The second lichen I found:

ID:Xanthoria parietina or yellow scale

Third lichen; possibly same type as 2nd, not sure:

ID: ???

Fourth lichen:

ID: Parmotrema perlatum, or black stone flower

Fifth lichen:

This lichen was a fruticose lichen. and about an inch tall. It has little branches coming out of it and is a pale green/white color. It tends to grow in patched clumps like this one on branches. This was found on an apple? tree I believe.

ID: Evernia prunastri, or oakmoss.

Sixth lichen:

This foliose lichen is a white color and spreads itself in large, round patches on tree trunks. They edges are irregular and look like snowflake edges. Seems to be made of little flakes sort of overlapping or built on top of each other; they are stiff and do not yield to a light touch. Diameter is about 3-5 inches. This was found on a bush (picture below)

ID: Parmelia , Shield lichen
