rather than scribble about it I should probably google it and figure out how to rid myself of it but my favorite thing about house plants is that they grow in surprising and new ways and they are alive! the fungus fulfills these qualities (though I am not sure whether scientists call it "living" - another thing to not google) so I'll watch and hope that the web's med doc wouldn't admonish me for keeping this yellow stuff breathing the same air as me it's alive! and I'd like to continue to be but I'll let this unfold as a surprise
