Sap and ... what?

Spring is on the way, I guess, and I have photos to post ... when Blogger decides to stop being on a go-slow. So the gum trees are getting excited, and I keep finding little knobs of red sap on the ground. This is on a tree, though.
And this is ... mould? I think I've posted a similar photo a year or more ago, and someone suggested it was a type of mould or fungus, but this specimen wasn't in a damp area. It was sitting on the side of the track in the grass and leaves. It did look wet, though.
