Taxonomy: Misidentified as D. luridum in western North America until 2004. Based on ongoing molecular study (Bruce McCune, unpub.), D. meiophyllizum does not occur in western North America; lichens identified as D. meiophyllizum in CA may be an existing, undetermined Dermatocarpon sp. or a novel taxon. Dermatocarpon meiophyllizum is a placeholder with 2B status until a new name or combination becomes available. |
