Septate.
What kind of spores do Ascomycota produce?
Sexual spores called Ascospores and asexual spores called Conidia.
What is the fruiting structure of Ascospores called?
Asci
What is an example of an Ascomycota that has no ascocarp?
Yeast
Name the 4 classes of Ascomycota.
- Cleistothecium
- Perithecium
- Psedothecium
- Apothecium
What kind of an ascocarp does Cleisothecium have?
Closed ascocarp
What kind of an ascocarp does Perithecium have?
Ascocarp with ostisole. Ostisole helps push out spores.

The blooms.

- Mushroom
- Shelf-fungi
- Rust
- Smuts
Name one fungus under basidiomycetes.
Rhizoctonia
What kind of spores are produced by basidiomycetes?
Basidiospores.
What kind of spores do Rhizoctonia produce?
Rarely produce basidiospores.
What are the results of a plant infected with Rhizoctonia?
Damping off and rots.
What is the difference between brown rots and white rots?
