  • Genus: Dendrographa
  • Family: Roccellaceae
  • Genus: Wadeana
  • Taxonomic Rank: Species
  • Informal Taxonomy: Fungi/Lichens - Lichens

Nomenclature and Synonyms

  • Dendrographa conformis (Tehler) Ertz & Tahler.
  • Dendrographa latebrarum (Ach.) Ertz & Tehler has the synonym Lichen latebrarum Ach.
  • Wadeana dendrographa (Nyl.) Coppins & P. James has the synonym Lithographa dendrographa Nyl.

Distribution and Habitat

  • Dendrographa leucophaea has been found in Mexico and California (e.g., Point Lobos State Park, Monterey Co., San Clemente Island).
  • Wadeana dendrographa is found on rough, nutrient-rich bark in wood-pasture and parkland, particularly in lowland areas. Mentions of Dorset and Breconshire also appear.
  • Dendrographa franciscana

Genetic Information

  • Studies have sequenced the internal transcribed spacers (ITS) of the nuclear ribosomal DNA for Dendrographa leucophaea to analyze sterile and fertile specimens.

Interactions with Other Organisms
