Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores. [4] However, some Basidiomycota are obligate asexual ...
Diagram showing a basidiomycete mushroom, gill structure, and spore-bearing basidia on the gill margins. A basidium (pl.: basidia) is a microscopic spore-producing structure found on the hymenophore of reproductive bodies of basidiomycete fungi.
Most species can reproduce both sexually and asexually, alternating between haploid and diploid forms. This contrasts with most multicellular eukaryotes, such as mammals, where the adults are usually diploid and produce haploid gametes which combine to form the next generation. In fungi, both haploid and diploid forms can reproduce – haploid ...
The life cycle varies considerably. Some have a simple asexual life cycle, [16] while others have a complex life cycle involving multiple hosts and both asexual and sexual reproduction. Different types of spores may be produced at different stages, probably with different functions including autoinfection (transmission within a single host).
The fungi imperfecti or imperfect fungi are fungi which do not fit into the commonly established taxonomic classifications of fungi that are based on biological species concepts or morphological characteristics of sexual structures because their sexual form of reproduction has never been observed. They are known as imperfect fungi because only ...
Bioluminescent Mycena roseoflava Panellus stipticus, one of about 125 known species of bioluminescent fungi. Found largely in temperate and tropical climates, currently there are more than 125 known species of bioluminescent fungi, [1] all of which are members of the order Agaricales (Basidiomycota) with one possible exceptional ascomycete belonging to the order Xylariales.

A. muscaria poisoning has occurred in young children and in people who ingested the mushrooms for a hallucinogenic experience, [21] [54] [55] or who confused it with an edible species. A. muscaria contains several biologically active agents, at least one of which, muscimol , is known to be psychoactive .
An organism that lives within a plant; in mycology, specifically fungi that live within plants but do not show external signs or damage to the plants. This is usually endomycorrhizial fungi in root systems and asymptomatic fungi in aerial plant parts [108] endospore 1. An endogenous spore, e.g. a sporgangiospore, often resembling an ascospore. 2.
