Buna Shimeji

Strain Profile

Buna Shimeji is a popular edible mushroom native to East Asia.  It is farmed extensively in Japan.

Most often the mushroom is found on beech trees, hence the common name, beech mushroom.  

Best yields are to be had on supplemented sawdust.  It is possible to cultivate on straw, but yields are too small as to be commercially viable.

Buna Shimeji have a slightly buttery, nutty flavour, and a firm texture.  Versatile in cooking, they can be fried, stir-fried, or added whole to soups or stews.

This strain fruits from 13-18˚c.
