Agaricus bisporus basidiospores. 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.
Armillaria mellea infects both through basidiospore [20] and penetration of host species by rhizomorphs [19] which can grow up to 1 meter (39 in) long per year [27] to find new, living tissue to infect. [20] However, infection of living host tissue through basidiospores is quite rare. [22]
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".

The tubes offer shelter for developing spores and help to increase the area of the spore-producing surface. Pore size and shape vary a lot between species, but little within a species – some Hexagonia spp. have 5 mm wide pores whereas pores of Antrodiella spp. are invisible to naked eye with 15 pores per mm. Generally the larger the pores ...
They sometimes have sterile cells scattered around and sometimes have a sterile cortex. The teliospores are globose or irregularly faceted, hyaline or yellowish, smooth, thin walled, germinating to form a short hypha-like promycelium from which a cluster of basidiospores are produced towards an apex.

Amid growing anxieties surrounding reported drone sightings, the FBI has issued a warning against a new trend of pointing lasers at aircrafts.
Puccinia horiana is a microcyclic, autoecious rust, meaning that the fungus has two known spore stages: teliospores and basidiospores, as well as no known alternate host. [6] Similar to other microcyclic rusts, two-celled teliospores produce unicellular basidiospores which are then dispersed via air currents.
