Question

classification of fungi by Alexopoulous , Mims and Blackwell ?​

Answer 1

Answer:

The outline of the classification is given:

Kingdom. Myceteae (Fungi):

Achlorophyllous, saprobic or parasitic organisms with uni­cellular or more typically, filamentous soma (thallus), usually surrounded by cell walls that characteristically consists of chitin and other complex carbohydrates, nutrition absorptive, except in the slime molds (Division Gymno- mycota) where it is phagotrophic, propagation typically by means of spores produced by various types of sporophores; asexual and sexual reproduction usually present.

The kingdom is subdivided into three major divisions:

A. Division. Gymnomycota:

Phagotrophic organisms with somatic structures devoid of cell walls:

a. Subdivision. Acrasiogynomycotina:

1. Class. Acrasiomycetes

b. Subdivision. Plasmodiogymnomycotina:

1. Class. Protosteliomycetes

2. Class. Myxomycetes

B. Division. Mastigomycota:

Fungi with centrioles; flagellate cells typically produced dur­ing the life cycle; nutrition typically absorp­tive; varying from unicellular that becomes converted into a sporangium, to an exten­sive, filamentous, coenocytic mycelium, asexual reproduction typically by zoospores; sexual reproduction by various means:

a. Subdivision. Haplomastigomycotina

1. Class. Chytridiomycetes

2. Class. Hyphochytridiomycetes

3. Class. Plasmodiophoromycetes

b. Subdivision. Diplomastigomycotina

1. Class. Oomycetes

C. Division. Amastigomycota:

Fungi without centriole, no motile cells, nutrition absorp­tive, single-celled to mycelial with a limited or extensive, septate or aseptate mycelium, asexual reproduction by budding, fragmen­tation, sporangiospores or conidia; sexual reproduction, where known, by various means; haplobiontic-haploid life cycle with zygotic meiosis.

a. Subdivision. Zygomycotina

1. Class. Zygomycetes

2. Class. Trichomycetes

b. Subdivision. Ascomycotina

1. Class. Ascomycetes

c. Subdivision. Basidiomycotina

1. Class. Basidiomycetes

d. Subdivision. Deuteromycotina

1. Form class. Deuteromycetes.
