The passing of Clark Thomas Rogerson on September 7, 2001, at age 82, marks the loss to Mycology of one of the last of the classical mycologists; he was a scientist whose love of fungi knew no bounds. Rogerson's life was devoted to mycology. His correspondence and contacts were global. His influence on the Mycological Society of America and this publication, Mycologia, was immense. He was born on October 2, 1918, in Ogden, Utah, where he died.

From 1942 to 1945, Rogerson was a technical sergeant in laboratory and pharmacy in an Army evacuation hospital in the Solomon and Philippine islands. He spoke infrequently of his wartime experiences and was impatient with those who did so, but he did recall how he traded his ration of beer and cigarettes for leave. He was in the first medical unit to care for internees released in the Philippines near the end of the war and was the first mycologist to visit Los Baños Agricultural Research Station near Manila after the war.

Rogerson's first appreciation of fungi as organisms rather than as plant pathogens came in the Solomon Islands. Service personnel were encouraged to communicate with U.S.-based academics. B.L. Richards, Rogerson's undergraduate advisor at Utah State, had spent a year's sabbatical at Cornell University, so perhaps it was natural that Rogerson corresponded with Harry Fitzpatrick and, through Fitzpatrick, with George Cummins, Robert Hagelstein, Fred Seaver and Josiah Lowe. Throughout the war he collected myxomycetes, fungi, plants and butterflies and sent them to Cornell or to the Smithsonian Institution. He recalled hitch hiking 50 miles from his camp to Los Baños in an unsuccessful attempt to find a Corynelia on a Podocarpus that supposedly was found on Mount Maquiling. All of his collections arrived unlabelled as to geographic origin except for a vague citation of "Pacific Region" but were provided with full collecting details after the war.

Rogerson's wartime interest in fungal taxonomy and experience in tropical mycology had developed to such an extent that he decided to continue study in fungal systematics. The G.I. Bill of Rights gave him a choice of pursuing a doctorate with Lee Bonar at the University of California at Berkeley or of going to Cornell to work with Fitzpatrick. He chose Cornell, he said, because he had never traveled east of Colorado and, of course, another reason was the wartime contact that he had established with Fitzpatrick.

He was a teaching assistant with Prof. Fitzpatrick from 1946 to 1950. Fitzpatrick suggested that Rogerson study the Hypocreales, which remained Rogerson's first love throughout his career. Although Fitzpatrick did not undertake cultural studies of his own group, the Coryneliales, Rogerson documented through cultural studies connections between Hypomyces species and their anamorphs—or imperfect states as they were known at the time. Rogerson's work with Hypomyces and its anamorphs was ground-breaking because studies of ascomycetes that also included the anamorphs were not common, despite the elegant 19th century publications of Brefeld and van Tavel and the Tulasne brothers. While at Cornell, Rogerson published his first scientific paper, "The vegetation of the Bergen Swamp VI. The fungi" (Rogerson and Muenscher 1950). There are not many lists of fungi from any area that are as complete as this one.

Although Fitzpatrick was not an experienced field mycologist, he encouraged Rogerson and fellow student Richard P. Korf to collect. Fitzpatrick and his wife would drive the students into the field, drop them off and pick them up later with their finds. Rogerson recalled how his fastidious advisor made sure that his students didn't dirty his immaculate car.

Fitzpatrick's fastidiousness and hypochondria were locally famous and his repartee with H.W. Whetzel on alcohol and smoking, in which Whetzel apparently indulged, was constant and sarcastic. However, few were prepared for Fitzpatrick's suicide in 1950. Rogerson took up the courses that Fitzpatrick had been teaching and Donald S. Welch stepped in to serve as major advisor for Rogerson and Korf during the final months of their studies.

