The author considers Marasmius wettsteinii Sacc. et Syd. ss. orig. (= M. tenerrimus Wettstein, non Berk. et Curt.) and M. wettsteinii ss. Favre (1952), Hôhnel (1914), and Podzimek (1930) as the same fungus. The differences between M. wettsteinii and M. bulliardii Quél. are discussed. On the basis of these differences, the author proposes to consider these two taxa as separate species. The neotypus of M. wettsteinii is designated.
