Cedar-Apple Rust Galls (Gymnosporangium juniperi-virginianae) - The Great Swamp National Wildlife Refuge, New Jersey
Nothing like a little rain to bring out the Jelly-Rats.
Actually these orange slimies are trapped inside The Cedar-Apple Rust Galls all winter and when the Spring rains soften the exit holes the telial horns are extruded. The galls don't harm the cedar, but the spores emitted by these slimmy orange tendrils cause a leaf rust that is harmfull to apple trees. And amazingly enough, this happens just as the Apple leaves are sprouting from their buds!
