The National Fungus Collections of the United States is the "world's largest herbarium of dried fungus specimens". It is housed within the United States Department of Agriculture (USDA). The collection was established in 1869 from a core of fungus collections transferred from the Smithsonian Institution to the USDA. Frank Lamson-Scribner (1885-1891) and Franklin S. Earle (1891-1896) were the first two directors, followed by Flora Wambaugh Patterson in 1896. Patterson vastly increased the size of the collection from approximately 19,000 reference specimens to almost 115,000.

  • La collection mycologique nationale des États-Unis est « la plus grande collection du monde de spécimens de champignons secs. »Elle est administrée par le département américain de l'Agriculture, l'USDA. La collection a été créée en 1869 à partir de collections de champignons transférées de la Smithsonian Institution à l'USDA. Frank Lamson-Scribner (1885-1891) et Franklin Sumner Earle (1891-1896) ont été les deux premiers administrateurs de la collection, suivis par (en) en 1896. Cette dernière a considérablement augmenté la taille de la collection passant d'environ 19 000 spécimens de référence à près de 115 000. Durant son mandat, Flora Patterson, aidée de (en) et d'autres mycologues, identifièrent de nombreux champignons représentant une menace pour l'industrie agroalimentaire mettant en cause diverses maladies fongiques au nombre desquelles on trouve la (1909) causée par le mycoparasite , la galle verruqueuse causée par Synchytrium endobioticum, de même que celle causée par Cryphonectria parasitica. Ces maladies invasives et d'autres ont conduit à l'adoption de la loi sur la quarantaine des plantes de 1912. Vera Charles a également travaillé sur les agents pathogènes fongiques des insectes. D'autres scientifiques de l'USDA se sont signalés par leurs travaux en mycologie tels (en), engagée en 1912, qui est devenue une autorité concernant une famille de champignons responsables de l'anthracnose. (en), engagée en 1913, étudia le groupe des discomycètes et (en), engagé en 1917, a publié plusieurs études sur le genre Balansia qui provoque la stérilité chez les plantes herbacées. Succédant à Flora Patterson, (en) poursuivit le travail qui le conduisit à l'utilisation de (en) comme un organisme modèle pour la recherche génétique. (fr)

Patterson vastly increased the size of the collection from approximately 19,000 reference specimens to almost 115,000. Patterson and other mycologists at the collection during Patterson's tenure, including Vera K. Charles, identified numerous commercially threatening fungi, including the (1909), the potato wart disease (Synchytrium endobioticum), and chestnut blight. These and other invasive diseases led to the passage of the Plant Quarantine Act of 1912. These scientists were part of a wave of government-funded research into agriculture and disease. Vera Charles also worked on fungal pathogens of insects. The National Fungus Collection also hired a number of other scientists all of whom did significant work on economically important crops. These included Anna E. Jenkins, hired in 1912, who became the "foremost authority" on . Edith K. Cash, hired in 1913, investigated discomycetes (cup fungi) and William W. Diehl (hired in 1917) wrote extensively on Balansia which causes sterility in grass plants. After Patterson's retirement, James R. Weir ran the collection for four years; his work at the collection ultimately led to use of Neurospora as a model organism for genetic research. (en)
