Abstract
Starting from string field theory for 2D gravity coupled to c = 1 matt er we analyze the off-shell tree amplitudes of discrete states. The am plitudes exhibit the pole structure and we use the off-shell calculus to extract the residues and prove that only the residues are constrain ed by the Ward identities. The residues generate a simple effective ac tion.
