Introduction The economic viability of rare edible fungi remains critically underexplored, with significant data gaps hindering informed investment and policy decisions. This study addresses this gap by providing the first detailed economic analysis of intensive Dictyophora rubrovolvata ( D. rubrovolvata ) cultivation in China. Methods Environmental Life Cycle Costing (E-LCC) was applied alongside Monte Carlo simulation to evaluate production costs and financial risk. High-resolution inventory data were obtained from a commercial cultivation facility to ensure analytical precision and full cost transparency. Results The total unit production cost was determined to be 204.82 CNY/kg, incorporating both internal expenditures and monetised environmental externalities (3.40 CNY/kg). The cost structure exhibits a distinct “hybrid” economic profile, dominated by capital depreciation from greenhouse facilities (41.9% of total cost) and high-skilled labour requirements (40.0%), confirmed as primary cost drivers through Pareto analysis. Sensitivity analysis further identified labour efficiency and yield stability as the critical determinants of financial risk. Discussion Given the estimated break-even cost floor, D. rubrovolvata is unlikely to compete as a scalable mass-market commodity crop. Its long-term economic sustainability is strictly contingent upon premium pricing strategies, positioning it as a high-input luxury product rather than a cost-minimisation venture. These findings offer essential benchmarks and full inventory transparency for investors and policymakers.