Cornell mycologists trace their heritage to the German mycologist Anton deBary. William R. Dudley, the first cryptogamic botanist at Cornell, studied with deBary in 1887, and from 1888 to 1892 was a staff member of the Cornell Experiment Station, where he published on plant diseases. Both J.C. Arthur and G.F. Atkinson were students of his, as was Mason B. Thomas. Thomas went to Wabash College, in Indiana, where he trained a number of notable 20th century mycologists, including Cornellians H.H. Whetzel and H.M. Fitzpatrick. Thus, Rogerson's mycological lineage to deBary was completed when he received his doctorate in 1950 with a major in mycology and minors in taxonomic botany and genetics. His thesis was a monograph of the fungicolous ascomycete genus Hypomyces.

In 1950, Rogerson joined the faculty of Kansas State University as an assistant professor, ultimately becoming asssociate professor of botany and mycologist of the Kansas Agricultural Experiment Station. While at Kansas, he collaborated with agronomists and plant pathologists in fungus identification. Between 1952 and 1967, he published nearly 20 papers on fungal novelties, aeromycology and fungal-induced plant diseases in Kansas, alone or with collaborators, including, C.L. Kramer, E.S. Luttrell, S.M. Pady, R. Sprague and his master's student R.L. Shaffer. Rogerson remained at Kansas State until 1958, when he was recruited by W.J. Robbins, director of The New York Botanical Garden, to fill the vacancy left by the departure of D.P. Rogers for the University of Illinois.

Rogerson, the new curator of cryptogamic botany, arrived at the New York Botanical Garden at the same time as the bryologist and new director, William C. Steere. It was an exciting time for mycology at the Garden. Among Rogerson's mycological colleagues in the Harding Laboratory were B.O. Dodge, in his last professional years, Alma Whiffen Barksdale and Rogerson's former student Susan Carey Canham. Alma Barksdale was discovering and characterizing the sex hormones of Achlya (and one of us—G.J.S.—produced hormone A as pregraduate, summer employment). William J. Robbins, who became a professor at Rockfeller University after he retired, and Annette Hervey were trying to induce morels to sporulate in pure culture. They also were trying to get the "ant fungi" to produce basidiomata in culture. Marjorie Anchel, Trevor McMorris and Susan Carey were finding novel secondary metabolites and antibiotics in basidiomycetes and ascomycetes. David Davis was working on pathogenicity of the fusaria. P.P. Pirone, the Garden's plant pathologist, was writing his books about urban plant pathology and consulting with the Rockefeller family about their plantings. Rogerson collaborated very closely with Anchel, Carey and Whiffin by identifying the fungi that produced the secondary metabolites. Robbins and Hervey were working closely with Neal Webber of Swarthmore College in his early study of Attine ants and the fungi that they culture. Rogerson's part in that study was to characterize the "ant fungi", as Webber's extensive collection was known. Also present in New York City during the 1960s was Lindsay S. Olive, a professor in the Biology Department of Columbia University. Rogerson was an informal advisor to Ronald H. Petersen, a doctoral student of Olive's, in his study of aquatic hyphomycetes. Another frequent visitor to the Harding Lab was George N. Bistis, known for his work on Ascobolus genetics and an associate of Olive's at Columbia and later at Drew University. The professional mycological scene in New York City has changed dramatically in the past 30 years, to the extent that today there is only one full-time mycologist at the Garden and none elsewhere in the city.

Throughout the 1960s and most of the 1970s Rogerson was the only mycologist in the New York City area who authoritatively could identify mushrooms for the growing numbers of interested amateurs. He responded to scores of mushroom-poisoning calls from anxious parents and hospital emergency rooms. He assisted in the formation of the three major amateur mushroom groups in the New York City area, viz. the New York Mycological Association, the New Jersey Mycological Association and the Connecticut-Westchester Mycological Association (COMA). He developed a good working relationship with Gary Lincoff as Lincoff prepared his guide to the mushrooms of North America. Rogerson worked in the Harding Lab every weekend and was available to representatives of clubs, such as COMA, to review their foray collections. He took each request for identification seriously and carefully explained to the amateurs the name of the fungus and its possible synonymy. He valued his relationship with amateur mycology, and in return amateur mycologists provided him with many specimens of fungicolous Hypomyces.

