Medicinal Properties: An unpublished report from the National Cancer Institute of Japan by
Ikekawa (1990) showed strong anti-tumor activity. Mice were implanted with Lewis Lung carcinoma
and given aqueous extracts of the fresh mushrooms. At a dose equivalent to 1 gram/kilogram of body
weight per day, tumors were 100% inhibited, resulting in total regression. Control groups confirmed
that, in absence of the mushroom extract, tumors were uninhibited in their growth. No studies with
human subjects have been reported.

Flavor, Preparation & Cooking: A superior edible mushroom with a firm, crunchy texture and
mildly sweet nutty flavor, this mushroom is highly esteemed in Japan. Versatile and enhancing
any meal, H. tessulatus goes well with vegetable, meat, or seafood stir-fries and can be added to
soups or sauces at the last minute of cooking. The flavor dimensions of this mushroom undergo
transformations difficult to describe. Buna-shimeji can be incorporated into a broad range of
