In the spring I "sow" some mushrooms in a shady part of my garden - Blewitt (Lepista nuda), Wine Cap (Stropharia rugosoannulata) and Elm Mushroom (Hypsizygus ulmarius).
The mushroom spawn I sow came in the form of mycelium sprinkled on various kinds of seeds (at least looked like this). I prepared the mushroom beds as a mixture of straw, sow dust and autumn leaves depending on the requirements of the different species.
Yesterday I noticed that some mushrooms have just sprouted.
I would like to have the sown mushrooms as a permanent addition to my garden, so I am wondering whether to gather the mushrooms or let them get big and hopefully spread through the whole mushroom bed.
If I am to gather them, should I cut the mushrooms, or twist them?
I live in zone 6.
EDIT: After letting the mushrooms get big enough, I realized they are none of the species I have bought, so I am not eating them. Nevertheless, when hopefully I get sprouts of let's say Garden Giant, what would you suggest doing with the first crop?
