Heinrich Simon Ludwig Friedrich Felix Rehm (20 October 1828, Ederheim – 1 April 1916, Munich) [1] was a German mycologist and lichenologist. He studied at the Universities of Erlangen, Munich and Heidelberg, earning his medical doctorate in 1852. During his career, he was a practicing physician in Dietenhofen (from 1854), Sugenheim (from 1857), and Windsheim (from 1871). In 1875, he became regional medical examiner in Lohr am Main.[2]
Starting with 1869 until his death Rehm distributed exsiccata specimens in five series, one of them co-edited by Ferdinand Christian Gustav Arnold.[3]
