Mushrooms are not known to grow on the beach itself. However, unusual species grow in the beach ridge, living off of the dead roots of marram grass. Examples are dune brittlestem, Melanoleuca cinereifolia and stinkhorn. You find lots of other mushrooms in dunes further away from the coast which are otherwise very rare in other biotopes. Examples are collared earthstars, the waxcap Hygrocybe acutoconica, butter waxcaps and morels. Since coastal regions take much longer to freeze than inland, mushrooms are often found in the dunes practically year round. Dune woods are renowned for their abundance of mushrooms.
