become friends with prominent German mycologists during the War, he was keen to re-establish academic relationships throughout Europe in the years following the conflict's resolution.
Due to the quality of his doctoral work, Moser received a grant from the British Council and in 1951 moved to England, where he stayed for six months. While overseas, he performed research in the laboratory of Jack Harley in Oxford, looking into the symbiosis between fungi and forest trees, and spent some time performing taxonomic studies at the Royal Botanic Gardens, Kew. In 1952, after his return to Austria, he was offered a post at the Federal Institute for Forestry Research at Imst, which he accepted. There, he applied what he had learnt about the symbiosis of fungi and trees to the practical issue of reforestation in the Alps, and developed a method for the use of ectomycorrhizal fungi for the "inoculation" of trees, which later became standard practice around the world. Moser remained with the Federal Institute until 1968.
Moser continued his taxonomic studies while at the Federal Institute. In 1953, he published the first edition of Die Blätter und Bauchpilze (Agaricales und Gastromycetes) [The Gilled and Gasteroid Fungi (Agaricales and Gastromycetes)], a monographic treatment of the Agaricales and Gastromycetes of central Europe. The book listed 3150 taxa. It served as an update to Adalbert Ricken's 1918 Vademecum für Pilzfreunde [Handbook for Mushroom Hunters], though reflecting Moser's taxonomic views, which were highly influenced by Singer. The book was part of the series Kleine Kryptogamenflora Mitteleuropa [Small Cryptogams of Central Europe], edited by Helmut Gams. The work, which became known simply as "Moser", was updated and republished numerous times over the following decades, and translated into both Italian and English, with the latter being by the naturalist Roger Phillips. Some later versions of the book had a different focus. René Pomerleau described a 1967 edition, Röhrlinge und Blätterpilze [Gilled and Pored Mushrooms], containing descriptions of 2547 species, as "probably the most complete and up-to-date descriptive flora of this group of fungi for central Europe". Die Blätter und Bauchpilze (Agaricales und Gastromycetes) became important for the study of biodiversity in and out of Europe, with Singer calling the book a "much used and appreciated field manual". The work continued to be used as a standard reference for several decades; in 1981, it was still, in the words of the mycologist Richard P. Korf, "the most-used and most authoritative handbook on larger European fleshy fungi".
In 1956, while still a researcher at the Institute, Moser began lecturing on microbiology at the University of Innsbruck, with the title of "Privatdozent". He continued to publish while teaching. His monograph Die Gattung Phlegmacium (Schleimköpfe) [The Genus Phlegmacium (Slimeheads)] addressed Phlegmacium, at the time considered a genus but now considered part of Cortinarius, and was published in 1960 as part of the series Die Pilze Mitteleuropas [The Fungi of Central Europe]. Unlike the previous three books in the series, which were all written by German authors, the work addressed mushrooms that were of less interest to amateur mycologists; for instance, Phlegmacium was not considered to contain any significant edible species. The book drew upon Moser's expertise concerning mycorrhizal relationships. It listed 166 species, including some "exotic" taxa. Some of the listed species were described for the first time in that volume. The illustrations, which came in the form of a number of coloured plates, were mostly Moser's own work; Singer described these in a review of the book as "both in original execution and reproduction among the best that have been published". Discussing the book as a whole, Singer said that the volume, "outstanding for its good print, attractive appearance, and interesting contents, should be present in every mycological library".
In 1963, Moser published a second work in Kleine Kryptogamenflora Mitteleuropa, Ascomyceten (Schlauchpilze) [Ascomycota (Sac Fungi)]. This work was a monograph on the Ascomycota, focussing on the "Discomycetes". Though not as well known as his earlier book, it was well received in the mycological community. Korf, reviewing the work for Mycologia, said that "the book belongs on the shelf of every mycological library in Europe", praising the "[e]xcellent, workable keys to the orders, families, genera, and European species". Korf wrote that, "[i]f a single fault can be found, it is surely the lack of documentation provided". However, a combination of a lack of time and Moser's comparative lack of expertise in Ascomycetes prevented subsequent editions of the work.
