Looking at it I would call it Trichocereus bridgesii but I would like a clear picture of the tips to be able to confirm this. I'm sure it is but if you could supply a couple more pictures that would be great.

It's a Trich and almost certainly active... but could be any number of hybrids, classification is a bitch.
They look more like my Pachanoi's than my Bridgesii.. but as I say there are so many hybrids I'm not even certain many of mine are what they were sold as. Some have huge spines, some almost none. Ridge numbers can vary per species as can areole placement. 
eat em and see, or wait for Cactus Dan to chime in and set us straight..

Certainly bridgesoid.
Looks similar to some that were offered a year ago at the same place by a different seller. Those were likely 'Killer Green Cactus; and these look like it too. Supposedly quite the potent strain from a very old mother plant in So. Cal.

Yeah it looks like it would be pretty potent. It's a great looking specimen.

The word is that these cuttings are from a wild Bridgesii cactus in Southern California. The thing that made me question the accuracy of this story is the fact that Bridgesii is not native to Southern California. In fact, I recall reading somewhere that the first “San Pedro” specimens were not introduced into the USA until the 1920s. So how could Bridgesii be growing wild in SoCal? Does anyone know the history of trichs in the USA? How can one tell the difference between pachanoi, Peruvian and bridgesii? Is there a definitive guide anywhere?

i would think it's all subjective, things happen at a different rate, people introduce things as they please, no telling ......

It looks very similar to an incredibly potent strain of bridgesii.

It's not wild in the sense that it is native to California. Trichocereus bridgesii is native to Bolivia only. The history of Trichocereus is cultivation is muddy at best, but it seems that cultivation didn't really start to become widespread until the early 1900s. Luther Burbank of the Burbank-Russet potato grew a hybrid as part of his experiments with cacti.
If I am correct about the origins of those cuts--not the seller but the plant it came from--it has been said before that the man who owns the piece of land that this specimen grows on lets it grow 'wild' in the ground without fertilizer or water and allowing it to bend and fall. Perhaps 'naturally' would be a better description.

naum, thank you for the info. You seem to be quite knowledgeable about SoCal cactus growers. What are there like 2 or 3 of them? LOL
Here are some pictures of the tips of these cacti. I would like other people's opinions on what these are. I am new to the world of the majestic cacti and would like some tips on how to identify the various species. Thank you you all!

Thanks for the new pictures!
It is definitely a bridgesii. A very one at that.
If you're interested in learning to id your own I would start with San Pedro. Here's a guide on how to distinguish these from other columnar cactus>>link
The main cactus that is often confused with this one is Cereus peruvianus and similar Cereus species. Once you learn to identify San Pedro you can move onto the others. Here's a link on the differences between T.pachanoi, T. peruvianus and T. macrogonus.>>>link
Trichocereus bridgesii is very distinct from the other active columnars and often have large honey coloured spines up to 3 inches in length. These are in clusters of between 3-5 at the areole, depending on the type you have. The epidermis is also different from San Pedro. It will have a nice Blue-Green hue to it while the San Pedro usually is just a nice green.
Just look at pictures online and compare the differences. In no time you will be a cacti master.

Great post karode, nice links in there. It is a minefield with all the hybrids/mislabeled plants out there.

Thanks for the links karode! Fascinating stuff! I have few other questions though. How will mold on the tip of a cactus cutting affect rooting? What can be done about cactus mold? Take a look at the picture below. This just developed in the last day or so. Do you think I should just put it in some cactus soil now?

It'll need another 2 weeks before you can plant it I think. You want that cut to feel like bark and be quite thick. This forms good protection while it's rooting and is worth waiting for.
The mould is hard to see clearly in those pictures but I think it's fine. If you can smudge it with your finger you could wet a tissue with isopropyl alcohol or similar alcohol and wipe it away. The alcohol will kill the mould or you can put it somewhere with better airflow to help the callus form, which will prevent the mould forming or spreading further.
If it was a red coloured mold that doesn't rub off then I would be a little worried, this is the mould responsible for rot in most cases. As it is the mould won't affect rooting.

That is almost certainly Trich. bridgesii. The long spines and the thickness of the ribs seem to make that the highest probability. And I know for a fact Bridgesii grows really well in the desert southwest of the US, especially in the cooler, dry mountain regions, which have a climate and soil composition that is almost identical to the native regions of bridgesii.
And what do I think? I'd like to take all three pieces and chew the skin up...
