Yellow Stainer - Agaricus xanthodermus


    The cap is white and may have lobed edges. It is often smooth except for the centre which is usually slightly scaly. Cap width is 5 to 10 cm. The name derives from the fact that if the fungus is bruised or scratched a bright yellow stain will appear. A good test is to cut open the base of the stem and if it stains a strong yellow colour it is a likely to be Agaricus xanthodermus.
