Mistletoe Cactus in bloom

Rhipsalis sp. There are many Rhipsalis species of cactus, I have discovered. Perhaps someone viewing this photo can tell me which one this is. The blooms are yellow, and the individual joints of this cactus are rounded, not flat, and they are shorter than some are shown when I google this genus. They are also smooth, fleshy and not hairy, and spineless.
