Forms flat grayish/brown to olive/green stems with (usually) three spider like spines per areoles, it is fairly rare in cultivation but easy to grow.
It is a dark skinned solitary Argentinian cactus with almost useless spines making it relatively easy to handle. G. riojense is one of the most variable Gymnocalycium. Will eventually offset after a considerable period of time.

Blooming season: Flowers are produced in late spring and remain open for up to twelve days.
Watering: needs moderate to copious waterings in summer, but do not overwater (Rot prone), keep dry in winter at a minimum temperature of 0°C.
Exposition: The plant tolerates extremely bright situations but enjoys filtered sunlight or afternoon shade, inside it needs bright light, and some direct sun. Tends to bronze in strong light, which encourages flowering and heavy spine production, but is likely to suffer from sun scorch or stunted growth if over exposed to direct sunlight during the hottest part of the day in summer.
Uses: It is an excellent plant for container growing. It always looks good and stays small. It look fine in a cold greenhouse and frame or outdoor in a rockery.
