Trichocereus pachanoi monstrosa “Clone A” is a mutant cultivar of Trichocereus pachanoi. There are two very common mutant cultivars of Trichocereus pachanoi. Sacred Succulents lists them as CLONE A and CLONE B. Please note that they are not the same as the two Trichocereus bridgesii Monstrosa cultivars that are also listed under that name. Trichocereus pachanoi “Clone A” is sometimes called Molten Wax Pachanoi or Melted Wax Pachanoi too. It forms thick fans of cristate growth and occasionally reverts to normal growth or monstrose colums that look very much like molten wax. It is said that no two plants are the same and it can be greatly variable.
Both Clone A and Clone B are extremely similar and I have doubts both are actually two different strains, and not just different manifestations of the same clone.
Trichocereus santiaguensis is a regional variety of Trichocereus spachianus. And this clone has been floating around for at least 20 years. It sometimes is labeled Trichocereus pachanoi or Trichocereus bridgesii. And though the spination very rarely comes through, it makes it obvious that this is absolutely not a plant from the San Pedro group. The epidermis has a bright green color, which is typical for Trichocereus spachianus as well. If you are interested in seeds of Trichocereus spachianus, you can get some high quality seeds here:
The Trichocereus santiaguensis monstrosa is a nursery produced cultivar that sometimes shows up on websites like eBay.
The Tr. santiaguensis monstrose is probably a nursery produced mutant that was grown from Ritter´s Trichocereus santiaguensis seed. It is also called green pepperoni cactus, cereus pepperone, and so on. There only were very few collections of this plant and it would be surprising to hear if it is unrelated to the stuff that was collected by Friedrich Ritter. All the seeds I bought were dead as wood.
Now let´s summarize what this plant is synonymous with:
Trichocereus spachianus monstrosa
Trichocereus santiaguensis monstrosa
Cereus santiaguensis monstrosa
Cereus spachianus monstrosa
Trichocereus santiaguensis monstrosa
Echinopsis santiaguensis monstrosa
Please note that this is NOT synonymous with Trichocereus santaensis, which is a regional form of Trichocereus pachanoi or Trichocereus peruvianus that looks substantially different and originally comes from the Santa Valley in Peru.
I also seen this labeled Trichocereus santiagoensis monstruosa, but I rather think that this is some kind of a spelling error. The plant grows mostly spineless and looks like a very thick spineless variety of a TBM. This plant is really rare and is not related to the two similar looking Lophocereus monstrosa cultivars that exist too. The spines are light brown and look like the spines on a standard Spachianus.
I am not sure how it got into cultivation but it is believed that this is actually a nursery-produced cultivar. The plant is sometimes available in our Trichocereus Facebook Group and I recently saw quite a lot of them offered for sale.

TPQC is another clone from SAB member Nitrogen. The ID of the species changed repeatedly in the past, but it is probably a Trichocereus peruvianus. It developed crested growth after an injury, but is generally not a crested clone and I have never seen one of the cuts revert back to crested growth. It is probably best to consider it a normal clone of Trichocereus peruvianus.
