, which is the generic name for another group of wood decay fungi with rough lamellar edges. The type species and the best known is L. cochleatus
, which was classified as under Lentinus by Persoon in 1825. Later it was realized that the species now in Lentinellus are very different in other characteristics from the other Lentinus species, and in modern taxonomy the groups are put into quite different orders (Lentinus is in Polyporales
whereas Lentinellus is in Russulales
).
Closely allied genera are Auriscalpium
and Dentipratulum
, with Artomyces
slightly more distantly related. These groups are non-agaricoid but, strangely enough, Lentinellus is more closely related to them than to other gilled mushrooms.
Agaric
An agaric is a type of fungal fruiting body characterized by the presence of a pileus that is clearly differentiated from the stipe , with lamellae on the underside of the pileus. "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body...

Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...
Auriscalpiaceae
Auriscalpiaceae
The Auriscalpiaceae are a family of fungi in the Russulales order. Like much of the Russulales, it has been defined through molecular phylogeny, and includes physically dissimilar species, such as the tooth fungus Auriscalpium and the gilled, often shelf-like members of Lentinellus. The family...

Amyloid (mycology)
In mycology the term amyloid refers to a crude chemical test using iodine in either Melzer's reagent or Lugol's solution, to produce a black to blue-black positive reaction. It is called amyloid because starch gives a similar reaction, and that reaction for starch is also called an amyloid reaction...

Mushroom
A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus; hence the word "mushroom" is most often applied to those fungi that...
