Wild edible mushroom demand has increased substantially in OECD countries in the last few years. Nevertheless, few studies have been published in recent years on these markets. The main objective of this paper is to characterise the saffron milk cap (Lactarius deliciosus Fr.) demand in Spain. Data sources in this study come from main Central Markets in Spain. Using econometric methods, we have found that the consequence of an increase in the price of the saffron milk cap has a negative effect on demand. However, changes in the percentage of persons born in Catalonia every year exercise a positive effect, and price increases in the Madrid market could also induce an increase in the Lactarius deliciosus demand in the Barcelona Central Market. The consequences of chanterelle imports on the Catalan demand for the saffron milk cap appear to be negative. Finally, results indicate that the saffron milk cap and oyster mushroom behave as complementary goods and, therefore, consumption of one of these mushrooms reinforces the other's consumption.
