basidia

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

在多数担子中，担子是由一个专可育层，即在子实体表面子实层形成。

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

真根据其“果实”（子实体译者注）结构特征分为三：接合、子囊和担子。
