Canadian mycologist (1903-1993).
Mildred Katherine Nobles (7 June 1903 – 26 March 1993) was a Canadian mycologist. Born in Colborne, Northumberland County, Ontario, the only surviving child of William Harold and Ethel Nobles, she spent her early life at the family farm in Vernonville. She was an authority of the culture and identification of wood-rotting fungi, and developed a numerical identification system today known as the "Nobles Species Code". Nobles died in Ottawa, Ontario after a short illness. She was awarded the "Distinguished Mycologist" award, along with Rolf Singer, by the Mycological Society of America in 1986.
