Here's my quick attempt to recreate a panaeolus cyanescens mushroom (found in many cow pastures in Hawaii). They're also known as "blue meanies" because like all magic mushrooms they contain a dark blue substance (psilocybin) that runs throughout the entire mushroom and becomes visible on the surface when you pinch it. This mushroom has a tan spot on the top of the cap, as shown, but I did have difficulty with the gills on the under side of the cap. I'm not sure if there's a better way to do it in sculptgl, but i just used crease and pinch for the radial lines, and then painted over it. cheers, - PR
