Thelomma ocellatum

Thelomma ocellatum is a crustose lichen inactive species that belonged to the family Caliciaceae. It was first described by Körber and later reassigned by Tibell in 1976. Since 2020, the species has been declared inactive and was swapped with Pseudothelomma ocellatum.

Although frequently sterile, the species can sometimes be found with apothecia that are reminiscent of the related lichen Cyphelium inquinans. Thelomma ocellatum is always sorediate-isidiate.
