Some kind of fungi in tomato soil?
First of all sorry if this is in the wrong forum, this is my first post here. I wasn't sure if this should be in the forum for identification of plants, or in this forum, but I figured that since it's related to a tomato plant, and may be some kind of disease, the post belongs here.
Ok so anyways, I've got this (some kind of fungi?) growing in the soil of one of my tomato plants (container) and was wondering if anyone knows what it is, and if it can be a problem?
Picture attached is of the fungi(?)
Thanks in advance ;)
