Valorisation of agricultural wastes is one of the main objectives for activity optimization in agriculture industry. One method for waste utilization implies their use as substrate for obtaining edible mushrooms, which are a raw material of interest in current food industry. The aim of the paper was the cultivation of Pleurotus ostreatus var. florida species, on diverse common plant wastes. The species had good fructification, resulting numerous pins on the surface of the substrate, the cap diameter reaching a maximum of 4 to 5 cm. The color of the basidium was brighter, because the cultivation temperatures were above 20°C most of the time. The fructification time decreased with the increase of inoculation rate. Although major differences haven’t been determined for morphological characteristics of the fructification body, the supplementation of the substrate formula with other components determined approximately 10% increase in productivity. The study proved that applying supplements to the substrate formula lead to the optimization of valorisation of plant wastes taken into consideration. Also, the use of supplements did not stimulate infection rate of the substrate.
