Is it possible to take apart Takumar 28/2.0?

I got this lens with a little bit of fungus inside, right behind the front element (as you can see on picture), but I don't see any screws or ledges which can be used to disassemble it. Any ideas?

The screws are underneath the ring with the name on it. You need a rubber ring to remove it.

Something like this

Micro-Tools Europe Tools | Lens Ring Tool Set | buy online

or this

There are other things you can use. As long as it has enough friction to grip the ring and won't damage the front element. Rubber washers, rubber bands...

Use a rear lens cap and a piece of rubber cut from an old rubber glove.

As a simple point of discussion NO it is not possible to take apart a tak 28/2.0. Why? Because it does not exist. You have a tak 28/3.5'

Taking it apart isn't the hard part...putting it back together is. This is the voice of experience speaking.

ha, I can imagine is it so hard that better leave fungus as it is and shoot it while there are no visible artifacts?

It will take you ten fold of time to get the lens back, often not as good shape, due to infinity adjustment, grease..
Better leave it to pro service. In most cases, the fungus wont affect image quality, just annoying.

Still want to open up? Get a set of real rubber tool to do the job. Then a set of quality JIT screw drivers. Dont lose any part.
Best wishes.

The Takumars I have taken apart have flat screw heads. Later lenses have JIT screws, but this may be a US thing...
