Thus, if you have a mushroom out on the edges that doesn't have 4 others within that area, it can then place a mushroom in an area that already contains 5 or more.
I went through the code myself for it when mushrooms became relevant as I was finding the growth parameters rather unintuitive, and found the wiki to be rather sparse on actual info.
I *may* do a revision pass on mushroom growth at some point, as yeah, it's rather whacked as a system. It was just never really relevant before HC Hunger.
