This has been growing on my drift wood. I rubbed it off a week or so ago and now it is coming back. Any ideas of what it is? I checked AI but didn't get an ID. I do notice that the shrimp and other fish don't really mess with it. Would welcome any insights. Thanks!

  1. That’s a fungus, some kind of Xylaria species. Harmless as far as I know. I think there was a scientist on the sub actually researching it and asking people to reach out to them so they can get samples or something. I’ll see if I can find their info.

  2. I am in PNW. And will consider sharing it with you…you can message me more details, meanwhile I will research further…
