White powder on soil this morning

Does anyone know what this white powder is that appeared on my organic soil in our garden bed over night? Is it good or bas? Should I do something with it?

 

Maybe pollen? Was it raining in the night?

 

No rain. It is all over the soil in one bed and not the other.

 

It could be a slime mold, but it's hard to tell without a closeup.

 

Agree with @vitog - a closer shot would be helpful to see if this is a slime mold or a fungal mold

 

When I scooped off the top later of soil it was on it was powdery and floated through the air so it is more powder than liquid/wet. I have taken another picture of it.

 

I often used to find a white fungal film like that on my soil though not for the past few years. It didn't ever seem to do any harm.

 

Good to know! Thank you!!
