What any mutation cannot change is the spine collor.
They can affect size, shape, and aragement(in the case of eulychinia spiralis) but not color ,and they cannot change growth habit without distorting the stem.
Acantrocereus tetragonus is a sprawling bushy plant. Absolutely no mutation would cause it to grow upward, upright, with dense, cereus-like habitat/
Monstrose and crestate cereus, like the so called ming thing, still retain the baseline cereus shape, spine color, stem color, and uprright growth pattern, while its it size and rib shape are distorted.
Monstrose and crest cacti have the ability to"shake off the mutation" producing healthy semi normal tissue resembling the species which they originate from.
Monstrose cerei, both dwarf("minor"), regular and otherwise, do that thing.

This is conclusive proof that "ming thing" is not acanthocereus tetragonus as well, as your database would erroneously like to dictate...
