Chapter 2: What Fungi Do & How Starts with spore Cell wall expands through preformed weak spot ( germ pore ) = thin, balloon-like protuberance Germ tube = 1 st extension of growth Hyphae = elongations of the germ tube Mycelium = large collection of hyphae “Spawn” = masses of hyphae Mycotoxins = fungal by-products that are poisonous to animals, or antibiotics, which are metabolites that inhibit growth of microbes, may also permeate the substrate Food runs out need spores Conidia (fragments of the parent culture) or result from sexual reproduction (rapid evolution of new strains of a given species) Underside of gills = elongated balloons Smooth = immature or spacer cells Basidia Sclerotia Reproduce By… wind (inky cap) bioluminescence cup-like fruit-bodies inside a sac (8 spores, instead of 4) - Mother cell is able to contain spores until water pressure causes weaker part to give way
