Abstract Eleven specimens of different indigenous Agaricus species were collected during rainy season of year 2008. Out of them, 8 species of Agaricus viz., Agaricus semotus, Agaricus augustus, Agaricus trisulphuratus, Agaricus arvensis, Agaricus bernardii, Agaricus macrosporus, Agaricus bisporus and Agaricus bitorquis were identified on the basis of fruit body morphology, macro as well as microscopic characters and chemical tests. Out of these, Agaricus semotus, Agaricus augustus, Agaricus trisulphuratus and Agaricus macrosporus are reported for the first time from Rajasthan, India. Five single spore isolates (SSIs) of Agaricus bisporus viz., 21 H, 23 H and 27 H showed appressed growth whereas SSIs 39 H and 41 H showed fluffy mycelial growth with zonation. Further, sectoring was not observed in any of the SSIs tested. The temperature range 20-25°C with optimum temperature 25°C was found best for all the strains tested for their mycelial growth, whereas strain IA3 showed good mycelial growth at 35°C temperature also. Further, strain IA2, IA5 and IA9 gave no mycelial growth at 35°C temperature. Pigments and exudates formation was not seen at any of the temperature and strains tested. The strains IA1, IA2, IA3 and IA4 were found compatible (100 per cent) with all the strains tested, except strain IA2 with strain IA5. Out of 9 new hybrid cultures, 4 hybrid cultures (IA2 × IA3, IA2 × IA4, IA3 × IA4 and IA3 × IA5) showed appressed growth, whereas 5 hybrid cultures (IA1 × IA2, IA1 × IA3, IA1 × IA4, IA1 × IA5 and IA4 × IA5) showed fluffy mycelial growth, 4 hybrid cultures (IA1 × IA3, IA2 × IA3, IA2 × IA4 and IA4 × IA5) showed zonation at periphery, whereas only 3 hybrid cultures (IA1 × IA3, IA1 × IA5 and IA2 × IA4) showed sectoring. Development of pigment and exudates were not observed in any of the hybrid culture tested.
