It exhibits a clumping, polycarpic growth habit, uniquely characterized by dense feathery tubercles uncommon in other Mammillaria species. Cylindrical tubercles 7-10 mm long, covered with white feathery hairs up to 15 mm; stem globose to slightly elongated, 5-8 cm diameter; lacks rigid spines, only feathery hairs ranging from white to cream.
