Marasmius bulliardii Taxonomy and Etymology
This mushroom was described in 1878 by Lucien Quélet, who named it Marasmius bulliardii.
The genus name Marasmius comes from the Greek word marasmos, meaning 'drying out'. Elias Magnus Fries, who separated the Marasmius genus from the similar white-spored Collybia fungi, used as a key differentiating factor the ability of Marasmius mushrooms to recover if rehydrated after drying out. Fries called this drought survival characteristic 'marescence'.
The specific epithet bulliardii honors French mycologist Jean Baptiste Francois Pierre Bulliard.
