Wild mushrooms were collected close to cattle manure in pasture areas in Tamarana (Paraná/Brazil), with the objective of finding and domesticating new non-exploited basidiomycetes. An edible basidiomycete of the Agaricales order was classified as belonging to the Macrolepiota bonaerensis species (=Lepiota procera, form bonaerensis (Speg.) Rick or M. procera (Scop.:Fr) Sing.). The mycelia was isolated and characterized for growth rate in different culture media. A vigorous growth was observed in PDA Medium (pH 5, ±25°C). The oat culture medium was the most appropriate for cultivation submersed. M. bonaerensis mycelia secretes lipase, cellulase and protease exoenzyme types. Cytological analyses confirmed the bi-nucleated condition of the mycelia, the presence of septa and clamp connections in the hypha. The fructification occurred in the substrate composed of sterilized humus + soil (1:9) plus casing layer with active carbon.
