Pseudothelomma is a genus of crustose pin lichens in the family Caliciaceae. It contains two species. The genus was established in 2016 when DNA analysis revealed that two species previously classified in the genus Thelomma were actually distinct and formed their own separate evolutionary group. These lichens are distinguished by their preference for growing on dry, bark-free conifer wood and their black, flat spore-bearing structures that may have a greenish-yellow powdery coating.
