Coryphantha ramillosa usually grows individually, but sometimes branches out and then forms groups. The spherical to broadly obovate, dark gray-green to grass-green shoots reach heights of 6 to 9 centimeters with a diameter of 6 to 10 centimeters. The apex of the shoot is often depressed. The ascending conical warts are up to 20 millimeters long. Nectar glands are usually absent. The up to four whitish central spines are protruding or spread out, straight to slightly curved and occasionally scrubby or twisted. They are 1.7 to 4 inches long. The eleven to 20 whitish, 0.9 to 3.5 cm long radial spines are usually straight.

The light pink to deep pink purple or shiny yellow flowers reach lengths of 3.5 to 6.5 centimeters and diameters of 3 to 5 centimeters. The very fleshy dark green to light gray green fruits have lengths of up to 2.1 centimeters.
