1. Zygomycetes Sexual gametangia are similar Hyphae are coenocytic.
Classification of Eumycota True fungi are grouped into five classes based on their method of reproduction, these classes are :
Zygomycetes
Sexual gametangia are similar
Hyphae are coenocytic.
Ascomystes
Spores are endogenous, i.e. produced inside special sacs called asci.
Hyphae are septated.
Oomycetes
Sexual gametangia are dissimilar, being distinguished into female gametangia or oogonia and male gametangia or antheridia.
Hyphae are coenocytic.
Deuteromycetes
(Imperfect fungi)
Its perfect stage or its mode of sexual reproduction is not yet known until now.
Hyphae are septated .
Basidiomycetes
Spores are exogenous, i.e. produced externally on basidia.
Hyphae are septated.

2. Non septated Hyphae
of Aspergillus niger
Septated Hyphae
of Penicillium

3. Endogenous Spores (Ascus)
Rhizopus
Similar gametangia
Endogenous Spores (Ascus)

5. Oomycetes (oogonia and antheridia)

6. Exogenous Spores (conidia)

7. Class: Zygomycetes
The hyphae are coenocytic ( non-septate) without cross walls except where the reproductive organs are cut.
The hyphae are filled or lined with continuous multinucleated protoplasm.
This class includes both parasitic and saprophytic species.

8. Rhizopus ( Black bread mould ) عفن الخُبز الأسود
*It is a saprophytic fungus, which can grow on moist bread, stored fruits, vegetables, and synthetic nutritive media. *It is called bread mould since it is mostly seen growing on damp bread.
Vegetative structure.
The mycelium consists of branched non-septate hyphae, which grow creeping upon the substratum and called stolons
Each stolon sends branched rhizoids to the substratum for absorption of the necessary food material.
Opposite to the rhizoids, clusters of erect aerial sporangiophores arise, each terminating with a single sporangium.
The hypha is full of multinucleated protoplasm.
