Description
The relevant characters of the genus Bryostigma are provided under Bryostigma muscigenum.
Remarks
Bryostigma has been included in Arthonia until recently. Based on molecular systematic studies, it has been accepted as independent genus by Frisch et al. (2014). Several species with a morphology similar to B. muscigenum are still kept in the genus Arthonia for taxonomic stability, pending a much-needed revision of this lineage of the Arthoniaceae.
