what is this tree fungus?

Asked August 4, 2016, 10:53 AM EDT

This whitish-yellowish fungus has appeared at the base of an oak tree in my yard. It was not visible a month ago. Can you tell me what it is and whether it can be treated?

Thanks,

Kate

It appears to be white slime mold. It should have disappeared by this time, if not, please send me another photo. It would not need any treatment.
