Description: Turbinicarpus pseudomacrocheleSN|12810]]SN|12802]] subs. lausseri, best known as Turbinicarpus lausseri is a tiny solitary cactus species, but occasionally the root bears several stems.
Stem(s): Body flattened globular cylindrical, 20-40mm high 25-35mm wide dark green.
Ribs: Spiralling, divided into low and rounded conical tubercles 3-5mm long.
Areoles: In new growth with white wool.
Root: up to 8 cm long taproot.
Spines: Only radials- 3-12 yellowish-brown becoming greyish mostly erect bristly and twisted 15-30mm long. Juvenile spines at the base of the stem ± radiating and pectinated, 2-4 mm long.
Flowers: from the areoles at the apex reddish-purple 25 mm long, 25 mm wide.
Fruits: The fruit is green almost round 4-6 mm diameter and bears the dried remnants of the flower. It opens with a vertical slit when ripe.
Remarks: This taxa is closely related (or identical) with Turbinicarpus pseudomacrochele var. sphacellatus and very similar to Turbinicarpus krainzianusSN|12802]]SN|12810]] too.

Cultivation and Propagation: This species is fairly robust and easy to grow. Watering should be rather infrequent to keep plant compact. The fact that the plant retracts into the soil and assume a grey-green colouring between watering, is perfectly natural and doesn’t cause any damage. Hardy to -4°C for a short period.
Exposures: Full sun where it obtains a flat natural looking or part sun.