As curator of cryptogamic botany, Rogerson was directly responsible for all accessions and loans of ferns and mosses, as well as of fungi and lichens, until about 1965 when, first a bryologist and later a pteridologist were added to the cryptogamic staff. A second mycologist, Kent P. Dumont, was hired in 1971. Soon after Rogerson's arrival at the Garden, he was approached by the director of science, Bassett Maguire, about reinitiating the Memoirs series there. In return, Rogerson was relieved of the constant need to obtain grants in exchange for taking on the role of editor of the Garden's publications, including Memoirs (1969–1988), Flora Neotropica (1969–1984) and North American Flora (1963–1997). In addition to these editorial tasks, Rogerson was the compiler of the Index to American Botanical Literature for the Torrey Botanical Club (1961–1984), editor of the Taxonomic Index for the American Society of Plant Taxonomists (published as Brittonia, 1961–1967) and member of the editorial board, 1967–1997, of Abstracts of Mycology.

Rogerson was an adjunct professor of biology at Columbia University and at the Herbert H. Lehman College of the City University of New York. He taught mycology at the Garden and had one master's student at Kansas State (R.L. Shaffer, M.A.) and doctoral students at both Columbia (Susan Carey Canham Travers, Anna F. Doyle, Gary J. Samuels) and Lehman (Rosalind Lowen).

Rogerson's life was mycology, and his friends were mycologists. He spoke about how, as a student in the late 40s, he received an impromptu mycological lecture by C.L. Shear as the two sat side-by-side on a log during a national foray in Great Smoky Mountains National Park. He met the Austrian mycologist Franz Petrak in the early 50s at Beltsville, Maryland; Petrak did not speak English, but John Stevenson translated. Rogerson worked almost every day of the year. When one of us (G.J.S.) first started his studies with Rogerson, he quickly learned that it was impossible to arrive at the laboratory ahead of his mentor. Rogerson's life could have been described as simple: It revolved around the fungi-collecting season. In his early years in New York City, Rogerson lived on Central Park West, making the hour-or-more subway commute twice each day. He enjoyed New York for ballet, exotic food and the cinema (chiefly Westerns at the Thalia at 92nd St.). But, gradually he dropped his subscriptions to ballet and became intolerant of any but bland food. In his later years, he lived in a simple two-room apartment in the Bronx, an easy walk to the Garden and the Garden Café (known to many visiting mycologists), where he took breakfast and lunch most days.

He traveled to his home in Utah each spring and didn't return until early autumn. These annual summer trips enabled him to reconnect with his family and to care for his mother's roses. In Utah he attempted to collect a specimen of every fungus that ever had germinated in the state. Rogerson made lists of all of the fungi that he collected in Utah, and those specimens are deposited in the Garden's herbarium. An effort to bring Rogerson's Utah fungi into interactive form is being made now at BPI. In later years, he joined one of us (R.F.) in expanding his collecting to Nevada.

Rogerson never owned or drove a car, and he never flew because of his experience with two air crashes during the war. He traveled by bus until a bus driver's strike in the late 1960s persuaded him to travel by rail. He loved fieldwork and was a natural teacher. He would drop whatever he was doing on a moment's notice to spend weeks in the field. Family and friends took him collecting in New York state, the Highlands Biological Station in North Carolina, and in Utah, the West and elsewhere. In the field, he was eager to get going before daylight and documented collections until 10 p.m. Each day in the field with him was educational because he would name flowering plants as well as the fungi. Rogerson collected fungi everywhere he went. At MSA meetings, he looked for plant diseases on college campuses before breakfast and a long day of sessions. He frequently made day trips from New York, especially with his close friend Stanley J. Smith, the New York state botanist throughout the 1960s. Any mycologist visiting the Garden was encouraged to join Rogerson in a lunchtime ramble through the forested section, and any fungi encountered were fair game. One new species of Physalacria on Cryptomeria (Bertier and Rogerson 1981) and one new Fusarium on Staphylea (Samuels and Rogerson 1984) were found on such walks.

