Definition

Noun A lichen in which the fungal partner (mycobiont) belongs to the phylum Ascomycota. Ascolichens constitute the majority of lichen species.

Usage

Advanced Usage

• The term is often used in contrast to basidiolichen, which is a lichen where the fungal partner is a basidiomycete.
• In taxonomic descriptions: " is a common foliose ascolichen."

Variants and Related Words

• Ascolichenized (adj.): Referring to an ascomycete fungus that has formed a lichen symbiosis.
  • The ascolichenized state of the fungus was confirmed.
• Basidiolichen (n.): A lichen with a basidiomycete fungus as the mycobiont.
