If the lens was described as not having haze or fungus then you should file a claim and don't try to fix it yourself.
If it was "as-is" without much detail you may be stuck with it.

You know we could all help the OP a bit more if we could see the original listing. . . . . .

thanks everyone, I have claimed ebay and got shipping fees refunded!

I will send this to the seller later!

questions, What if the cost of shipping is more than what I got from seller? does ebay cover rest of them?

Typically, the seller sends you a return label, although it might be different if it's an international transaction. I imagine eBay won't force the seller to pay out any more than they charged in the first place.

You do not state where you are, this might help in this matter.
First of all the fungus you are looking at is caused by the last owner poring cleaning fluid (you should put the cleaner on a lint free cloth and then wipe the lens after carefully blowing of any dust or grit) on the open to air elements, this creeps around the element and collects on the reverse surface, soon small invisible mould starts to breed and the result is what you see, this did not occur in transit, your seller is pulling a fraud full stop.
The 35 f2 is a bit rare item so if you like the rest of the lens , Open a case in Ebay (is much better if you have paid by Paypal as they can charge back your payment up to 3 months after the transaction), In the U.K to clean out a simple m series lens with no electrics is straight forward and can be done for about 40 pounds, so negotiate a refund of about 45 pounds to cover your costs, or simple go for a total refund and get your money back, do not worry the seller stated no returns in the advert, Ebay will not let that stand for an item that is broken and not stated as such in the original advert.
As another option you could try a home fix as the front and rear element are easy to access on an M series lens.

First, just two posts up, the OP stated has already won the case.

Secondly, of all the ludicrous assertions I've seen about the causes of lens fungus on this forum over the years (e.g. fungus jumps from lens to lens!), this ranks right at the top.

The retaining rings used on even unsealed lenses are tight enough that for typical water/ammonia/alcohol based lens cleaners, capillary action is not strong enough to pull in any significant amount of liquid past the ring, and even if it were to, it would not get far after that. You'd literally have to dunk/soak the lens in the fluid to get enough pressure to get any kind of significant infiltration. This might be different if you used something petroleum based like lighter fluid which is much more penetrative and can carry hand oils, etc. into the lens, but even there, staining left behind when the fluid dries would be much more of an obvious problem than fungal growth.

This fungus is clearly on the surfaces adjacent the aperture. This is the most common place for fungus to form, since these surfaces are not enclosed by retaining rings. If it had crept around the elements like you said, you'd see the most fungus immediately behind the front element, which you do not. Furthermore, if liquid had managed to reach these surfaces, it undoubtedly would also have reached the spring steel aperture blades, causing them to rust fast together long before any fungus began to form.

In almost every case, fungus is caused by three simple factors: heat, darkness, and atmospheric humidity. These activate spores that are already latent on glass surfaces or are carried in by dust. Fungus needs very little food to survive (even completely uncoated glass can support it just through micro residues on the surface), and no standing water, as it draws its moisture from the air. Cleaning fluid is a complete red herring.

And yes, this could have occurred during transit if the item spent extended times in a box in very humid/hot areas. This amount developing in such a short time would definitely be an outlier, but it's not beyond the realm of possibility, especially if there were smaller, less visible colonies developing in the lens before it was shipped. Either way, per the eBay agreement, the seller is responsible, just as they would be if any other damage had occurred during transit.
