Saw it at my lfs. Has anyone seeing it before with this kind of coloration?
Was it bleached?
Just a guess, but my guess would be insufficient light. I have a bunch of green hairy mushrooms. One of my corals grew so large it blocked their light source for several weeks. They then turned clear, but since I moved them I slowly see their color coming back.
