Discovery of two biological species within putative Lentinula boryana led t
o examination of type specimens of names previously listed in synonymy unde
r L. boryana. Shape of cystidia and spore dimensions were diagnostic in ass
igning each type collection to a morphological species. Armillaria raphanic
a is the most priorable basionym representing the "non-boryana" taxon, and
the epithet is recombined in Lentinula.
