Asterella
liverwort
General: Asterella is a liverwort, a type of simple, nonvascular plant, akin to mosses. Like mosses, liverworts are restricted to moist habitats.
CSUCI: Astrella is found widely around CSUCI, but only in well-shaded habitats (such as the shadiest parts of north facing slopes). It is active (green) only in the days or weeks immediately following rainfall. When dry and inactive, it is black and crusty.
