Could be nothing but could also be the start of mold!! Maybe try repotting and hopefully it doesn’t come back! Hope that helps:)

Thank you. Do you know what causes it? Is it overwatering?

#### Ian Pittman🌿さんが2023-08-29に返信しました

Yes! The two most common causes are usually low light or overwatering, if your plant likes a lot of water but the dirt doesn’t then you could try switching pots to something more ventilated or with better drainage!

this looks more like mineral build up from hard water than mold, consider flushing the soil with distilled or rain water to rinse off the excess minerals

This may well be true, the water is very hard here.

It’s prob just fungi fungi is our freind it doesn’t do anything it just spawns on decomposing material such as soil especially when it’s moist very common on plants like your prayer plant because it likes moist soil nothing to worry about
