He completed his medical studies at Charles University in Prague before practicing as a specialist in internal medicine in Turnov and Mnichovo Hradiště, in northern Bohemia.
[2] He devoted much of his career as a mycologist to the study of his favourite genus, Lepiota, but he also worked on the genera Agaricus, Armillaria, Cortinarius, Entoloma, Mycena, Omphalina, and on the species Helvella gabretae, Xerocomus moravicus, among others.
His herbarium samples, preserved in the Mycology Department of the National Museum in Prague, are accompanied by meticulous descriptions of the characters observed in the fresh state (color, smell, taste, consistency, etc.).
He was co-author of the red book of the cryptogamic flora of Slovakia and the Czech Republic published in 1995, where he listed twenty species of agarics and boletes, illustrated by his younger brother, the painter Jan Herink [cz].
He presented numerous lectures to the mycological society, not only on agarics and boletes, but also on poisonous mushrooms and on nature conservation, the last, three months before his death, on the genus Clitocybe.
