Stinky Fungus Take Over

Hey everyone! Ive been gardening in this bed for awhile now and been trying to amend the soil with compost, wood chips, yard waste, & anything but fertilizer. Unfortunately this season things were struggling in this bed such as the brussel sprout which took on no size, tomatoes which all produced fruit once then died, and even the arugula is having trouble growing. Everything except the bittter melon, which suddenly took off just a month ago and the green onions on the perimeter of the bed. Then for the last month, these fungus (theyre orange in the picture & has brown slime on them) has been popping up everywhere nonstop. I saw a one or two mid summer, but now theyre taking over the garden bed. If i dig into the bed, there are white nodules that i assume is a fungus network. Just need help understanding whats happening and if this is a net positive for the bed eventually. Im trying to respect the process and let things happen as it does without adding external fertilizer, but please share recommendations on any amendments you can tell i need!
