What's this on my driftwood?

[bamboo]

I've been noticing white oval shape things on my driftwood and also bristle like needles on my driftwood as well. I removed one of the white oval things and it leaves a white mark behind.
I've got green fire tetras, cardinals, bristlenose plecos, american flagfish and zebra nerite snails.

"Bristle-like needle stuff on the driftwood"...Black brush algae? Need some pics to determine what it actually are.

If they're nerite snail eggs, How long does it take to hatch cuz its been there for over 2-3 weeks now.

[Momobobo]

They hatch in brackish/salt water only.

I'm not an expert, but a quick google search tells me that the eggs don't usually hatch in freshwater well and that the eggs may not hatch and left as it was laid. There are tons of info about breeding nerite snails and the annoying unhatched white eggs they leave behind.
