Just a quick update on my mushrooms which are hidden away in my garage at the moment. At about week 2 a tiny mushroom like fungus appeared on the surface of the compost, then grew into a 3" tall stalk of spaghetti, then died the next day! The instructions on the packet said that mushrooms should appear between 10 and 12 weeks, so I suppose that was a bit premature to hope. They seem to be growing a very definite white mould underneath the surface. I remember from my biology lessons that this is called a 'mycelium'. No signs of life yet, but will keep posted. Above is a picture of sowing the spawn from the packet. I think it was stuck onto rice grains.
