Default To pitch or not to pitch...mold is my question

Probably just being overly cautious, but would like some thoughts on whether the film on my starter is the beginning stages of a pellicle forming. Just made this starter on Tuesday night and noticed the film and slightly odd bubbles on the top this morning. Brewing tomorrow morning, so I have time to get new yeast, but probably not for a starter. Hoping this is nothing and still pitchable. Probably just worrying, but would rather not start off on the wrong foot.

The yeast is 3711 if that matters at all.

Anybody have any thoughts on this? Probably just worrying, but would rather not pitch a starter that's in the developing stages of mold growth.

It looks ok to me. How does it smell?

There's nothing wrong with that in my experience.

Smells like it should...yeasty!

My main concern was the chunks of film on the top. Kind of looks like the start of a pellicle forming like in wild fermentations. Figured it was probably nothing, but thought I'd get a second opinion.

If it doesn't continue to grow/get worse by pitching time tomorrow, it's going for a wort swim!

It's not mold. It may be a pellicule forming, or just a lot of yeast rafts, but it's not mold.

Sounds like I've confirmed that I indeed worry too much. Glad to hear that there's nothing wrong with the starter. Thanks everyone!

I don't do wilds, but I have never heard of a pellicle forming that quickly. Just yeast on the surface and surface tension.

I don't do wilds either, but hope to someday. I agree that the chances of a pellicle forming that quickly is probably pretty slim, but thought checking on here couldn't hurt. I've brewed for a while now, but frequently run across something that I've not encountered before.

Honestly I have done a lot of starters and none of them looked like that. Every starter I have done has had a clear top. How long has this been sitting? I'd hate to see a batch ruined by a bad starter.
