Abstract The growth of granular, velvety and cottony strains ofT. mentagrophytes on Sabouraud's cycloheximide, chloramphenicol agar (SCCA) and brain heart infusion agar (BHIA) containing varying concentrations of NaCl showed that as the concentration of NaCl increased above 3 % the growth decreased. On SCCA with NaCl some cottony strains became velvety and some velvety became granular. On BHIA containing NaCl the aerial growth of many strains became glabrous, wrinkled and darkened. The most satisfactory concentrations of NaCl in SCCA that promoted the formation of macroconidia were 3 and 5 %. In BHIA the production of macroconidia was not influenced by NaCl. On SCCA containing 3 % or more of NaCl the morphology of microconidia was usually sub-spherical.
