Two experiments were conducted to determine the effects of supplementing wood chips and cottonseed hulls with brewer’s grain and SpawnMate IISE® (SMIISE) on yield and size of two strains of P. eryngii. On oak wood chips, biological efficiency (BE) ranged from 30.7% (5% brewer’s grain supplementation; strain WC827) to 54.1% (15% brewer’s grain supplementation; strain WC515). For strain 515, increasing brewer’s grain supplementation of oak chips from 5% to 15% increased yields by 41%, whereas for strain 827 the increase was only 19%. On cottonseed hulls, yields and BEs were highest for 45% brewer’s grain supplementation. Yield increases were not linear, however. As supplementation levels for brewer’s grain increased from 15 to 30%, yields increased 39%, whereas yields only increased an additional 15% when brewer’s grain in the cottonseed hulls substrate was increased from 30 to 45%. A similar trend was observed for SMIISE supplementation; i.e., as SMIISE was increased from 3 to 6% of the dry substrate weight, yield increased 90%, whereas an increase from 6 to 9% supplementation resulted in an additional 84% increase. Thus, the magnitude of the yield response was much greater for SMIISE® than for brewer’s grain supplementation.
