Trama (mycology) Trama (mycology) In mycology, trama 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. In essence, the trama is the tissue we call the "flesh" of mushrooms and similar fungi. Literally, "trama" is the Latin word for the "weft" or "woof" yarns in the weaving of cloth. This probably is related to the basidiocarp trama being "filler" tissue and that analogously the woof yarn in weaving is sometimes called "fill". Furthermore, the
Division (biology) comprising 80% of vascular plant species. In zoology, the term "division" is applied to an optional rank subordinate to the infraclass and superordinate to the cohort. A widely used classification (e.g. Carroll 1988) recognises teleost fishes as a Division Teleostei within Class Actinopterygii (the ray-finned fishes). Less commonly (as in Milner 1988), living tetrapods are ranked as Divisions Amphibia and Amniota within the clade of vertebrates with fleshy limbs (Sarcopterygii). Division (biology) Division is a taxonomic rank in biological classification that is used differently in zoology and in botany. In botany and mycology, "division" refers to a rank equivalent to
