Fungi and fern

I spotted these on top of an old stump a couple of days ago when I stopped to pick up the mail. They remind me of tatties! Wouldn't put them in my mince though. 
It was a cool 8 C when I went for a walk this morning but it warmed up a bit. It was perfect for doing a couple of hours of work in the garden, cleaning up and turning the soil in the bed where the garlic will be planted. I'll probably work some manure in tomorrow then plant later in the month.
