Until recently, the species was considered to be conspecific with the European Flammulina velutipes, but DNA sequencing has shown that the two are distinct. Etymology. In Japanese, the mushroom is known as enoki-take or enoki-dake, both meaning "hackberry mushroom". This is because it is often found growing at the base of hackberry (enoki) trees.
