Hi damonbrunette,
Having come across C. leucocephalum several time I agree with you as this is the best guess with out doing the microscope work to key it out!

Some ideas..

Though there are Physarum, Didydium, and Crateritium that all appear on leaves like this… im leaning towards C. leucocephalum. Ive never seen this before myself, but after consulting Stephenson, Farr ‘How to know the true slime molds’ and a host of online pics, im inclined to go with this because of the calyculus present. Some also look like the peridium is tearing in a uniform equatorial pattern.
Now i know that the in picture you have bodies look mostly rotund, but in the back some appear to to be oval shaped as well.

http://slimemold.uark.edu/... This link, i dont think the visual images line up great, because your sporangia are not fully developed, but i like this website if you have not seen it.

Sporangia in the middle stages appear to look this way.

pin head myxos.
