Charles Horton Peck was the New York State Botanist from 1867 to 1915. Presented here are taxa from the United States that were described by Peck (along with other authors in some cases). Numerous taxa on this list represent macrofungi, many described from New York State; however, over one thousand are species of microfungi. Peck described several slime mold species that also appear on this list. For clarity, the type of organism is listed in the notes.
