Some kind of white mold is infesting several of my plants, below is one of the worst infections of a tomato seedling. It is very aggressive, if I remove the top layer of soil it will come back in a single day. It has infected some basil seedlings as well.
It is mostly white, but forms slightly yellow centers in some places, as can be seen from the picture.
Can you identify what it is? And how do I get rid of it?
