recall some forms of  M. humboldtii.  What a beauty!

 

Description: It is small growing cactus that look like a little golf ball.  It usually stays solitary, or occasionally clusters from the base.
Stems: Globose or slightly elongated as it ages, 2 - 3.5 cm in diameter and height. (In cultivation it can grow very slowly up to 8 cm tall).  Without latex.
Tubercles: Closely set, cylindrical, terminally truncate. The axil is naked.
Radial spines: 100 or more, unequal, interlacing, bristly, white or grey, 1-5 mm long.
Central spines: Absent.
Flowers: Diurnal, quite large for a Mammillaria, pale pink to red-violet, 20 - 25 mm long and very showy.
Blooming season: April to May, it starts flowering when it gets to be 5-7 years old, and reaches at least 3 cm in diameter.
Fruits:
Globose, whitish, small.

The 100 or more white radial spines create a lacy and friendly surface, smooth to the touch.

Cultivation: This plant isn't famous for being easy to cultivate, but in good conditions with excellent ventilation, it grows without difficulty.  It is especially sensitive to overwatering. So careful watering and an open mineral potting soil are a must.  Avoid the use of peat or other humus sources in the potting mixture.  Don't add limestone to the potting mix (which must be moderately acidic).  It can be sensitive to frost (but if dry they are resistant to -5 C).  Requires maximum sun exposure to reach its full potential, and  to achieve success in flowering.  A winter rest that allows the plant to shrivel (perhaps losing up to 25% of its summer height) will encourage flowering and long time survival.  Be careful to encourage slow growth.  Provide very good ventilation.
Propagation:
Direct sow after last frost. (it usually doesn't  produces offsets).
