We build on a recent photometric decomposition analysis of 7506 Galaxy andMass Assembly (GAMA) survey galaxies to derive stellar mass function fits toindividual spheroid and disk component populations down to a lower mass limitof log(M_*/M_sun)= 8. We find that the spheroid/disk mass distributions forindividual galaxy morphological types are well described by single Schechterfunction forms. We derive estimates of the total stellar mass densities inspheroids (rho_spheroid = 1.24+/-0.49 * 10^8 M_sun Mpc^-3 h_0.7) and disks(rho_disk = 1.20+/-0.45 * 10^8 M_sun Mpc^-3 h_0.7), which translates toapproximately 50% of the local stellar mass density in spheroids and 48% indisks. The remaining stellar mass is found in the dwarf "little blue spheroid"class, which is not obviously similar in structure to either classical spheroidor disk populations. We also examine the variation of component mass ratiosacross galaxy mass and group halo mass regimes, finding the transition fromspheroid to disk mass dominance occurs near galaxy stellar mass ~10^11 M_sunand group halo mass ~10^12.5 M_sun/h. We further quantify the variation inspheroid-to-total mass ratio with group halo mass for central and satellitepopulations as well as the radial variation of this ratio within groups.
