64 basidiospores atop basidium Life Cycle of AgaricusThis dikaryotic mycelium is composed of septate hyphae. It proliferates in the substrate (soil, rotting wood, etc.) and can live this way for weeks, years, decades, even centuries! Under the correct conditions, the dikaryotic mycelium forms basidiocarps. These will have hyphal tips forming a layer (a hymenium) on gills (or other surfaces). The apical cells are called basidia.dikaryotic myceliumplasmogamycap = pileusSYNGAMYzygoteSporophyteGametophytesporangiumsporocytesporesgametangiagametesgerminationmitosisdifferentiation1N2NMEIOSISstalk = stipegills = lamellaering = annulusseptatehyphacup = volvabasidium 2Nkaryogamymeiosis4 meiotic products extruded from basidium4 basidiospores atop basidiumWhether this is a zygotic or a sporic life cycle depends upon your interpretation of whether or not the dikaryotic mycelium and basidiocarp is a sporophyte.
7Basidiomycota: Amanita muscaria (fly agaric) mushroom ibotenic acid, muscimol hallucinogenic near lethal dosePassage through urine streamSmurfHomes?
8Basidiomycota: Coprinus comatus (inky cap) mushroom Fall mushroom, edible as long as you do not drink alcohol at the same meal. Alcohol converts an innocuous compound into a toxin.Distinctive cylindrical pileus with shaggy coverage. Also called the shaggy-mane mushroom
9A Fairy Ring of Mushrooms: a dikaryotic mycelium producing an ever-larger circle of basidiocarps at it edge. Can you tell how the lawn responds? Why does it respond this way?
10Basidiomycota: Boletus a large polypore (sponge) mushroom The pores are lined with basidia producing basidiospores
13Basidiomycota: Psilocybe cubensis These “magic mushrooms” contain psilocybin, a mescaline-class hallucinogenGrowing in natural settingDry “for sale”
