A single stand of mushrooms forcing their way through the tarmac of a pavement,
This is the third year in succession that the same species of fungus has grown, at the same time of year, in the same spot.
The first time was only a few weeks after the tarmac had been laid.
The hole where the tarmac is pushed aside by the growing mushrooms expands every year.
These pictures are in sequence, and show the development of the mushroom clump over the course of a week after I first noticed they were there.
