Found this weird growth in my plant’s soil.
At first glance, I thought it was rosemary!

Yeah, definitely has the look of rosemary.

Looks like saprophytic fungi. Totally harmless! If you’re lucky, you might even get mushrooms popping up!
The spider egg comments are freaking me out, so I’m not sticking around to see mushrooms. 
@Morgan
Don’t worry! Mushrooms are actually really good for your soil.
You could take the rosemary out, shake off all the old soil, and repot it in fresh soil in a new pot. Clear plastic pots aren’t great for roots since they let light in, and roots don’t like light.

Thanks! I didn’t know that. I’ve always used clear pots because it’s easier to check the roots. I’ll switch to regular ones.
@Morgan
You could keep the clear pot but put it inside a decorative one. Makes watering easier too!
@Morgan
If it helps, I used to run a horticultural company, so I’ve dealt with this kind of stuff a lot.
That looks like flower pot fungus (sclerotium). It won’t harm your plant.
It might be some type of fungus.
Looks like you’ve got more than just herbs growing there!
I switched to coconut coir instead of soil for this reason. Soil always seemed to bring bugs or fungus.

Using wet-dry watering cycles can help avoid bugs, gnats, and fungus in the soil.
Nice.
Rosemary is pretty hardy. It should bounce back.
Looks like rosemary.
