Lentinellus micheneri is a species of wood-inhabiting fungus in the family Auriscalpiaceae. It was first described in 1853 by mycologist Miles Berkeley and Moses Ashley Curtis as Lentinus micheneri. David Pegler transferred it to the genus Lentinellus in 1983. Like all species in its genus, it is inedible.
