Help pest ID on Toadstool leather

[brucelee90]

Hi guys, I just noticed these little dark brown rings on the tentacles of my toadstool leather, spreading from one green toadstool leather to another. Is this normal? I'm not sure if it's algae (diatom) or some kind of pest. Thanks!

Doesn’t resemble a pest to me…is it possible that it just came out of a shed and some got “stuck”?

I was thinking the same thing.
