Lecanorine lichen

The scrunched up apothecia discs of Lecanora muralis have rims that are made of tissue similar to the underlying body, so are said to be lecanorine.

A lichen has lecanorine fruiting body parts if they are shaped like a plate with a ring around them, and that ring is made of tissue similar to the main non-fruiting body part of the lichen.^[1] The name comes from the name of the lichen genus Lecanora, whose members have such apothecia.^[1] If a lichen has lecanorine apothecia, the lichen itself is sometimes described as being lecanorine.
