Bridgesii dry rot?

Hey guys, I got two bridgesii that show signs of rot I think:
 There are only these tiny black spots, like tiny bubbles. It's hard to see but another bridgesii showed the same spots about 4 weeks ago and today looks like this:
 On this cactus I tried to limit the water, but it didn't seem to slow the spreading down.
Both cacti are grafted onto pereskiopsis btw.
Is that dry rot? what can I do to treat it? Do I have to cut the second one to stop the spreading?

Yea that’s the black spot of death. It spreads like wildfire if you let it. Cut it off. That’s become my practice for small patches for that. It’ll scar the cacti but might stop the spread. That fungus is voracious and will spread through an entire crop very fast in high humid conditions.
It might be able to travel through the vascular tissue or the plant...
There’s no control method other than trying to let no water at all touch your cacti.

Iv had may Trichoceeus that get black spots and iv never cut them out normally they heal them selves without surgery. Sometimes they will ooze black stuff but iv never had it spread throughout the cactus. I live in a dry climate so maybe thats why they heal without issues. I personally wouldn’t worry about unless it starts to spread.

Yeah, I read that thread too, thats why I decided not to cut the spot in the second pic initially. But since it was growing at the edges (but in deed seemed to heal and scar in the center of the black spot) I decided to cut that cactus back now. I did cut out the tiny spots on that small graft, it was about 10 little spots. But there is something positive: I did cut a big part of the bigger cactus which allowed me to try some things with te clean looking tissue. I grafted a part on a myrtillocactus and did a few aereol grafts on peres. I keep tem separated from my other cacti in case the grafted tissue is infected too.

I hear this alot and exercise caution. I have one spot but since my plants are inside a high tunnel, I'm letting sunlight and dry conditions do their work; while monitoring for any spread.
