Yellow Stainer fungi

Agaricus xanthodermus, the ‘yellow stainer’.

The fruiting bodies of this species have a characteristic square shape. There are two forms, one that is pure creamy-white and this one with the brown speckles. Both have been found at Else Mitchell in March 2017. This mushroom is commonly known as yellow stainer due to the yellow colour that forms when the mushroom is damaged.
