Using the refined method of experimentation the new tests worked! Below is a picture of tests three (B) and four where the mycelium was left to grow in substrates including cardboard, cotton calico and dead leaves. In one test I left the mycelium spawn to grow in between layers of bubble wrap to see how it would take the shape.
I left test four to grow for 14 days and tests three to grow for seven days to display the different stages of growth in my presentation.
