I believe it is grapevine ?
Usually, you want to purchase this 'sand blasted'.
It's not great for setting on the substrate as it will not do well in a higher humidity.
You might consider replacing it w/ ghostwood ? at some point. However the ghostwood is not shaped this way and usually has to be sanded a bit to get rid of the "pointy" areas.

I read your other post regarding the fungus. It will stop , eventually. You could simply wipe it off...if it bothers you.
As mentioned...get some springtails in there ( Josh's Frogs - has great cultures --- good price and always producing nicely)
