will this fungi threaten a giant eucalyptus? It is a very masive and proud eucalyptus that I enjoy looking at whenever I go to this park but recently I notice there is a fungus that spawns mushrooms from nearly all edges of the soil at the base of the trunk. I'm fairly worried that this little fungus will meet the demise of the giant eucalyptus.. Anything I can do to kill the fungus off without telling the county parks and stuff? they basically let everything go to rot here, even the old rental buildings that used to have nice picnic areas are rotting away, it was a nice place down by the water with a deck. now its a rotting shed... I'm not about to let that happen to the tree.
