I discovered a fungus /mushroom like pest growing off of my Taiwanese Trident plant that's been field growing for quite sometimes now.     I am worried this is parasite is not a good news, and I need to do something about it.  I might be wrong and this might turns out to be some sort of Ecto Mycorrhizal fungus which would establish some sort of symbiotic relationship with the plant, but highly unlikely ... I need to investigate and fast!
