I see far too much rotten stuff at my workplace.
Turquoise-grey powder on the ground turns to this ugly, chalky fluff, and from that, there looms the spire. Running on the ground here is not the best of ideas, all that powdery substance being spores or choked with spores.
I should draw the picture that’s in my head but for now, I kind of imagined a big wiry spike looking thing completely covered in shelf-shaped bits, like this! Mushrooms growing on mushrooms, less cutesy, more like a horrible mess of layers all clambered atop one another.
