Intentionally shading mushrooms

[ptreef]

I have some orange mushrooms (ricordia?) that seem to be spreading and stinging a hammer colony. Would there be any negative consequences to just placing a rock over them to essentially kill them?

Where are you located? I bet someone would take em off your hands

Unfortunately they’re mostly on a bottom base rock and I can’t remove them

Shading them won’t work. They will literally split or move to get back into the light (at least, in my experience, rhodactis and Discosoma will do this). I don’t believe rhodactis actually “stings,” but I think they are actually using some type of chemical warfare. I had a problem with rhodactis doing this to a large toadstool. Unfortunately I think the only solution would be trying to find a way to move one of the corals... the hammer may be easier, but eventually the mushrooms will grow into the next coral...
