Nannfeldt studied natural history at the University of Uppsala and obtained a doctorate degree in 1932.[2] He became professor of botany at Uppsala University in 1939, a position he held until his retirement in 1970.[1] He did numerous studies on the systematics of fungi and vascular plants. Among the groups he treated were the plant pathogenic rust fungi,[3] smut fungi[4] and Exobasidium.[5] He also treated taxonomy and biogeography of various groups of vascular plants, e.g. the arctic Poa laxa complex.[6]

Nannfeldt published the exsiccate work Fungi Exsiccati Suecici, praesertim Upsalienses together with Lennart Holm and others.

He was elected member no. 983 of the Royal Swedish Academy of Sciences in 1955.

The cup fungus Plectania nannfeldtii is named in his honour, as well as the genus Nannfeldtiella.[7]
