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 ...
These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the atmosphere. [1] When basidiospores encounter a favorable substrate, they may germinate, typically by forming hyphae.
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 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 ...
An active dose in adults is approximately 6 mg muscimol or 30 to 60 mg ibotenic acid; [56] [57] this is typically about the amount found in one cap of Amanita muscaria. [58] The amount and ratio of chemical compounds per mushroom varies widely from region to region and season to season, which can further confuse the issue.
This is a list of families in the phylum Basidiomycota of kingdom Fungi.The Basidiomycota are the second largest phyla of the fungi, containing 31515 species. [1] The phylum is divided into three subphyla, the Pucciniomycotina (rust fungi), the Ustilaginomycotina (smut fungi), the Agaricomycotina, and two classes of uncertain taxonomic status (incertae sedis), the Wallemiomycetes and the ...
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.
