TYB Saison/Brett blend pellicle

[pbntoast]

Went to check my first sour beer tonight, and noticed a second 'layer' (?) of stuff about 1cm (1/2 inch) below the pellicle. It looks a lot like algae. I'm sure it's not, and I'm not worried, just wondering if anyone has seen this before.

Golden sour recipe, TYB Saison/Brett blend with Wicked Weed Serenity bottle dregs (I believe this is Brett only).

I have something like this going on with a sour starter that im stepping up from a bottle of Hanssens Gueze. Kind of like an algae looking thing floating around the top. Looks a little creepy, but it tastes great.
