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 -

  • That definitely looks suspicious to me. I've never seen anything like that. I don't want to say anything for certain just from a picture, but if I saw something like that in my fermenter, my first thought would that it's gone bad. – Dronir May 8 '20 at 12:07

    How did you sanitize your equipment? – Dronir May 8 '20 at 12:07
  • Taste it or smell it. Looks might not be a good guide – Michael May 8 '20 at 23:37

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.

Google Images : mycelium fungus

As with all unknown fungi/mushrooms - until you know exactly what it is, I would recommend caution.
