What contaminant is that? Trichoderma?

I'm wondering what contaminant it is that my grow got killed from.

Judging from other pics I assume it is Trichoderma. But what confuses me is that it didn't turn green even after two weeks of showing up on the surface. Does it take that long to turn green or is this some other mold?
I decided to keep the tubs for a while to observe how it goes - out of "scientific" interest.

Looks like bacterial bruising

Did you just make that up?
When I google "bacterial bruising" site:shroomery.org I get no results.

I think it's some fungal contamination. Not really sure, wait for more knowledgeable people

I'm curious what sort of mycelium this is. If it's a mold it should change color at some point - or are there exceptions? The color change would correspond with the production and dissemination of spores.
Could it be B+ mycelium but somehow fucked up?

The fluffy puffed up look is why I call it bacterial, on top of having typical yellow bruising/metabolites associated with bacterial contamination.
Looking forward to the Correct answer

I should've added that the yellow areas are actually from the B+ mycelium. First it grew fine then it slowly withered away with those fluffy, super-white stuff growing all over it.
So, the questionable mycelium (or whatever it actually is) is perfectly white and looks like small cotton balls.
I know it's not a good idea but I took a whiff and the smell is not rotten, but also not exactly the typical B+ mushroomy smell but rather a bit on the chemical / tangy side - I'm not sure how to properly describe it and don't want to risk my health by taking another more extended whiff.
