mousseron

From Middle French mouceron, from Old French moisserun, moisseron (compare Late Latin mussirio, Occitan mossalon, Catalan moixernó), of uncertain origin. Probably ultimately derived from Old French mosse, moise (“moss”), from Proto-Germanic *musą, as the type of fungus so-named applied to one which grows in moss. More at mushroom.
