Etymology

''Contumyces'' is named after the contemporary amateur Italian mycologist, Marco E. Contu (professionally an Italian criminal court judge) and is a replacement for the illegitimate generic name ''Jacobia'', so named after

Jakob Emanuel Lange Jakob Emanuel Lange (2 April 1864 – 27 December 1941), was a Danish mycologist who studied the systematics of gilled mushrooms. His best-known work is ''Flora Agaricina Danica'', a five-volume plate work on the Agaricales of Denmark. He was als ...
