A basidiospore is a reproductive spore produced by basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis , and they are produced by specialized fungal cells called basidia .
When a basidiospore matures, sugars present in the cell wall begin to serve as condensation loci for water vapour in the air. Two separate regions of condensation are critical. At the pointed tip of the spore (the hilum) closest to the supporting basidium, Buller's drop builds up as a large, almost spherical water droplet.
These fungi are said to be homothallic, versus the normal heterothallic species with mating types. Others are secondarily homothallic, in that two compatible nuclei following meiosis migrate into each basidiospore, which is then dispersed as a pre-existing dikaryon. Often such species form only two spores per basidium, but that too varies.
Bracket fungi are typically tough and sturdy and produce their spores, called basidiospores, within the pores that typically make up the undersurface. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees.
Basidiospores are oval or elliptical in shape, smooth, hyaline, and thin-walled. [2] SEM image showing an enlarged view of the basidiospores on peridiole of bird's nest fungi SEM image of the funicular cord on the peridiole of bird's nest fungi Bird's nest fungi from the Missouri Ozarks

For the last seven years, Kammerer has been working with koji mold, or Aspergillus oryzae, which is widely used in Japanese cuisine to ferment soybeans and make things like soy sauce and miso. In ...
Heteroecious rust fungi require two unrelated hosts to complete their life cycle, with the primary host being infected by aeciospores and the alternate host being infected by basidiospores. This can be contrasted with an autoecious fungus, such as Puccinia porri , which can complete all parts of its life cycle on a single host species. [ 9 ]
