Study in Cyanobacteria

It was green and ..snotty, but a little more solid. Like someone coughed up some strange phlegmy goo and it got rained on for a while. I didn’t see it, but I think others had mentioned that there was more hidden amidst the grasses, limestone shale and small forbs.
This goo has had many names, including Star Jelly, Star Shot, and Star Slime, Troll’s Butter, Witch’s Butter (not the fungi), and Witch’s Jelly. It is more formally known as Nostoc, which is the genus name of this really interesting cyanobacteria.
