Study Notes
Systemic Classification of Fungi
- Phycomycetes: characterized by non-septate hyphae and production of endogenous asexual spores (sporangiospores) within sporangia, with oospore and zygospore as sexual spores.
- Ascomycetes: distinguished by formation of sexual spores (ascospores) in a sac called ascus, includes yeasts and filamentous fungi, and has septate hyphae.
- Basidiomycetes: reproduces through sexual reproduction, producing basidiospores at the tip of basidium, and has septate hyphae.
- Fungi imperfecti: a group of fungi where sexual phases have not been identified, including Sporothrix schenkii.
Structure and Reproduction of Fungi
- Fungi can be either unicellular or multicellular organisms.
- Yeasts: reproduce by a progenitor cell pinching off a portion of itself to produce a progeny cell, which may elongate to form sausage-like pseudohyphae, and produces round, pasty, or mucoid colonies on agar.
- Molds: multicellular organisms composed of threadlike tubular structures called hyphae, which elongate at their tips through apical extension.
- Hyphae: can be either coenocytic (hollow and multinucleate) or septate (divided by partitions or cross-walls).
