H. aspera H. botryosa H. eucalypti H. geophila H. pseudobotryosa H. wankaensis Hertelidea is a genus of crustose lichens in the family Stereocaulaceae.
Hertelidea was circumscribed in 2004 by Christian Printzen and Gintaras Kantvilas to accommodate species that were formerly referred to as the "Lecidea botryosa" group.
[3] The genus name honours Hannes Hertel (b.1939), a German Taxonomist and lichenologist and former Director of the Botanische Staatssammlung München,[4] who was the subject of the Festschrift in which this species was published.
Their apothecia, which are often arranged in conspicuous clusters, are lecideine, meaning that they have a carbonized thin black ring (an exciple) around the cup-shaped apothecium.
The asci are eight-spored and Micarea-like, featuring a prominent, amyloid thallus that is more or less lacking an ocular chamber but is pierced by a more darkly staining tubular structure.
