Ferntasia

These are some photos I took the other day about 150 meters from my house. Actually, I'm beginning to expect that these aren't ferns, but I like the title, so... I would love for someone to identify them for me.

This one almost comes out of the screen at you.

Did you know that lichen is symbiotic controlled parasitism? I learned that the other day.

See all those little circles on the leaves?

What the heck are those? Part of the plant or some sort of fungal parasite? Did you notice them in the first picture above?

Vertical depth of field vine.

After the photo above, I figured I should give you an in-focus shot of this beautiful crumbling mansion. I'm not a construction expert, but I suspect this house is not salvageable.

Are these berries?

I feel so ignorant...
