Dog lichen on lawns

The scientific name is Peltigera. It can be seen on a lawn as a curious black and white growth which is very striking in appearance. It is a sign that the lawn is a very bad shape as it occurs on soil lacking in nutrients.

The main way to control it is to improve the growing conditions in the lawn, discouraging it from spreading. Improving the grass will prevent it returning.
