MUSHROOMS ON THE DUNES

Earth Star (Geaster hygrometricus)

Star-shaped fleshy skin at base Main, central body is round

The flower-like shape of this common mushroom always amazes its discoverer. The basal star is actually a protective coat that covers the ball during dry spells. Its scientific name, Geaster, means “earth star.” Hygrometricus means “water-measuring,” and refers to the opening and closing of the star.

GRASS ON THE DUNES

Beach Grass (Ammophila breviligulata)

Typical grass shape Sharp, stiff tip to blade

Beach Grass is the most common xerophyte here. It forms dense mats everywhere, and once it gains footing, spreads at a remarkable rate. When windy weather bends the blade it sometimes scribes circles in the sand. If these are deeper on one side or incomplete, they help determine the direction of the prevailing wind. Beach Grass can be extremely uncomfortable to bare legs—so beware!
