This is a myxomycete (or slime mould) part way through the transition from the mobile (or plasmodial) stage to the stationary, sporing stage. In the plasmodial stage a myxomycete has no definite form. Here you see the beginnings of the development of numerous small, ball-like bodies. Eventually each would become a small ball, consisting of a very thin, brittle case within which there is a mass of powdery spores. You can get the idea of the changes from this photo (http://www.cpbr.gov.au/fungi/images-captions/leocarpus-fragilus-0311.html) where you see some plasmodium (like soft butter), an intermediate stage (yellow balls) and numerous mature spore capsules (dark brown). That gives the idea but yours is different (a white/creamy plasmodium). I did once see something like this that, at maturity, turned out to be a species of Physarum. However, plasmodial colour alone carries little information, so while you might also have a species of that genus, I can't be sure from the photo.

Thanks Heino, is it worth me going back in a week, two weeks or so to photograph the slime mould at maturity?

The time of maturity is hard to predict. It may already have happened. Once mature, the brittle cases can break easily and you may find little, if anything, left. If you happen to be going there, it won't hurt to look, but go with a pessimistic mind! Note that it might still not be identifiable from a photo.

Thanks Heino will have a look this weekend as a natural born optimist
