This Shiitake strain is very versatile. When grown at temperatures below 18°C, it produces beautiful fruit bodies of the donko-type: dark-brown, nicely scaled, heavy and slender-stemmed. The mushrooms of this species have a good shelf life. In warmer growing environment the flesh becomes thinner and the colour lighter. Mushrooms also appear between flushes.
This strain is very popular in Europe.

The Japanese name Shiitake consists of the words Take (= mushroom) and Shii (= Pasania-tree) and means mushroom that grows on a tree. The Shiitake has originally been domiciled in Japan, Korea and China and his special characteristics are known by the people for more than 2000 years. The smell of this special mushroom is very similar to garlic and is due to an ingredient called Lenthionine. Shiitake counts to the most popular gourmet-mushrooms in the world.
