[1] In 1880, the Lennox Association Football Club was founded, playing on Clapham Common.

[2] At the end of the 1883–84 season, the two clubs merged, and took on the name Dulwich, playing at the Mosquitoes' home ground and using the same pub for its facilities.

The Football Association ordered a replay, for which Dulwich refused to turn up, so Reading kicked off, scored a goal, and claimed the tie.

In 1888-89, qualifying rounds were introduced, and the club lost 13–0 to London Caledonians in their first tie.

The club played in white and dark blue, which were similar to the last colours of Mosquitoes.
