It's a good thing for this species that it isn't a bit browner & duller - it would get stomped on by disappointed morel hunters.
Several years ago my good friend, who shall remain nameless, told me that he had once seen a slimy salamander in Fern Hollow in Frick Park. After a few years of looking but never finding one, I asked him exactly where he saw it... and he had no memory of ever seeing one there.
I can't explain why I was looking for slimy salamanders at dusk in a rainstorm, but I was, and I found one.
