Grifola

Grifola is a genus of polypore mushrooms that includes the species Grifola frondosa, commonly known as maitake, hen of the woods, ram's head and sheep's head. This genus is native to both the eastern part of North America and East Asia, and some species are cultivated and used for culinary purposes in both regions.

Taxonomy

The genus Grifola was first described by the British mycologist Miles Joseph Berkeley in 1851. The generic name is derived from the Greek grifos, meaning a kind of mushroom.

Description

Species in the genus Grifola are annual and grow at the base of trees, especially oaks. They are parasitic or saprobic, causing white rot in the host tree. The fruit bodies are large and can reach up to 100 cm in diameter. They are composed of multiple grayish-brown caps which are often curled or spoon-shaped, with a white spore print.

Species

There are several species in the genus Grifola, including:

• Grifola frondosa
• Grifola sordulenta
• Grifola gargal
• Grifola colensoi

Uses

Grifola frondosa is the most well-known species in the genus and is widely cultivated for its taste and health benefits. It is used in traditional Chinese and Japanese medicine to enhance the immune system. Research has indicated that extracts from G. frondosa have potential for use in the treatment of diseases such as diabetes, hypertension, and cancer.
