块菌是一种极为名贵的食用菌,味道独特,营养丰富,价钱奇贵。特别是在西欧和北美,食物品尝家(美食者)无不为之垂涎和倾倒。最近,还有所谓“块菌品尝家欧洲游”的旅游事业在西方兴起,旅游者花二千多美元既可品尝风味独特的鹅肝酱馅饼,又可享受亲自挖出一只块菌的快乐。块菌的价格由于货源不断减少而上涨,巴黎市场一磅达200美元(1964年仅10美元),纽约市场高达600美元以上。因而,块菌的研究不仅引起了科学家的兴趣,而且一些国家的政府和财团也积极支持赞助这一研究。块菌西方人称之为“Truffle”。在法文中Truffle 指的是Perigord Truffle,即黑孢块菌
Truffle is an extremely valuable edible fungus, unique taste, nutrient-rich, the price is extremely expensive.
