The pine bark I had molded in the bag, I could see fungus too.
I can't compots here because the place is not suitable. Our city is collecting green from citizen, they placed big open composters here an there on the territory. So I thought I could call someone (the municipality, I thought for sure) and ask to give me some of the compost I contribute to make. Until now it's impossible to know a phone number or having a name to contact.
