Marcel Josserand (5 October 1900 – 28 March 1992) was a French mycologist.
He devoted the greater part of his life to the study of fungi, especially those normally described as mushrooms (that is, agarics).
In 1923, he co-created the Mycological section of the Linnaean Society of Lyon, of which he was later president at various times.
From 1938 he collaborated with the famous mycologist Robert Kühner in Lyon.
[2] Two examples of fungi for which he was the name author are Macrocystidia cucumis (Pers.)