Moser was promoted to Associate University Professor in 1964. Two years later, the Faculty of Science of the University of Innsbruck recommended that a chair of microbiology should be created at the Botanical Institute in Innsbruck. The Federal Ministry of Education accepted the recommendation. Moser was the only candidate for the position, and was unanimously named by a number of leading European botanists and mycologists for the post in 1967. The following year, Moser was promoted to full professor.
The president of the Austrian Mycological Society from 1970, Moser took up the position after the death of the previous post-holder, Kurt Lohwag, who had, in turn, taken it up after 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 a number of diploma theses.
1975 saw the publication of Cortinarius Fr. und nahe verwandte Gattungen in Südamerika [Cortinarius Fr. and Closely Related Genera in South America][note 1] Moser coauthored the work with 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. 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 Franz Schinner, C. 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 [Color Atlas of the Basidiomycytes] in 1985, presenting specimens of various Basidiomycota taxa. By the time of Moser's death, 19 volumes had been published; while some posthumously published volumes have listed Moser as an author.
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 from (or highly rare in) the 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 lectures.[note 2] This was held in Oslo, Norway from 11-17 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".
Over the course of his career, Moser collected more than 25000 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 ectomycorrhiza.
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 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 the complex genus Cortinarius. He published book-length works addressing Cortinarius taxa found in Europe and, co-writing with Horak, South America. Moser, working with Joe Ammirati, contributed to research on the genus in North America, and also examined Asian and Australasian taxa. He had a particular interest in Arctic–alpine habitats, and he documented, painted and published on his collections in these and other sites around the world. Moser initially doubted the usefulness of molecular phylogenetic analysis of the Agaricales, but later contributed to research in this area.
Cortinarius mushrooms are often highly colourful. Moser early progress towards studying the pigments in these mushrooms, hoping to find criteria for separating taxa, and some of his doctoral students studied these elements in depth. Cooperating with biochemists, he produced important work on the biosynthesis of pigments. Moser was also interested in the toxicity of the Agaricales, and, with his students, was involved with research on the toxin orellanine.
Moser's work on ectomycorrhiza, though perhaps unknown to many researchers familiar with his taxonomic work, was notable due to its focus on the fungal partners in the relationship. He engaged in a large amount of research on woodland in the transitional zone between subalpine and alpine habitats. His published results included the description of new taxa. In 1960, Singer referred to Moser as "one of the pioneers of mycorrhiza research, both basic and applied".
At the end of his life, Moser lived in the village of Vill, near Innsbruck. According to some of his colleagues, "Moser was rather shy, taciturn, formal and constrained in public or in official functions. In a relaxed atmosphere among students, collaborators or friends, he became extrovert and surprised many by his sense of humour and ready wit." He had a commitment to both mycological research and mycological education, and was fluent in several languages, such as – in addition to his native German – Russian and Swedish. He was known as an intellectual and a wide reader, with interests in fine art, classical music, literature, exploration, geography, and botany. In addition to reading and walking, he enjoyed stamp collecting and growing plants from seeds he had collected on his research trips. He was a capable cook, often creating mushroom-based dishes for guests, though was on one occasion poisoned during "gastronomic experiments" involving Phaeolepiota aurea (the golden bootleg) and Agaricus mushrooms. He was also known to make chanterelle schnapps, drinking it with his students and sharing his recipe with colleagues.
Throughout his life, Moser received a number of awards, including the Clusius Medal (Budapest, 1978) and the Kardinal Innitzer Preis (Vienna, 1985). In 1986, he was made a member of the Austrian Academy of Sciences. Having already been elected as an honorary member of the Ukrainian Botanical Society, he became a foreign member of the Ukrainian Academy of Sciences in 1992, the first mycologist to be elected. He was recognised by a number of mycological societies, including being made an honorary member of the Mycological Society of America in 1987, and Centenary Fellow of the British Mycological Society in 1996. He also received an honorary doctorate from the University of Lyon in 1984, and in 1990 was awarded honorary citizenship of Borgotaro, Italy.
