Dutch mycologist Jakob Emanuel Lange was born on 2nd April 1864. Having first worked as a gardener, in 1888 he took up a teaching post at the agricultural high school in Dalum bei Odense, in Denmark, and throughout his life he maintained a passionate interest in fungi; his mycological research work and publications were largely focussed on the systematics of agarics (gilled mushrooms).
