These appear to be everywhere in Ginko's world, depending on the area he's traveling through. I suspect he sees more than we know about, given their density in any given area when he chooses to pay attention to them.
These seem to have the most variable shapes out of all the mushi; perhaps that's because any mushi can get weak and fall into this category--though many of them tend to look like flowers or snakes, perhaps because many mushi happen to look like that already.
There are a couple I would like to especially note here; one of them is more headcanon, and the other doesn't have a lot of information about it.
This type appear once, in a flashback. I believe they're something akin to will o'the wisps, in that they may lead travelers astray, should they choose to follow the light... but it's nothing malicious. They're just glowing jellyfish things that float around randomly in the forest.
Ginko's mushi-smoke.
Ginko appears to have the ability to manipulate the smoke he exhales. At one point he claims it's a 'friendly mushi' but nothing is known why that mushi in particular likes the smoke that all other mushi are supposed to hate, or how Ginko controls it, or why it doesn't hurt him when he inhales it. It's possible that this mushi is the real reason behind why other mushi don't like the smoke, and also what keeps Ginko from getting sick. In any case, it's pretty neat, though I usually don't reference it simply because so little is known about how it works. It doesn't show up again after the first episode.
