Help! What is this gross yellow foamy/spongy stuff?
This morning when I left my house and was getting in my car, I looked at my front garden and noticed this really disgusting looking yellow foamy/spongy stuff in two spots in my garden---around the trunk of a redbud and underneath a mum. The two spots are a few feet away from each other, and there was none of this stuff in between or anywhere else in the garden (at least that I saw in my frenzy to get to work). I used a trowel to scoop it away. It's a very spongy/foamy substance that is a strong yellow in color. Does anybody have any idea what this is or what I should do about it? (I don't know if it makes any difference but it has been very humid here and we had strong thunderstorms last night so it was very wet this morning. But I haven't seen this stuff before and I didn't see it in any of my neighbors' gardens.) Thanks for any help!
