1. Phylum :Basidiomycota.
General characters:
The sexual reproduction produce basidiospores.
No flagellate cells are present.
Dikaryotic phase long dikaryotic mycelium. (may have clamp connection).
Presence of dolipore septum
(septated mycelium).

2. 5. Basidiomycota: parasites rust fungi smut fungi Saprophytes. 6
5.Basidiomycota: parasites rust fungi smut fungi Saprophytes. 6. Cell wall contain high amount of chitin. 7. Forming marcroscopic fruiting bodies. 8. Asexual reproduction by conidia,chlamdospores

3. The dolipare septum:
Found in all basidiomycota except the rust fungi
It consist of central preforated swelling over which there is a pore cap
The dolipare septum regulates the passage of nuclei and organelles from one cell to another by opining and closing

4. The clamp connection:
Found in all dikaryotic mycelia of basidiomycota except for most uredinomycetes

5. phragmobasidium holiobasidium teliobasidium
The basidium:
The basidium is the organ in which karyogamy and meiosis take place, result in formation of 4basidiospores externally on the basidium.
Types of basidia
phragmobasidium holiobasidium
teliobasidium

6. Diplodization or dikaryotization:
Is the process in which a primary mycelium converted into secondary myclium.

7. Class:Basidiomycetes
Basidiomycota
Class:Basidiomycetes
*produce one type of spores during their life cycle.
*most species are saprophytes.
Class:Uridinomysetes
*produce more than one type of spores.
*most are parasites causing rust disease.
Class:Ustomycetes
*produse more than one type of spores
*most are parasites causing smut disease

8. *Life cycle of the basidiomycetes:

9. Puccinia

10. Class:Urediniomycetes
General characters:
The mycelium has no clamp connection or dolipore septum.
Obligate parasites causing rust disease.
Heteroeious( require two different species of plant host to complete life cycle).
Heterothalic(have two diffrenet mating types -.+).
Sexual reproduction takes place by spermatization between spermatia and receptive hypae.
Life cycle is very complex.

Family:Melampsoracae
teleutospores are sessile and united together
Melampsora Lini

12. Puccinia :
Causing rust disease.
Plant Health Management
