Mushrooms / toadstools or what you will

A neighbour's pine tree dropped a lot of dead "leaves" onto the top of our old woodpile roof. It made the most amazing compost. So I filled a few pots with it and some other soil from the garden. There must have been lots of spores in the compost, because I keep seeing mushrooms in the morning. They have vanished by tea time, like they've gone for a bit of a stroll. Here are the latest little beauties.
