There’s a fungus among us they say!!!!  Is your lawn starting look dead or thin?  This time of the year chance are you have root rot.  It is a fungus that can take over the grass and kill everything.  the good news is it can be stopped pretty easy.  Don’t ignore it though, it needs to be addressed pretty quick.  The bad thing about all fungus is you can’t effectively prevent fungus, only treat it.  It tends to happen in areas that are very wet and the roots start to rot away.  The area will not look like your typical fungus though and most people do not think about fungus when they see it.  Fertilizer is what most people resort to in a effort to make the grass grow.  This is actually a negative in some cases.  Do your grass a favor and get it treated with a quality fungicide ASAP!
