Fungi

The main fungi season has arrived.
This is a Common Puffball. Lycoperdon perlatum.
It will be known to most blippers I think.

When it matures a hole opens in the top. When it is touched or when it is hit by raindrops vast numbers of spores are puffed out and drift away in the wind.

The books say it is edible when young but it can be confused with another species which is not to be eaten. So I would not recommend it.