Rogerson's research specialties were, in order of importance to him: taxonomy of Ascomycetes, particularly the Hypocreales, taxonomy of fungicolous fungi, the fungi of New York and Utah. He wrote 65 original research publications in addition to bibliographic publications (e.g., Barr et al 1986, An annotated catalog of the Pyrenomycetes described by Charles H. Peck and Barr et al 1996, The fungi described by Ellis). The fungi described by Fred J. Seaver, an unpublished list, is held in the NYBG archives.

Rogerson was a deeply involved member of the Mycological Society of America. He held the job of managing editor of Mycologia for 30 years, after the tenures of F.J. Seaver and D.P. Rogers. He was simultaneously managing editor and editor-in-chief, 1960–1965, and successively vice-president, president elect and president of the Mycological Society of America. He was secretary-treasurer of the society, 1973–1974, when Alma Barksdale was too ill to complete her term (and at a time when one person was expected to do what two do today). His 1969 "Presidential Address" was never actually delivered in person, much to his relief, because the annual MSA meeting that year was deferred to the International Botanical Congress in Seattle. However, he prepared a review and key to the hypocrealean fungi, which was published in Mycologia (Rogerson 1970). He never touched a computer, but he personally prepared the year-end index to Mycologia for many years and oversaw the preparation of the 58-volume index to the journal; that work included the preparation of several volume indexes himself. He was historian of the Society for most of his years at the Garden. Rogerson was a strong supporter of student development. He was one of the most generous donors to MSA student travel awards, and he administered the Gertrude S. Burlingham award of the New York Botanical Garden, which enabled many young mycologists to visit the Garden and work with the collections.

In August 1981, the Mycological Society of America recognized Rogerson's years of service to the Society and Mycologia with a special award. The North American Mycological Association recognized his many contributions to amateur mycology in 1980, and he was the recipient of the Distinguished Service Award of the New York Botanical Garden in 1984. The cumulative Mycologia index Vols. 59–80 was dedicated to him. COMA named its annual field trip the Clark T. Rogerson Foray. A Festschrift for the 70th birthday of Clark T. Rogerson was published in 1989 (Samuels GJ (ed.) Mem. New York Botanical Garden 49:1–374. This included original research publications, appreciations from colleagues and a biography with photographs). The Clark T. Rogerson student research and travel award has been established by the Mycological Society of America and will begin recognizing student excellence in 2004.

Eponymy includes the flowering plant genus Rogersonanthus B. Maguire & B.M. Boom, the fungal genus Rogersonia Samuels & Lodge, and the fungal species Clonostachys rogersoniana Schroers, Zelleromyces rogersonii Fogel & States and Pseudocercospora rogersoniana U. Braun & Crous.

The biggest impact of Rogerson's professional life was probably his influence on others. We already have noted his close involvement with North American amateur mycology. He followed the mycological literature closely and provided collections to specialists, and some of these have been described as new taxa. He added many thousands of records of fungi, mainly from Utah, to the Garden herbarium. These collections may represent the most extensive collecting from one geopolitical region and are available for study by systematists and others interested in biological diversity. Finally, his direct impact on his students has been incalculable. His 1970 key to the hypocrealean fungi resulted from an exhaustive literature survey that lead to the publication of keys to, and redescriptions and redefinitions of the genera of the Hypocreales (Rossman et al 1999). Publishing by one of us (G.J.S.) and his students is facilitated daily by the free access granted by Rogerson to his now more than 50-year-old files on all taxa of the Hypocreales. Those often crumbling pages of yellow paper with hand copied descriptions taken from the likes of Berkeley and Hennings are an invaluable resource to this author, his collaborators and to the next generation of specialists in hypocrealean fungi.

Rogerson was a gentleman, open and warm-hearted. He worked at a time when he could afford not to specialize in any single, arcane aspect of mycology, and in a professional situation where he could follow his curiosity and passion without the need to justify his activities through the process of grant submission. He followed his passion, which he shared with everybody who knew him.
