Op, ok I somehow got over here from a beer forum. Sorry about the confusion. Clearly that is a mother. But Brosef is right, it does look like an alien...
My base is republic of tea pomegranate green tea.i think that is brown not green but w this funky purple base it's hard to say lol. Kinda looks green. Maybe I should get a close up photo w a flashlight? It doesn't appear to be growing on top of the SCOBY. But I can't say for sure.
The color of the base comes over as dark pom colored when I look at it, that is what threw me re: kombucha primary ferment.
Mold looks like mold, fuzzy stuff, any color. But the yeast threads in the base attached to the scoby are quite normal and actually will drop to bottom of container also. I just drink them.
