I have the exact thing you're describing all over my moss...I've been trying to figure out what it is too. It's not clado or spyrogira. It most closely resembles rhizoclonium but like yours mine does not feel slimy. When I remove it it feels like nothing at all. My tank is also cleaned once a week with 40% water changes/algae removal and dosing ferts. It's certainly not from poor maintenance. I don't mean to hijack your thread but I'd LOVE to find out what this stuff is so I can get rid of it...
Good luck with your tank. If I find out what it is and how to kill it I will be sure to pass it along!
