Major Groups of Fungi

Table 23.1 Major Groups of Fungi Groups with aseptate hyphae composed of haploid cells: Chytrids 1,000 species. Make spores asexually and sexually. Spores and gametes flagellated. Live in seawater, fresh water, moist soil, and in or on other organisms. Zygote Fungi (Zygomycetes) 1,100 species. Make spores asexually and sexually Live in soil, and inside or on other organisms. Some species are human pathogens. Glomeromycetes 150 species. Not known to reproduce sexually. All live inside plant roots without harming the plant. Groups with septate hyphae; each hypha may be haploid or dikaryotic: Sac Fungi (Ascomycetes) More than 32,000 species. Make spores asexually and sexually. Live in soil, and inside or on other organisms. Some are human pathogens. Some partner with photo- synthetic cells and form lichens. Club Fungi (Basidiomycetes) More than 26,000 species. Make spores asexually and sexually. Include species with the largest and most complex spore»bearing structures. Live in soil, and inside or on other organisms.
