Multivariate analysis of anatomical characters confirms the differentiation of two morphologically close species, Melanohalea olivacea (L.) O. Blanco et al. and M. septentrionalis (Lynge) O. Blanco et al.
TLDR
These characters proved to be powerful in identifying specimens with a poorly-developed morphology and confirmed the presence of M. olivacea in Switzerland.
Global distribution of the European species of the lichen genus Melanelia Essl.
Aim  The global distribution of the European species of Melanelia Essl. (Lichenes: Parmeliaceae) was investigated in order to understand their distribution patterns against the background of

The lichens of the northern shore of the Gulf of Finland in the limits of St. Petersburg, Russia – diversity on the edge of the megapolis
We present a lichen checklist for the northern shore of the Gulf of Finland in the limits of St. Petersburg, Russia. This area has diverse lichen biota within the city limits, and has been
The brown parmelioid lichen species in Greenland
Sixteen species of brown parmelioids are reported from Greenland, including one species of Cetrariella, three species of Melanelia, two species of Melanelixia, six species of Melanohalea, and four
CATALOG OF LICHENS, LICHENICOLES, AND ALLIED FUNGI IN CALIFORNIA (second revision)
This second revision of the California lichen catalog reports 1,869 taxa at species level and below (of which 58 are recognized at the level of variety, subspecies, or forma) for the state, an
Miocene and Pliocene dominated diversification of the lichen-forming fungal genus Melanohalea (Parmeliaceae, Ascomycota) and Pleistocene population expansions
TLDR
Diversification within Melanohalea occurred predominantly during the Miocene and Pliocene, although estimated of divergence times differed by up to 8.3 million years between the two methods, which indicates that, in some cases, taxonomically diagnostic characters may be maintained among divergent lineages for millions of years.
Generic concepts in parmelioid lichens, and the phylogenetic value of characters used in their circumscription
TLDR
It is concluded that characters related to thallus form or chemical products prove to be less informative at the generic level than has sometimes been assumed.
