Calocybe indica strain CI-3 was investigated for mycelial growth on solid as well as on liquid medium. Three media namely Complete Yeast extract Medium (CYM), Potato Dextrose Agar (PDA) and Wheat Extract Agar medium (WEA) were supplemented with three growth regulators Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA) and Gibberellic acid (GA) @ 10, 25 and 50 ppm each separately. The maximum colony diameter (mm) and growth rate (mm/day) was observed on WEA medium supplemented with IAA (10 ppm) on 5th and 7th day, IBA (10 ppm) on 5th day, IBA (25 ppm) on 7th day, GA (50 ppm) on 7th day and CYM supplemented with GA (50 ppm) on 5th and 7th day. The biomass growth was maximum in broth supplemented with GA for all the media with maximum (24.2 g/L) in complete yeast extract broth.
