Phycomycetes

Tubular Fungi

Phycomycetes (tubular fungi) are perhaps the most primitive of the true fungi. The mold you see growing on bread, rusts and mildews all belong to this group. Most species have tubes of protoplasm (hyphae) without dividing cell walls and many nuclei distributed throughout the cytoplasm. Some Phycomycetes live as parasites on other living things. [CH] {EB}
