There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products (i.e., secondary metabolites made by lichens) are importan ...

Hertelidea
''Hertelidea'' is a genus of crustose lichen Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichen ...s 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 ascus, asci and mostly simple, hyaline ascospores that lack a transparent outer layer. ''Hertelidea'' species mostly lignicolous lichen, 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 circumscription (taxonomy), circumscribed in 2004 by Christian Printzen and Gintaras Kantvilas to accommodate species that were formerly ref ...

Xyleborus (lichen)
''Xyleborus'' is a small genus of lichen-forming fungi in the family Stereocaulaceae. It comprises two species. The genus was circumscribed in 2009 by Richard C. Harris and Douglas Ladd with '' Xyleborus sporodochifer'' assigned as the type species. A second species, '' X. nigricans'', was added to the genus in 2015. This genus is only found in North America, in the Ozarks, the Appalachians, and the Mid-Atlantic Coastal Plain. ''Xyleborus'' species only grow as a crust with black apothecia on weathered logs and stumps in intact forests. Taxonomy ''Xyleborus'' was erected in 2007 by Richard C. Harris and Douglas Ladd after they encountered an unusual crustose lichen with abundant white on seasoned oak logs in the Ozark Highlands. They treated that species, ''X. sporodochifer'', as the type and sole member of a new genus distinguished by its '' Micarea''-type asci, lignicolous habit, and conspicuous sporodochial cushions, all rare features among crustose lichens.

Boreal Ecosystem
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd, and Dwd. Boreal ecosystems are some of the most vulnerable to climate change. Both loss of permafrost, reductions in cold weather and increases in summer heat cause significant changes to ecosystems, displacing cold-adapted species, increasing forest fires, and making ecosystems vulnerable to changing to other ecosystem types. These changes can cause Climate change feedback cycles, where thawing permafrost and changing ecosystems release more greenhouse gas emissions into the atmosphere causing more clima ...

Lecanoromycetes Families
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence.

Catalog Of Life
The Catalogue of Life (CoL) is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, ''Encyclopedia of Life'', and the Global Biodiversity Information Facility. The Catalogue currently compiles data from 165 peer-reviewed taxonomic databases that are maintained by specialist institutions around the world. the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time.
