What makes C Lydian Augmented different

Lydian augmented is Lydian with a raised fifth, and that ♯5 is the one note separating the two. It's the third mode of melodic minor. Without a perfect fifth its tonic chord is an augmented triad, so the scale fits a maj7♯5 chord. Its first five notes are the same as the whole-tone scale's; only the top of the scale, 6 and 7, breaks the pattern of whole steps. On C, C Lydian Augmented has G♯ where C Lydian has G; every other note is shared with C Lydian (C D E F♯ G A B).
