I got a piece of LR yesterday that had mushrooms on it. I have identified several things on it including serpent stars, fan worms, etc. but there are these little strands of what look like fiber optic filaments sticking out of it. There is no way for me to get my camera to zoom in on them at the right angle to see them and that is the only way I can think to describe them. Them are about a centimeter long and change colors at different angles. Anyone have a guess???? I am lost!
