Bio Lecture Notes for 10/20/09: (Know the sexual life cycles of fungi) Two main types of fungi: Yeasts are unicellular AND Molds are multicellular Ascomycota asexual reproduction Sexual reproduction Heterothallic / Homothallic Dikaryotic and monokaryotic hyphae grow together to form an ascocarp (a tightened pack of myceleal mass). The tips of the dikaryotic hyphae protrude from the center of the ascocarp; these protruding things are the asci. Yeast can undergo asexual or sexual reproduction. Asexual is the process of budding. Sexual reproduction produces only 4, rather than 8, ascospores. Basidiocarps /Basidiomycota (common mushrooms) mostly reproduce only sexually. Most of their mycelia are underground. They are heterophallic. In sexual reproduction, you’ll have a plus mycelium and a minus mycelium (they are called the primary mycelia) that need to come together for sexual reproduction to occur. The two hyphofilaments from the plus and minus strain will grow together (thereby providing the secondary dikaryotic mycelium). Plasmogamy will occur and they’ll fuse to form a
