Echinocereus stramineus has many shoots and forms large cushions with up to 500 shoots and diameters of over 1 meter. The cylindrical shoots gradually tapering towards their tip are up to 45 centimeters long and have a diameter of up to 8 centimeters. They are usually covered by the thorns. There are ten to seventeen ribs that are not well humped. The one to four strong, round to slightly flattened, straight to slightly curved, initially straw-colored central spines turn whitish later. They have lengths of 4 to 8.7 centimeters. The seven to 14 initially pink to yellowish and later whitish radial spines are up to 3 centimeters long.
The broad, funnel-shaped flowers are bright magenta in color and appear at a considerable distance from the shoot tips. They are 6 to 12.5 inches long and reach the same diameter. The spherical, very fleshy fruits, red when they are ripe, smell and taste like strawberries. They are covered with sloping glassy thorns.
