Winter mushroom - Flammulina velutipes

The Winter mushroom / Enokitake has a long tradition in Asian cuisine. One cultivation form of this mushroom is Enokitake. This type is produced under low lightening, in that way the mushroom makes small but very delicious fruiting bodies. The fruiting bodies have a diameter of 2-10 cm, the stem is 3-8 cm long. Enokitake produces white spores. It can be found in the cold and moderate climate zones on the northern hemisphere, e.g., China, Siberia, Asia Minor, Europe, North America and Japan; on the southern hemisphere in Australia.

Cultivation of Enokitake has a long tradition in China and was documented for the first time around 800 A.D. As soon as the fruiting bodies had grown to their full size, the cultivators of that time rubbed them on wood logs. With a bit of luck there was a good harvest in the year after. However, the use of spawn dowels, as practised today, is much more effective.

Ready colonised rye grain spawn for inoculation of convenient fruiting substrate. Larger quantities for commercial mushroom growing on request. Recommended only for experienced cultivators!

About the Mushroom

Scientific name: Hypsizygus ulmarius


Synonyms: Elm Oyster, Shirotamogitake, Da Yu Mo


Natural habitat:
The elm oyster is distributed all over the temperate climate zones in deciduous and mixed woodland where it grows mainly on elm, beech or oak trees. During the last centuries the population decreased, so it is not advisable to collect this mushroom from the woods.

Appropriate substrate:
Wheat straw, hardwood (most suitable: oak, beech, plum, maple, elm, birch, alder, ash)


Edible mushroom

The Elm Oyster is a delicious edible mushroom that can be used like other Oyster mushrooms. On the market this mushroom is often incorrectly sold as 'Oyster mushroom' but it produces larger fruit bodies than other Oysters. The colour of the fruiting bodies is white to light grey or light brown, depending on substrate and habitat.
