Weeds?

[Spool]

Hi everyone,

When building my garden bed for vegetables, I placed wet cardboard at the very bottom; about 12inches deep to kill the weeds below.

2 weeks later, I'm noticing these seemingly dead, grey in color, tiny leaves surfacing through-out the soil.
Are they in fact, weeds?

Should I just pull them and be on with it?

No, not weeds. Fungi. It is beneficial and is growing from the dead organic matter it's in.

Great! Thank you Chuck.
Do you happen to know the name of this Fungi and what it's benefits are?

I don't think the pictures are clear and close enough to ID, but here's a website that helps in identifying mushrooms

Thank you so much everybody.
That database and article were very informative.

I believe the fungi I'm seeing is "Coprinopsis atramentaria"
Which I found on this page, and who's photo nearly matches mine identically.

They start out as tiny white mushrooms and after about 24hours appear to be dead/dried leaves.
I've uploaded better pictures here.
