The mushroom is a fungus whose developed offshoots grow in or under certain trees. In a relatively warm and wet country in which over 75 per cent of the land is covered by mountains, mushrooms grow in abundance and are used in everyday cooking. Apart from the most popular ones, introduced below, there are the Japanese equivalents of European mushrooms such as hiratake (oyster mushroom family), maitake (hen of the wood), amigasatake (morel), amitake (boletus) and anzutake (chanterelle), as well as numerous regional seasonal varieties available locally.
