Dictyomeridium is a genus of corticolous (bark-dwelling), crustose lichens in the family Trypetheliaceae.[1] It has nine species.
The genus was circumscribed in 2016 by lichenologists André Aptroot, Matthew Nelson, and Robert Lücking, with Dictyomeridium proponens assigned as the type species. The seven species they included in the genus were mostly previously classified in the genus Polymeridium, while the type species was known by different names in the genus Campylothelium. Phylogenetic analysis showed that the group of species was distant from the core group of their previous genus.[2] An eight species, from Australia, was added to the genus in 2022.[3]
