The Stropharia rugosoannulata is a large massive mushroom first found in North America in 1922, and subsequently as well in Europe, New-Zealand and Japan.
This mushroom is easy to grow in beds of straw or wood chips.
Cultivation can be started in spring or after summer. The straw or wood chips are inoculated with the fungus on the spot, and should be covered in a 5 cm layer of casing soil, just like common mushrooms.
Do not pasteurize the straw or substrate. Use only fresh straw that is yellow and has a smooth structure.
Just like common mushrooms, the Stropharia rugosoannulata needs a layer of casing soil to stimulate the growth of fruiting bodies.
This casing soil contains bacteria that are essential to form fruiting bodies.
Contrary to common mushroom casing soil, there should not be used any lime in this casing soil.
The Stropharia rugosoannulata thrives on ground with a certain level of acidity.
Apply the casing soil after the substrate is fully grown with mycelium.
A proper casing soil can be made by mixing garden soil or leaf mold with peat dust fifty-fifty.
Again, do not pasteurize the casing soil. This way the mushrooms can benefit from the numerous bacteria.
