"Mold" is a slimy fungus, that is often green. I have no idea how "warp" works with that.

Can anybody help me with the word mold-warp in the context below? I have found the word means a mole but it makes no sense in the sentence ...
"Behind me and in every shadow seemd spreading like a pool of viscous fluid the green and brown and gray of fungus, of mold-warp and rot."
Leonard Cline, The Dark Chamber, 1927
"Mold-warp" meaning "earth-thrower" is an old English name for a mole. It's hard to see what exactly the author means by it.
Could it be the word mold-warp has nothing to do with a mole but means, in the story context, a spot on the floor that is so infected with the mold (mould/rot/fungus) that it is physically warped (blistered/bulging)? And the author used the old-fashioned mold-warp because the bulging surface of the floor reminds him of mole-heaps?
It could be that I suppose.
It seems the most likely explanation, and this is not the first time your author has come up with something idiosyncratic and strange.
