Ascomycetes

Ascomycetes

This classification has since been invalidated. The current classification is Ascomycota, Taxonomic Serial No.: 610624

"Terrestrial and aquatic fungi with the hyphae septate but the septa perforated; complete septa cut off the reproductive bodies, such as spores or gametangia. Chitin is predominant in the cell walls. Sexual reproduction involves the formation of a characteristic cell, the ascus, in which meiosis takes place and within which spores are formed. The hyphae in many ascomycetes are packed together into complex "fruiting bodies" known as ascocarps. Yeasts are unicellular ascomycetes that reproduce asexually by budding. There are about 30,000 species."

Protostelidomycetes

"In this recently discovered group, the amoebas may remain separate or mass, but each one eventually differentiates into a simple stalked sporangium with one or two spores at its apex. Five genera and more than a dozen species."

"Cellular slime molds. Slime molds in which there are separate amoebas which eventually swarm together to form a mass but retain their identity within this mass, which eventually differentiates into a compound sporangium. Seven genera and about 26 species."
