Any idea what this is? I thought it was like a cyanoco at first so went to remove it and it didn't lift away. Scraped a little harder and it sliced open like a sponge ?? Took no time for it to grow over the sliced part. I don't mind it except that it keeps killing my leather and I would much rather have it. Thanks for any advice.
