2. Fungus-related terms Saprobe
3. Fungi Cellular Characteristics
Have cell walls reinforced with chitin
Diploid only during sexual reproduction
4. Basidiomycetes Examples—mushrooms, rusts, smuts, puffballs
Basidia—club shaped reproductive structure found on the gills.
Formation of haploid spores
7. Ascomycetes Sac Fungi
Truffels, Morels, Penicillium, Yeasts, Candida albicans, Saccharomyces cervisiae, Sordaria
10. Zygomycetes Terrestrial Fungi

13. Imperfect Fungi Taxonomic holding station
Scientists have not discovered a sexually reproductive stage in these organisms
Candida and Penicillium were both once categorized in this group.
14. Fungal Symbiosis Mycorrhizae—Mutualistic association between tree roots and fungi. Help to increase water absorption.
Lichens—Mutualistic association between fungi and cyanobacteria. Play a role in primary succession.
