Basidiomycota (/ b ə ˌ s ɪ d i. oʊ m aɪ ˈ k oʊ t ə /) [2] is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. [3]
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores.In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia (basidiomycetes) or paraphyses (ascomycetes).
Basidiolichen mycobionts consist of 172 known species (0.9% of the total number of accepted lichen species) across 15 genera, 5 families, and 5 orders within the class Agaricomycetes in the fungal division Basidiomycota. [1]

In mycology, the term trama is used in two ways. In the broad sense, it is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body.It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium.
The Ascomycota is characterized by a high degree of specialization; for instance, certain species of Laboulbeniales attack only one particular leg of one particular insect species. Many Ascomycota engage in symbiotic relationships such as in lichens—symbiotic associations with green algae or cyanobacteria —in which the fungal symbiont ...
All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi.
Diagram showing a basidiomycete mushroom, gill structure, and spore-bearing basidia on the gill margins. A basidium (pl.: basidia) is a microscopic spore-producing structure found on the hymenophore of reproductive bodies of basidiomycete fungi. The presence of basidia is one of the main characteristic features of the group.
