Are these dead salamander eggs or something else?

[Spazmatism]

I have no experience with salamanders, but I thought it would be interesting to examine an egg mass that I found on top of a very moist wood pile covered with a tarp. It's just about mid-autumn here on the east coast US, so I'd think that any eggs that had been laid should have hatched by now, but I'm not sure. I didn't want to take eggs that were going to hatch.

On closer inspection, it looks like there are nematodes living in/eating the eggs. I looked in a microscope and I saw some protozoans moving around too.. Some of the eggs appear to be completely white inside, while others are clear but have no visible nucleus. I'm wondering if they could be slug eggs?
[this is a single egg:]

Are they salamander eggs? I wouldn't think that they are frog/toad eggs because all frog tadpoles need water. If they are salamander eggs, then they are dead, right? Why might they have not hatched after they where laid?

Lots of them aren't fertilized, and the few fertile are full of parasite worms :wacko:

They look like eggs to me, eggs that didn't develop. So they are probably being eaten by whatever, like those worms.

If you gently misted them with water can some eggs be saved?
