Carbon sources viz., glucose, fructose, sucrose, mannitol and sorbitol; Nitrogen sources viz., ammonium nitrate, sodium nitrate, potassium nitrate, glycine and calcium nitrate were supplemented in Czapek’s dox medium to study their influence on chlamydospores production of Volvariella. Supplementation of sucrose and potassium nitrate to the growth medium each at 3 per cent level encouraged the mycelial growth and chlamydospores production of both V. volvacea strain CBE TNAU 1505 and V. bombycina strain CBE TNAU 1406.
