at least two lichens pictures here; would love help identifying both
hearty mat-like perennial clover on forest floor
very small, low-growing manzanita - compare to car keys in second picture
fairly large (about 8" wide) muchroom growing on the base of an oak tree; top and underside of mushroom pictures
i think this is an iris of some kind; about 8 inches from from side to side here; possibly a grass?
