Honey mushroom in oregon: most fungi don"t produce mushrooms, largest organism on earth. Hyphae is the threadlike filaments of a fungus: these filaments are the building structure of the mycelium, they consist of a tubular cell wall containing chitin surrounding a plasma membrane and cytoplasm. Chitin is a structural polysaccharide of modified sugars of fungal cell walls. Septa are structures that partially separate the cytoplasm inside the hyphae. There have been over 100,000 fungal species identified and more are added each year. We will consider five of the major phyla of the kingdom fungi: chytrids - phylum chytridiomycota, zygomycetes - phylum zygomycota, mycorrhizal fungi phylum glomeromycota, club fungi- phylum basidiomycota, sac fungi- phylum ascomycota. Two of the main classification criteria for these groups are the presence (or absence) of septa and the differences in the sexual life cycle. The chytrids see chytrid filaments in fig. The zygomycetes: named for the zygosporangium, which has a thick cell wall (fig.
