Fungal Cladogram PilobolusPeziza Phallus Agaricus Mucor Rhizopus Saccharomyces Sordaria Polyporus Neurospora To Animalia, etc. Phylum: AscomycotaBasidiomycotaZygomycota One other taxon: Deuteromycota is artificial as sexual stages are unknown for these species. They are likely Ascomycota.
Basidiomycota: Amanita virosa (the destroying angel mushroom) lamellae = gills annulus = ring stipe = stalk volva = cup pileus amatoxin: digestive upset, fever, 2 days, improve 3 days, coma, death
Life Cycle of Agaricus septate hypha 4 meiotic products extruded from basidium SYNGAMY zygote SporophyteGametophyte sporangium sporocyte spores gametangia gametes germination mitosis differentiation mitosis germination mitosis 1N 2N differentiation MEIOSIS Whether 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. karyogamy 4 basidiospores atop basidium plasmogamy meiosis basidium 2N cup = volva stalk = stipe cap = pileus This 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 mycelium gills = lamellae ring = annulus
Basidiomycota: Amanita muscaria (fly agaric) mushroom ibotenic acid, muscimol hallucinogenic near lethal dose Passage through urine stream Smurf Homes?
Basidiomycota: 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
A 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?
Basidiomycota: Boletus a large polypore (sponge) mushroom The pores are lined with basidia producing basidiospores
Basidiomycota: Psilocybe cubensis s/Bradenton/Neil%207.jpg Growing in natural setting Dry for sale These magic mushrooms contain psilocybin, a mescaline-class hallucinogen
