I'm having a little trouble identifying the plant type that I inherited from a previous neighbor, but I like the plant. It has, however, come down with a disease of some kind (or more than one I suspect). It is in a pot with another flowering plant that is doing fine, but the plant in question is doing horribly.

The disease(s) look to be some kind of combination of the black sooty mold and white mold (though it's not powdery--looks more like cotton or spider eggs). I've attached pictures of the plant itself along with the flowering plant in the same pot that seems to have no issue. I've also trimmed some infected segments and shown the upper and lower views for them. I've also taken a picture of what those segments end up looking like after a while after.

I'm not sure what the plant is or if it could be a plant-specific virus, but any help would be greatly appreciated. I have checked the pH level, which is about 6.7, and the soil seems to be a tad on the wet side, but that's easily counteracted by not watering. I've also tried to wash off the moldy areas, spraying regularly with Neem oil to no avail. The plant itself is in a corner of an apartment complex with ambient daylight, but only direct daylight for a couple of hours in the morning (I've not yet measured lumens throughout the day).

I would appreciate any advice! Thanks :)

Hi Anthony. Welcome to NGA.

I agree, it does look like more than one critter. Give this site a look. It has pictures of various pests that appear similar to some of your pictures.

Leaf miner, white fly and thrips do damage both indoor and outdoor plants.

Looks like a bad case of mealy bugs. I'm not sure why the other plant is doing fine.

I'm seeing mealies and (I think) whitefly. The sooty mold grows on their excretions.
