Until recently I'd never brewed with anything other than commercial Sacc strains, so I really have no idea what various yeast strains and bugs look like during various phases of fermentation. From what I gather, due to the blended nature of most lambic/sour brewing, it's difficult to determine which microbe is causing various qualities in the pellicle and whatnot. However, I figured it couldn't hurt to ask.
I posted a picture of this in the pellicle picture thread, but the point of that was to share, rather than seek input. I collected this yeast from dates, and I'm pretty sure it is a single species of yeast, since I streaked it on an agar plate and selected an isolated colony. However, I have no idea if it's Brett, Sacc, Zygosacc, etc., since I have no microscope or anything like that. I thought it might be Sacc at first, because it had a krausen that looked a lot like sacc, but now it's developing a pellicle (a little over a month in primary), so I'm wondering if maybe it's brett? The hydro sample I tasted about a week ago was definitely vaguely "earthy," but not overwhelmingly so, and not "funky" or "cherry pie" at all.
Here are pictures, first the krausen (a few days after pitching), then the pellicle forming (about a month after pitching):
