I've just started getting this in my greenhouse. I reckon from a batch
of bad compost.

It spreads like wildfire.

What is it ??

More importantly how do I get rid of it ??

It's a liverwort. Looks as if you have been keeping the soil too wet.
It won't actively damage your other plants, so wait until you think it's
getting a bit too overwhelming for whatever else is in the pot then just
remove it and put a bit of fresh compost in its place.

I doubt very much the compost is to blame. The spores are everywhere,
they just need a damp environment to grow.

It sounds like vinegar (5% acetic acid) might do the trick ???

But keeping the soil dry and airy is going to be hard to achieve.

~~~~~~~~~~~~~~~~~~
This liverwort should not be difficult to remove. It is a gametophyte and
thus has no roots. This particular genus tends to be reluctant to produce a
sporophyte and hence no spores. It does however asexually produce very many
gemmae in the moon shaped [thus its specific name] cups which are dispersed
by water drops.
Peel them off if you wish~~ they do no harm.
Best Wishes Brian.
