The basidiaof Uredineae (Rusts) and of some other primitive Basidiomycetes are septate, but otherwise agree with the type described above.
The basidia are arranged in a continuous layer (hymenium), and are usually massed together upon a specialized fruit-body, of which an ordinary mushroom is a good example.
Receptacle cup-shaped or globose; spores produced on sporophores or short basidia enclosed in globose or disciform bodies (sporangia) contained within a distinct peridium.
Cystidia, sterile cells of the hymenium, generally larger than the basidia cells, with which they are found.
In the young stage the basidia in the Hypogaei are easily distinguished by the aid of the microscope.
The basidia of the Gasteromycetes, though resembling those of the Hymenomycetes, are more variable in form and the number of the spores not so constant.
The hymenium consists of elongated cells or basidia (singular, basidium) more or less club-shaped.
The hymenium is universal; the basidia round and two-lobed, each lobe bearing a single one-spored sterigma.
Among these basidia and sterile cells will frequently be seen an overgrown bladder-like sterile basidium which projects beyond the rest of the hymenium, and whose use is not as yet fully known.
Figure 2 will show how these basidia appear on the hymenial layer when strongly magnified.
In Figure 2 a number of sterile cells will be seen which resemble the basidia except that the latter bear four sterigmata upon which the spores rest.
Gills, plates radiating from the stem on which the basidia are borne.
The youngbasidia as seen in Figure 2 are filled with a granular protoplasm.
Upon each of these basidia are in some species two, usually four, slender projections upon which the spores are produced.
The basidia are nearly round with four rather stout, elongated sterigmata, spores very nearly round.
Soon small projections, called sterigma (plural, sterigmata), make their appearance on the ends of the basidia and the protoplasm passes into them.
The spores are borne on basidia as explained in Figure 2, page 6.
Basidia exhausted entirely of their contents, and which have become quite hyaline, may often be observed.
As the spores approach maturity, the connection between their contents and the contents of the basidia diminishes and ultimately ceases.
Léveillé[O] was of opinion that the basidia of the Tremellini were monosporous, whilst M.
The hymenium is sinuous and convolute, bearing basidia with sterigmata and spores in the cavities.
All parts of these reddish individuals seemed more or less infected with this disintegration, the basidia divided by transverse diaphragms into several cylindrical or oblong pieces, which finally become free.
Hymenium= perfectly even or radiately wrinkled, glabrous or minutely bristled with projecting cystidia; basidia normally 4-spored.
SPIC´ULE (spicula, a little sharp point), in Hymenomycetes one of the small projections on the basidia which bear the spores.
Petersii has a transversely divided basidium as in Auriculariaceae, but the basidia are surrounded with a peridium-like sheath.
Exobasidium) thebasidia are borne directly on the ordinary mycelium, but in the majority of cases the basidia are found developed in layers (hymenium) on special sporophores of characteristic form in the various groups.
Most of Basidiomycetes are characterized by the large sporophore on which the basidia with its basidiospores are borne.
The Tremellinaceae are characterized by the possession of basidia which are divided by two vertical walls at right angles to one another.
In this by far the larger division of the Basidiomycetes the basidia are undivided and the four basidiospores are borne on short sterigmata nearly always at the apex of the basidium.
If the gills have been bruised, the spores are easily rubbed off, and their connexion with the basidia destroyed.
In the family Tremellini the receptacle forms a gelatinous mass, and the basidia are situated upon its surface, terminating the filaments of which it is composed.
The layer just beneath the basidia is usually more or less modified, being often composed of small cells different from the rest of the trama.
Plants gelatinous or sub-gelatinous, basidia forked, or divided longitudinally or transversely.
The basidia are abruptly club-shaped, rather distant and separated regularly by rounded cells, four spored.
The basidia are peculiar to the order, are deeply seated in the substance of the plant, rounded or globose, and divided into four cells in a cruciate manner.
They resemble each other very much, except that the basidia bear four sterigmata and a spore on each.
These sacs, or asci, are grouped together, lying side by side, forming the fruiting surface or hymenium, much as the basidia form the fruiting surface in the mushrooms.
The basidia are like those of the genus, globose, sunk in the substance of the plant, and terminate with four long, slender, sterigmata which rise to the surface and bear the spores.
The spores are borne on club-shaped basidia within the chambers of the fruit-bearing portion (gleba), and at maturity of the spores the stem or receptacle begins to elongate.
The basidia are formed on the end of threadlike branched bodies which grow at the apex, and are called hyphæ.
The basidia are called mother-cells because they produce the spores.
On top of the basidia are minute stalk-like branches, called sterigmata (singular sterigma), and each branch carries a naked spore.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "basidia" in a variety of sentences. We hope that you will now be able to make sentences using this word.
