Field Notes

Description:

An alien-looking but edible cyanobacteria (relative of Nostoc flaggeliforme, or facai, a delicacy in the region of China where I lived for a while) that grows in dense soil, like the clay mixture where I found it. Wet, it looks like a mass of deflated balloons. Dried out, it becomes a thin dark crust that isn't dead but dormant.

Habitat:

Growing in our front yard, in a sandy clay soil type. Spotted after rain.

Notes:

Lots of fun nicknames for this one: star jelly, witch's butter, mare's eggs, soil algae (though not a true algae).

Hi Laura, a couple of years ago, I found this black stuff growing all over an abandoned courtyard of a church in Mexico. It looks like petroleum from a distance but is something live and was dry to touch. Really yucky looking. I was thinking some kind of fungus at the time, could it also be a cyanobacteria? http://www.projectnoah.org/spottings/15567225/fullscreen.
Do you know if this is one as well? http://www.projectnoah.org/spottings/292506002
