Breads were prepared from wheat flour supplemented with oyster mushroom (Pleurotus ostreatus) powder, and effects of the supplementation of oyster mushroom powder on dough rheology and bread quality were examined. The initial pasting temperature in viscoamylograph increased, but peak and final viscosities decreased with the increased amount of oyster mushroom powder. The gradual increase of water absorption, dough development time and mixing tolerance index, and decrease of dough stability with the increased amount of oyster mushroom powder were obtained by farinographs. The supplementation of oyster mushroom powder had an effect on the bread making, resulting in an increase of loaf weight and a decrease of loaf volume. The rough and coarse crumb texture with dark color was observed with the increased amount of oyster mushroom powder. The firmness of bread crumb containing oyster mushroom powder was increased during storage periods. Sensory evaluation revealed that the addition of $1\%$ oyster mushroom powder could be supplemented to make an acceptable quality of bread.
