A basidium usually bears four sexual spores called basidiospores. Occasionally the number may be two or even eight. Each reproductive spore is produced at the tip of a narrow prong or horn called a sterigma (pl. sterigmata), and is forcefully expelled at full growth. The word basidium literally means "little pedestal". This is the way the ...
Agaricus bisporus basidiospores. A basidiospore is a reproductive spore produced by basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. ...
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.
In the human pathogenic genus Cryptococcus, four nuclei following meiosis remain in the basidium, but continually divide mitotically, each nucleus migrating into synchronously forming nonballistic basidiospores that are then pushed upwards by another set forming below them, resulting in four parallel chains of dry "basidiospores". [citation needed]
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).
It is set in Pacific Grove, California, and on Basidium, a tiny habitable moon of Earth, invisible from the planet in its orbit 50,000 miles away. The "Mushroom Planet", visited by the protagonists David Topman and Chuck Masterson, is covered in various types of mushrooms and is populated by little green people who are in a state of distress.
Mature basidia with two, three, and four spores; 4. Basidium collapsing with spores still attached; 5. Spores immediately after separation from basidia, showing conspicuous apiculus; 6. Older spores; apiculus nearly or quite gone." [3] Cyathus olla bears a resemblance to a miniature bird's nest containing eggs, hence the common name bird's nest ...
Heterobasidion annosum is a basidiomycete fungus in the family Bondarzewiaceae.It is considered to be the most economically important forest pathogen in the Northern Hemisphere.
