Final answer:
The fungal component of lichens belongs to the divisions of Ascomycota and Basidiomycota.
Step-by-step explanation:
The fungal component of lichens belongs to the divisions of Ascomycota and Basidiomycota.
Lichens are mutualistic associations between fungi and either green algae or cyanobacteria (or both). The fungal component of lichens is known as the "mycobiont." The mycobiont is typically a member of the fungal division Ascomycota, and it forms a symbiotic relationship with the photosynthetic partner (the algal or cyanobacterial component), referred to as the "photobiont."
