I see these occasionally on wet mushrooms of various species. Someone on this site will probably ID the culprit at least to group, bacterial/fungal or ?

Collecting very wet mushrooms is not advised and soaking any gilled mushroom in water is not good either. They get soggy! In this case, putting wet mushrooms out at room temperature is a great opportunity for molds and bacteria.
