basidia

Hymenium (pl. hymenia) A layer of the fruiting body of certain ascomycete and basidiomycete fungi in which the asci or basidia are borne.

真菌根据其“果实”（子实体译者注）结构特征分为三大门类：接合菌类、子囊菌类和担子菌类。

In most basidiomycotes the basidia are borne on a special fertile layer, the hymenium, on the surface of a fruiting body, the BASIDIOMA.

大多数的担子菌中，担子是由一个专门的可育层，即子实体表面的子实层形成的。
