Hertelidea

Hertelidea is a genus of crustose lichens in the family Stereocaulaceae. Characteristics of the genus include carbon-black ring or outer margin (exciple) around the fruit body disc (apothecium), eight-spored, Micarea-type asci and mostly simple, hyaline ascospores that lack a transparent outer layer. Hertelidea species mostly grow on wood, although less frequently they are found on bark or soil. While the type species, Hertelidea botryosa, has a widespread distribution, most of the other species are found only in Australia.

==Taxonomy== Hertelidea was circumscribed in 2004 by Christian Printzen and Gintaras Kantvilas to accommodate species that were formerly referred to as the "Lecidea botryosa" group. Four species were originally included: Hertelidea botryosa, H. eucalypti, H. geophila, and H. pseudobotryosa. H. aspera was transferred to the genus from Lecidea in 2005, while H. wankaensis was described as a new species in 2006.
