Resumen:
Optimum incubation temperatures for spawn production in 15 naturally occurring species (46 strains) of Agaricus, collected in Argentina, were determined. Wild strains were grown in Nobles' medium at 20°, 25° and 30°C, being the optimum growth between 25° and 30°C. While optimum growth temperature was fairly constant within a species, growth rates on agar plates varied considerably in strains of the same species. Optimum colonization period was studied considering the time required for a mycelium to colonize completely sterile wheat grains at the appropriate temperature. All strains grew well on this medium, and accordingly conventional methods of spawn preparation may be used with good results. Wheat grains were colonized in 15-30 days; a large proportion of strains tested (53.2%) required 20 days for full colonization. Future studies include fruiting tests in compost.
