Agrocybe Aegerita (Chestnut Mushroom, Velvet Pioppino, Agrocybe Cylindracea, Yanagimatsutake, Zhuzhuang-Tiantougu)

Agrocybe aegerita - Also known as the Chestnut mushroom, Velvet pioppino, Agrocybe cylindracea, Yanagimatsutake, Zhuzhuang-tiantouguAgrocybe Aegerita is a species of mushroom that belongs to the white rot fungi but looks like the button mushroom, only darker. It has gills whose colour ranges from pink to dark brown. Hence the mushroom is sometimes referred to as ‘brown cap mushroom’. It behaves almost the same as some other species of mushroom like the Tricholomamatsutake,, Agrocybe Aegerita and Agrocybeparasitica.

This genus of mushroom has about 100 species spread all over the world with some of them deadly poisonous. Since some of the species look very much alike, only an experienced person can safely identify the edible ones. The chestnut is tasty and meaty, and is palatable whether raw or cooked. Nevertheless, if you are not a trained eye, it is better to leave mushroom picking alone and respect the wisdom of the Croatian proverb: ‘All mushrooms are edible, but some only once’. An example of a very poisonous mushroom is the Amanita.

Cultivation of the chestnut began with the Greeks and the Romans and before that they collected truffles. In their traditional beliefs, mushroom emerged when lightning struck. Today, however, the chestnut is farmed and marketed in Korea, Japan, China and Australia. The Chestnut is medium sized and has an open and convex shaped cap. Underneath the cap are numerous radial plates that are white in colour. They later turn brownish grey. Sometimes it looks flat with a diameter of 3-10 cm. It is also referred to as the Poplar mushroom, possibly because it grows in holes on the poplar tree. However, it also grows in clusters on logs an on other trees with large leaves.


The Chestnut as a Dish

The Chestnut has a strong taste and fits well in different dishes. It goes in sauces, salads, pasta, quiches, soups, casseroles, omelettes, among others.

Fresh foods lose their flavour and nutritional value if not kept properly. This preservation of nutrients is paramount especially because many of the elements in the mushroom have medicinal value. When taken in food, the medicinal elements ensure various ailments are kept at arm’s length and the consumer leads a relatively healthy life.


How to store the Chestnut

To ensure the Chestnut mushroom retains its flavour, its nutritional value and edibility, it needs to be well washed, towel dried, kept in a fridge. The ideal length of storage is 3 days. The mushroom should not be wrapped in a plastic bag. If that happens, it will begin to sweat and start going bad in no time.
