Is this mold or just rotting wood?? Help please :)

[KKess]

I have three large branches in my chameleon's cage, two are from either Exo Terra or Flukers ( I can't remember which brand I went with) and one is from a local reptile shop. They have been in my chams cage since December. I noticed only one one of them ( and I can't remember if it is one I bought from the local shop or eco terra/fluckers) has areas that are black. One area is almost pitch black, and the others are a litttle lighter but seem to be localized to one common area. I am worried it is black mold, or any kind of mold. However I do not think it has the typical appearance or the fuzzy texture like mold tends to get. It may just be rotting wood. Can anyone help if you know what this is... see pics... thanks !

Have you tried to wipe or scrub the area? If so what happened when you did? In my experience encountering mold, most mold will wipe off or scrub off fairly easily. If you tired that and the wood itself seemed to splinter I would say probably the wood is no longer stable and should probably be replaced. I am no expert though!
