Upside Down Mushroom.

The first mushroom is growing strong. It's still pretty small but has increased in size by about 750% in 24 hours (that's a rough estimate).

The strange thing is that it's coming in upside down! I have read that you need to position the cake with the same vertical orientation as it was when the mycelium was forming. Perhaps we have it upside down?

We'll continue to observe and if other mushrooms grow upside down we'll flip the cake.

Mushroom primordia

The first little shiitake to poke its head out. Cute!

A Primordia is a tiny baby mushroom. At first it looks like a very small dot  growing in the mycelium cake. The dot grows larger and becomes the mushroom cap.

At the time of this picture there are a half dozen smaller primordia showing around the cake.
