I have tried every link from this website, plus! This showed up about two weeks ago. It is growing on concrete in full sun. It is spanning a crack but not touching the ground. It is like a foam. It has orange or yellow goo oozing out like toothpaste. It is thick and dries almost like sap. It is up to two inches thick in some spots. It has no defined shape and is the same consistancy all the way through. There is no cap, stem, fin, legs or anything but the ooze coming out of the "foam". Please help !! I am very interested in knowing what this is. I have looked under lichen, mold and fungi. Thanks!
