The wine cap (Stropharia rugosoannulata), also called king stropharia, garden giant or burgundy mushroom, is a large, robust agaric whose smooth, domed cap ripens from deep wine-red and burgundy to a fading reddish-brown, carried on a stout white stalk fitted with a thick, wrinkled, star-shaped ring. Meaty and mild, it is widely cultivated on wood chips and is prized for a savoury flavour often likened to potato, asparagus and red wine.
