To evaluate the importance of searching newnaturally occurring strains to raise yields in mushroom production,eight wild and four commercial strains of Agrocybecylindracea were cultivated on wheat straw. Thehighest biological eYciencies (BE) (54.572.4%) wereobtained with three wild and two commercial strains whencultured on non-supplemented wheat straw. Rolled oats orsoybean Xours supplementation were tested using threeselected strains, increasing BEs up to 1.2, 0.5 and 0.7-fold,respectively. This eVect of supplementation was stronger inthe Asiatic wild strain, yielding up to 41.1 and 30% morethan the two other strains with rolled oats and soybeanXour, respectively. The Asiatic wild strain cultivated withsoybean Xour supplementation achieved an average biologicaleYciency of 179%, to our knowledge, the highestreported for this species. These results show the importanceof searching for new naturally occurring strains in combinationwith supplemented wheat straw substrate for raisingyields in A. cylindracea cultivation
