Hi, I'm wondering what these black growths are on my pathos stem. They seem to have appeared over night and are all along the plants stems. The plant is in good health other wise. And I'm not talking about the nodes.

This is the beginning of the growth of air roots. Potos has 3 types of roots: underground, air roots for plant nutrition and air roots, which help the plant to hold on to the support.
Rapid growth of air roots indicates the presence of high humidity.

Whats the 3rd type of root?

it roots can grow in soil, air and water.

Not sure, looks like aerial roots are drying , out need to spray.

I keep my apartment at 69F could it really be humid in that low of a tempature? It doesn't ever feel humid... I have other pothos plants that are the same age and size that don't have these spots. Why would they not be getting the same air roots?

Not die, dry.

I would have sprayed water, adjust spray bottle nozzle to mist.

I might be wrong, pothos gives roots at nodes only.

A decrease in temperature of an air mass results in an increase in relative humidity. The air gets dry in the winter because no water evaporates because its too cold.

This can be observed by leaving an object in the freezer, and then taking it out. It cools the surrounding air, until the humidity exceeds 100% and water begins condensing on it.

The root system is fibrous. (Roots in the ground are 3 type )
Stems also have numerous air roots, from which an additional root system can develop under favorable conditions.
Air roots of two types:

1. roots of the nodes that will help the plant to hold on to the support.

2. Feeding roots appearing from the internodes. These roots can take root in the soil. Sometimes they remain free.
Both types of roots with age are lignified:
Clinging roots become cork, and feeding roots - wood by structure .
In any case, it is normal for plants. :)
