I used only DME and hops to boil the wort. Added dry yeast directly. I looked up on the internet for similar pictures but couldn't find any. I know every beer ferments differently. So I thought I better ask before I dump it. Any help is highly appreciated. This is what it looks like -
This looks like Pediococcus contamination: see here Is this lactobacillus?

Lack of sanitation might have cause this.
I'm not at all experienced with brewing ... but I have some pretty good experience with spawning and cultivating mushrooms.
That sure looks like a fungal growth to me. Classic mycelium threads, building into a network.
Some Google Images for you that look pretty similar.
As with all unknown fungi/mushrooms - until you know exactly what it is, I would recommend caution.
