From http://www.aquaticscape.com/articles/algae.htm:

"Brown algae

Forms in soft brown clumpy patches. In the freshwater aquarium, these are usually diatoms. Usually indicates a lack of light or an excess of silicates. Increased light levels will usually make it disappear. Easily removed by wiping the glass or siphon vacuuming the affected area."

Do you have Otos in your tank? They will eat this algae too.
