I thought I'd found a small, but perfectly formed, lump of black pearl slime mould just outside our back door. Each "sporangium" was about 2mm across and looked perfectly black. Subsequently, I found two other lumps in a direct line to the pond...
As an experiment, I scraped up a very sticky lump and dropped it into a bucket of water. Within half an hour, it was expanding and showing transparent albumen and central black nuclei. Frog's eggs... Somebody couldn't wait!
