15, see text Lentinellus is a genus of white rot, wood decay, lamellate agaric in the family Auriscalpiaceae, further characterized in part by rough-walled, amyloid spores produced on lamellae with jagged edges.

Typically, thick-walled hyphae in the fruit body are in part amyloid, and frequently the taste of the mushrooms is acrid (burning, spicy).

[2] Mycologists Ronald Petersen and Karen Hughes considered 24 species in their 2004 world monograph of the genus.

[3] The name Lentinellus is the diminutive of Lentinus, which is the generic name for another group of wood-decay fungi with rough lamellar edges.

[4] Closely allied genera are Auriscalpium and Dentipratulum, with Artomyces slightly more distantly related.
