This hybrid is normally called "Rampo-kabuto".
Both of myriostigma and asterias are Astrophytum but myriostigma has a yellow flower and asterias flower is yellow petals and orange throat. When you crossed differnt flower groups of Astrophytum, it may be happened a gene stress.
I can see the stress on your both plants.
The stress is called "Akebono han" meaning twilight varigation.
