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".

Sexual spores called basidiospores are created in the fertile layer on the lower surface of the basidiocarps, whilst conidiospores occur in the asexual stage and are produced on microscopic "conidiophores" which erupt through the surface of the host tree. Conidiospores and basidiospores are both produced by this fungus, the latter being more ...
In human infection, C. neoformans is spread by inhalation of aerosolized basidiospores or dehydrated fungal cells, and can disseminate to the central nervous system, where it can cause meningoencephalitis. [22] In the lungs, C. neoformans cells are phagocytosed by alveolar macrophages. [23]
Sporobolomyces is a genus of fungi in the subdivision Pucciniomycotina. [3] Species produce both yeast states and hyphal states. The latter form teliospores from which auricularioid (tubular and laterally septate) basidia emerge, bearing basidiospores.
Their spores, called basidiospores, are produced on the gills and fall in a fine rain of powder from under the caps as a result. At the microscopic level, the basidiospores are shot off basidia and then fall between the gills in the dead air space. As a result, for most mushrooms, if the cap is cut off and placed gill-side-down overnight, a ...
However, infection of living host tissue through basidiospores is quite rare. [22] Two basidiospores must germinate and fuse to be viable and produce mycelium. [22] In the late summer and autumn, Armillaria mellea produces mushrooms with notched gills, a ring near the cap base, and a white to golden color. [25]
When ants bite humans, it grabs the skin and also sprays a compound called formic acid, Frye explains. Ant bites tend to be small, swollen bumps that appear in clusters, Kassouf says.
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.
