I have 2 trays of chilli seedlings, in both trays I seem to have begun to grow lots of very small mushrooms however on closer inspection on the seeds that diddnt take I have found hundreds if not thousands on two of the seeds of these yellow spores and in the soil surrounding them, they look like very very small mushrooms talking less than a millimetre big each with a yellowish colour, I removed the top layer of soil to check weather they were still growing and if I needed to remove the rest of the seedlings yet ect and there they were, they have affected so far (to my knowledge) two different seeds in different parts of one of my trays however the mushrooms are growing all over both of my trays, do I need to be concerned for the health of my seedlings that have sprouted already, what should I do?
