Cure poison quest bugged ?

Hey, is this quest bugged on the server (outland) ?

I have to get 12 lunar Fungus but i can't clic the mushrooms in the caves, if someone have more informations, please tell me.

For anyone seeing this in the future.

1. It is not bugged ( you can use herbalism to find them on the minimap)
2. You get the next remove / cure poison spell which removes 1 poison and ticks constantly anyway a few levels later.
