These oyster mushrooms were growing from the sawn-off stump of a birch tree in a garden.
The soil was built up, perhaps level with my chest. That’s why these views show the undersides of the mushrooms and there are better views if the gills than the caps.
I don’t know whether it is cause or effect, but the mushrooms are sprouting from there the bark has peeled back from the stump.
Oyster mushrooms can vary in colour and be seen at any time of year.
