There are some jelly fungi that look like the first picture, including transparent ones.
Normally, these primitive "jelly-like" fungus would be more yellow-like or even milky-clouded in their apperance. I agree, that such things are difficult to conclude with 100% certanity, but I still stand by my original explanation.
However, if the photos could be posted in higher resolution, including real close-op photos, it might help in order to achieve greater certanity.
As far as I know, the three most common "jelly-like" fungi are the Tremella Mesenterica (former known as lutescens) , the Myxarium Nucleatum and the Exidia Thuretiana.
Judging from the pictures the phenomenon in picture 1 exhibit a greater degree of actual transparence than I would expect from any of the fungi.
