What is hymenium layer?
What is hymenium layer?
hymenium, a spore-bearing layer of tissue in fungi (kingdom Fungi) found in the phyla Ascomycota and Basidiomycota. It is formed by end cells of hyphae—the filaments of the vegetative body (thallus)—which terminate elongation and differentiate into reproductive cells.
Where is the hymenium on a mushroom?
In agarics, the hymenium is on the vertical faces of the gills. In boletes and polypores, it is in a spongy mass of downward-pointing tubes. In puffballs, it is internal. In stinkhorns, it develops internally and then is exposed in the form of a foul-smelling gel.
What is hymenium in Peziza?
(b) Hymenium region consists of many fertile asci and sterile paraphyses. (c) Sub-hymenium is made up of pseudo- parenchymatous hyphae which later on form the peridium of the cup. (d) In each ascus are present eight uninucleate ascospores which form the new mycelium on germination.
What are the three parts of a basidiocarp?
secotioid fungus – like a gasteromycete, but with a stalk. Thought to be an evolutionarily intermediate stage between a gasteromycete and an agaric. agaric or gill fungi – fruiting body with caps, gills, and (usually) a stalk. bolete – fleshy fruiting body with a cap, a stalk, and tubes on the underside.
Who is the father of mycology?
Heinrich Anton de Bary
Heinrich Anton de Bary, (born Jan. 26, 1831, Frankfurt am Main [Germany]—died Jan. 19, 1888, Strassburg, Ger. [now Strasbourg, Fr.]), German botanist whose researches into the roles of fungi and other agents in causing plant diseases earned him distinction as a founder of modern mycology and plant pathology.
What is a fruiting structure?
A fruiting body is a multicellular structure on which spore-producing structures, such as basidia or asci, are born. Fruiting body may also refer to: Fruiting body (bacteria), the aggregation of myxobacterial cells when nutrients are scarce. Fruiting body (slime mold), the sorophore and sorus of a slime mold.
What is apothecium in Peziza?
A fruiting body of species of Peziza is mostly cup or disc-shaped called an apothecium. The apothecia are mostly sessile but sometimes stalked, minute to very large (0.5-10.0 cm or more in diameter), brightly colored (but lacking carotenoids) to dark brown; smooth, velvety, hairy or bristly.
What are the structures of the Peziza?
Peziza, which contains about 50 widespread species, produces in summer a cup-shaped fruiting body or mushroomlike structure on rotting wood or manure. Fire fungus is the common name for two genera (Pyronema and Anthracobia) of the order that grow on burned wood or steamed soil.
What is the function of a basidiocarp?
Basidiocarp is a fruiting body in basidiomycetes. It bears basidium where basidiospores are formed during sexual reproduction.
What is basidiocarp membranous structure?
Basidiocarp. The mature basidiocarp is umbrella shaped and is divided into 3 parts namely stipe, pileus and gill. The stipe is thick, fleshy and cylindrical in structure. The upper part of the stipe possess a membranous structure called annulus.
Who discovered fungi first?
The medical relevance of fungi was discovered in 1928, when Scottish bacteriologist Alexander Fleming noticed the green mold Penicillium notatum growing in a culture dish of Staphylococcus bacteria.
