Word Document version

Working list of 856 identified species and varieties. Some names on this list are tentative and not yet confirmed. This list is primarily macrofungi - those visible by eye, but does not include lichens, rusts, smuts, or slime molds. There are closer to 900 species of macrofungi found in Cook County because this list does not include the many collections that are not identified to species, particularly groups such as Cortinarius, Russula, crust fungi, and small ascomycetes.

Cook County is shown in red

This list includes Field Museum Herbarium records (1890's to present, some names not taxonomically updated) and current research collections (1994 to present). A majority of records come from our work at Swallow Cliff Woods and Cap Sauers Holdings in the Palos area, plus Green Lake Savanna and Powderhorn Prairie. Additional collections are from forays of the Illinois Mycological Association to Forest Preserves of Cook County, especially Busse Woods, Deer Grove Woods, and Harm's Woods. The 2002 Calumet Bioblitz added 6 species to this list. The Museum Campus, other green spaces, and urban areas are also represented on this list. For further information on herbarium collections see Fungi Collections at The Field Museum.

These fungi and more will be soon be found at the vPlants - online herbarium.

Taxon names are listed by Phylum then by morphological group.
