Naucoria scolecina Taxonomy and Etymology
The basionym dates from 1838, when the great Swedish mycologist Elias Magnus Fries described this little mushroom scientifically and gave it the binomial name Agaricus scolecinus. In 1875 the French mycologist Lucien Quélet transferred this species to the genus Naucoria, establishing its currently-accepted scientific name naucoria scolecina.
Naucoria, the genus name, comes from the Latin word Naucum meaning something slight or trivial. The specific epithet scolecina refers to the worm-like cheilocystidia on the gill edges of this mushroom.
