Terrestrial Cyanobacteria (Nostoc commune)

This strange patch of very dark green jelly-like shapes reminded me of the fungus Tremella.
The shapes were approximately the same size.Embedded in a suburban lawn in soil very poor in nutrients. The area was covered in many other mosses, lichens and tiny fungi.
It was a pleasant surprise to find this is not a fungus at all but something entirely different.
Common names include star jelly, witch's butter, mare's eggs, fah-tsai and facai.
