I would suspect that if you removed these, they were brown at the base, indicating a dying leaf. This algae frequents my 90g and always on dying leaves.
What is your fertilization routine (brand and frequency)?
I use flourish comprehensive, the day after my water change and a few days after. The tank size is only 6.5 UK gallons, so I don't use a lot and plus I'm not too sure how much I am supposed to use for a tank that small lol
