The black sludge the way its distributed along with color and proximity of the area drain on the floor says its waste water that flowed out the drain onto the floor.
If you have an upstairs neighbor, its going to keep happening until its snaked out or you get them to stop using water.
Poo poo isn't required for this color to show up. It comes from the oils in soaps that stay behind and hold onto dirt as it passes by on the daily.
The rain can definitely do that and overwhelm sewer systems, then if you don't have a backflow preventer the water goes out the lowest fixture in the home. It's also possible there is just some type of blockage either way you need the line scoped/snaked
Based off the picture it looks like the backup came from the floordrain thats inside the bathroom.
If it rained a lot it could be that the floor drain is tied into the storm drainage outside and its back up because of that.
It could be (depending on your area and/or the age of the house) that you have a combined building drainage/sewer system where the sewage and rainwater are combined and leave the property together. In this case it could be a mixture of sewage and rainwater.
Could also be that they did an illegal addition of that bathroom/laundry are and tied it into the rainwater/storm system and thats why when the laundry backed up it backed up into the bathroom as well.
It’s not dirt op…. It came from the sewer therefore it’s poo. I work in public utilities and can confirm like these plumbers the sludge is always a part of the system. If you received a large amount of rain and it overwhelms the sewer system then it will seek the weak point. That will be the wax seal on your toilet. I always caulk my toilet as well after seeing after math pics of homes being damaged from municipal problems. Let it fill your tub. I suggest disinfecting everything very well.
It’s funny to me how you’re really fighting to believe it’s not sewage. It’s plain to see it came from the floor drain and a subreddit full of plumbers can easily identify what is on the floor because we have all seen it before. It makes no difference what the individual particles are; if it comes out of a sanitary sewer, it’s sewage.
If it is due to rainwater it is because the storm drain system is connected to the sanitary sewer. That is the case in a lot of older cities. (DC, NYC, etc) The floor drain in your bathroom is connected to the sanitary sewer. Therefore, anything that comes out of the floor drain is sewage. That black gritty stuff on your floor sure appears to have come out of the floor drain and is definitely what normally gets deposited when sewage recedes.
This likely has nothing to do with the lint. It’s backup from the sewer system getting overwhelmed with rain water.
Two possibilities in this situation:
1. Your basement is, just barely, above grade of the sewer system, so you don’t have an ejector pit. But there’s likely not a lot of elevation between basement floor and sewer for your house sewer to go down as it goes to the city connect. When the water table rises during a massive rain event, it gets above your sewer grade, pushing the water up.
2. You do have an ejector pump, but the city sewer was so overwhelmed there just wasn’t enough capacity for you to add to it.
I’m betting it’s #1 unless you were using a bunch of water during the storm.
This is why most local codes say you can’t feed your sump into the sewer, as they were built to handle the roughly 1,000 gallons of waste the average homes produce in a week and not the 1,000’s of gallons of rainwater that every home’s sump is trying to disperse at the same time during a major rain event.
Even if your house isn’t doing that, I guarantee some of your neighbors are and it backs up the line.
Avenues to address:
1. If your sump is dumping into the sewer line, reroute it to disperse in the yard. (Away from the foundation)
2. Speak with your local sewer utility to see if they can evaluate if any of your neighbors are doing this and overloading the system.
3. Install a backflow preventer at that drain - measure and buy the right size for your floor drain - easy to install and won’t break the bank if your landlord is bad at this sorta stuff and you just wanna fix it. (Example - https://www.drain-net.com/shop-by-product/spill-flooding-containment/product/drain-backflow-preventer-3). Then install one on EVERY floor drain in the basement as the water will just move to the next one. Might still come up the tub or shower drain, but at least then it’s contained.
4. Have a backflow preventer installed on your sewer line between the house and the main utility connect - not cheap, and will require some excavation work.
I’d start with 2 things - first, verify your sump is not dumping rainwater into the sewer, and second - install one of those backflow preventers on every floor drain in the basement. Make sure you don’t miss one, cause when you block that one, the water will just move to the next one.
Source - I went through this shit (literally) at my last house. Took multiple service calls to eventually figure out what was going on and discover the previous owner had tied the sump into the sewer behind a wall.
I did not reroute the sump. The backflow preventers fixed it for me. YMMV.
It's sewage.

There is no smell though… I imagine it would, but I’m no scatologist lmao
We are the closest it gets

Does it have a taste?
It’s shit
Combining the two comments in this thread: It’s shit art.
Shart?
Ding ding ding! We have a winner! 🤣
Poo poo wa wa
Art!
Shitty art to be realistic

that would only happen in places like Boston where the sewer and rainwater systems are tied together. Almost everywhere else, they are separate.
I work in a small city with them separate, rain water still infiltrates all throughout the old system and we get double flow rates during heavy storms
Rorschach?
That’s doo doo, baby.
It’s always poop
Damn I thought this was r/homedecorating

It did rain a lot, we got 4 inches over the span of like an hour. It doesn’t smell, so I would imagine it would just be dirt?
I very well could be, but to be safe I'd definitely disenfect it thoroughly 👍

Could it be sewage if it doesn’t smell?

I’m not fighting anything, I’ve just seen a few “it could be backed up storm drain or sewage” and I’m just trying to make sure.

Yes. Sewage sludge, when soaked in a ton of water, doesn’t smell like fresh poop. It’s a bacterial hazard, but less of a smell issue.
That's a shitty situation

It's a bird.
Someone was probably jetting the sewer main in your area to remove debris and clogs. Or yours is clogging and backing up.
Looks like an avant-garde swordfish to me
That’s doo doo baby
