Hymenium
Hymenium
Hymenium (pronunciation: /haɪˈmiːniəm/) is a term used in Mycological studies to refer to the spore-bearing surface of a Fungal fruiting body where the cells are specialized for the production of sexual spores.
Etymology
The term 'Hymenium' is derived from the Greek word 'hymen', meaning membrane. This is in reference to the thin layer of tissue that forms the spore-bearing surface in many fungi.
Description
The Hymenium is a layer of highly specialized cells, known as basidia or asci, which are responsible for the production of sexual spores. This layer is typically found on the underside of the cap in basidiomycetes (such as mushrooms) and within the fruiting bodies of ascomycetes (such as yeasts and molds).
The structure and arrangement of the Hymenium can vary greatly among different groups of fungi. In some species, the Hymenium is smooth and continuous, while in others it is broken up into numerous individual projections, known as gills, pores, or teeth.
