Organic Elm Oyster - Hypsizygus ulmarius - dowel spawn

Synonyms: Tree oyster mushroom, Oyster Mushroom, Hiratake, Tamogitake, Píng Gu, Sadafi, Chippikkoon

The elm oyster mushroom is a relatively rare mushroom, which usually grows singly or in small groups on elms and beech. The Hypzisigus ulmarius closely parallels the morphology of an Oyster mushroom but has more depth in flavour and texture. This mushroom can become quite large (4 - 15cm).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 Oyster mushroom. The colour of the fruiting bodies is white to light grey or light brown, depending on substrate and habitat.

This fresh product is prepared fresh for you to order. The production time is around 3 - 6 weeks.
The mushroom spawn should be processed immediately after delivery.
If the product cannot be processed immediately, it can be stored in the refrigerator at 4 °C for up to 2 weeks.
We recommend that you plan for this when ordering.

You receive fully colonised spawn dowels for inoculating wood logs
​ 1 Pack with 500 dowels is sufficient for 5 wood logs
1 Pack with 1.000 dowels is sufficient for 10 - 20 wood logs

Inoculation with spawn dowels is traditionally used in mushroom gardens and recommended for beginners. Depending on the species, mushrooms can be harvested over several years - until the fungus has depleted all nutrients in the substrate. The fruiting bodies typically appear from the second year onwards and continue for 3 - 5 years, coinciding with the mushroom season. The expected harvest yield is approximately 10 % of the fresh woods weight, spread out over multiple harvests during the 3 - 5 period.

For quantities of 10 logs or more, inoculation with sawdust spawn is usually more efficient than working with spawn dowels.
