Probably what's called diatoms, or commonly brown algae; very common in new tanks at some point during the first 2-3 months. It cleans off easily with a sponge scraper (on glass) or a small brush (decor), or your fingers (plant leaves, gently so as not to damage the leaves). If this occurs in established tanks (very rare), it may be due to insufficient light or an imbalance.
