Dragon fruit parasite?

[allstarplayer220]

Hi,
I have a dragon fruit plant that is starting to grow some strange white stringy things from the plant itself. I have attached a picture of it to this message. I have been pulling them off, yet, a few days later, there are more!
Can anyone please identify what it is???

Is it very humid where you are? That looks like a root....

I'm from north san diego county, california. It has been very humid lately. I've also been spraying my dragon fruit plant with water a few times a week. So what your saying makes sense ! It's a new plant I started from a clipping a couple weeks ago so I thought foliar feeding the plant with water would help it take root quicker....
