Matsutake mushrooms

Matsutake mushrooms, the highly-prized autumnal delicacy revered by fine-diners in Japan, are the world’s most expensive mushrooms.Japanese mushroom their disappearing habitat in Japan means the price continues to climb Japanese mushrooms.

Of the genus Tricholoma, with the name Armillaria ponderosa, they are not as expensive as, say, white truffles, but Japanese Matsutake mushrooms are the most expensive mushrooms in the world. They have a rich autumnal flavour, a meaty texture and sweet aroma that is sought after by master chefs for matsutake recipes in ryōtei restaurants.

The matsutake mushroom, closely related to the Tricholoma magnivelare found in the pacific northwest, has a long and storied history in Japan and South Korea. Mentioned in a seventh-century collection of Japanese poetry, Manyoshu, the delicious fungus has been enjoyed by residents of the cities of Kyoto and Nara for over a thousand years. The matsutake mushroom was often given as a gift by the aristocracy and even members of the Imperial family. Signalling the change of the season, the brown-scaled matsutake mushroom has, over centuries, become a potent symbol of Japanese culture.

The large fungi, once a common site in Japan’s autumn markets, and easily found on the forest floor, are no longer in such plentiful supply, however, and as they are virtually impossible to grow artificially, demand continues to rise.

What Price are Matsutake Mushrooms?
If you want to enjoy the unmistakeable, autumnal flavour of matsutake mushrooms, you will have to shell out. They may not be as expensive as some of the other high-end fungi like white truffles, but selling for about $1000 per pound (about €900 for 0.5 kg), they can be compared to some rare varieties of black truffle. A typical punnet of about eight mushrooms can cost as much as $500.

Why are Matsutake Mushrooms so Expensive?
As disposable income in Japan has increased in the last few decades, coupled with the increased status of the mushroom in Japanese culture, demand for matsutake mushrooms has continued to grow. Depletion of the mushrooms’ habitat – the red pine forests, which have come under attack from the pinewood nematode, an invasive worm originally from North America – means supply of the fungi is ever-diminishing. The total annual harvest in Japan is now under 1000 tonnes.

What are Matsutake Musrooms used for?
Matsutake mushrooms are often given as gifts, sometimes by companies to clients in season hampers. They are commonly used in sukiyaki, a nabemono-style one-pot dish combining dashi, sake, mirin, and sugar. They are also used in matsutake gohan, a steamed rice dish made with kombu dashi, soy sauce, sake, and mirin. Because of their unique flavour profile, the mushroom us usually not over-worked and instead they are enjoyed thinly sliced, in hot soups or with steamed rice.

How to Identify Matsutake Mushrooms?
The Japanese matsutake mushroom is of course a rare delicacy that can only be found in the red pine forests of the country. They are a pine mushroom which have a symbiotic relationship with the roots of certain pine and coniferous trees. The closely related matsutake mushroom of North America can be found in pine forests at altitude quite easily. The matsutake mushroom can be identified by its spicy, organic smell. They are white with brown stains that could look old or grubby. The gills are white, and as with all Tricholomas, the spore print is white.
