I am trying to grow Lion's mane and Oysters, however, on a control plate, I saw what I think is black mold. I threw it out. Someone please tell me otherwise. This morning, it wasn't there, now it is.

They won't click a link to imgur? That's weird. Any reason why?
It's about trust. Clicking on external links poses a security risk. Also shroomery automatically removes exif medatadata embedded into pictures.

Dangerous would always be a massive spore load to your lungs, be it mold or not. So i wouldn´t open the plate, as there´s no need to. What´s your agar recipe? Looks very wet.

Looks like Rhizopus to me. It is a common contaminate.
I usually refer to it as pin mold.
I'm not sure how dangerous it is but I wouldn't open it.

It is just agar and light malt extract, maybe I put too much water, but I followed this recipe:
I did fuck up on the condensation big time. How would I avoid such condensation next time?

Pouring at a lower temp is how I control the condensation.
I start pouring at 120°f
I stack them with the hottest ones on the bottom and let them cool.

I usually pour the malt to room temp water and dissolve, after that the agar-agar, finally bring it to a short boil. Maybe you didn´t, and the agar-agar wasn´t fully dissolved and settled to the bottom of the media bottle.
For less condensation i leave mine placed in a ziplock in the SAB for ~a week after pouring, after inoculation in an insulated pizza box. Temp swings bring you that condensation.
And yeah, what Vibe said.

Another really bad thing is my agar plates are lumpy

Maybe pouring temps were even too low in your case, so the mixture started to harden already in the bottle. A infrared temp gun isn´t a bad investment to that hobby and not expensive.
If your hands are used to temps, you can rely on that, so if you can hold the bottle with your bare hands without burning yourself, it´s a good time to start pouring. But i always use my gun.

I bought one just now! I want to do everything I can do prevent contam, this is my reason for using agar in the first place. But, mistakes happens.
