Ascomycota
Definition
Ascomycota is a phylum of fungi characterized by the formation of spores in sac-like structures called asci. They include yeasts, molds, and more complex forms such as truffles and morels.
5 Must Know Facts For Your Next Test
- Ascomycota reproduce both sexually through asci and asexually through conidia.
- They are known for their role in decomposing organic material, making them essential to nutrient cycling.
- Many species within Ascomycota form symbiotic relationships with plants (mycorrhizae) or algae (lichens).
- Some Ascomycota species are pathogenic to plants and animals, including humans.
- Ascomycota includes economically important fungi used in baking, brewing, and antibiotics production like Penicillium.
