mushrooms at 70-75° E (21-24° C.). Strains of this mushroom vary in their sensitivity to light and
carbon dioxide levels.
Mycelial Characteristics: White, longitudinally linear, becoming finely appressed and tinged light
brown to spotted with golden yellow brown zones with age. The surface roughens, resembling fine
sand paper, and sometimes becomes beaded at the earliest stage of primordia formation. Long
stemmed, small capped mushrooms commonly form along the inside periphery of the petri dish or
during cold storage of culture slants.

Fragrance Signature: Grain spawn musty smelling, not pleasant.

Natural Method of Cultivation: Stump culture is possible, as evidenced by the penchant that this
species has for logs, stumps. and wood debris in the wild. However, stump culture should not be encouraged to those who can not distinguish Enoki mushrooms from the small, wood decomposing
poisonous mushrooms such as the deadly members of the Genus Galerina or Gonocybe.
