World survey of the genusLepraria(Stereocaulaceae, lichenized Ascomycota)

Abstract

A comparative review of 57 Lepraria species and 2 varieties is provided together with species descriptions and a key. Lecanora leuckertiana is transferred to Lepraria. In addition some putative taxa by different authors are discussed.

The genus Lepraria (Stereocaulaceae, lichenized Ascomycota) in Belarus

“…L. eburnea has been reported from Europe, Asia, North America (including Greenland) and Australia (Güvenç and Oztürk, 1999;Saag et al, 2009;Lendemer, 2013;McCarthy, 2015).…”

“…is "the most unusual member" of the sterile lichen crusts. This genus is comprised of c. 60 species with a leprose thallus almost entirely composed of soredia (Saag et al, 2009). These taxa are diverse both chemically and morphologically.…”

Terricolous lichens as indicator of anthropogenic disturbances in a high altitude grassland in Garhwal (Western Himalaya), India

“…Lichens were identified at the species level using a stereomicroscope and light microscope morpho-anatomically, using relevant keys and monographs (Ahti 2000;Awasthi 2007;Saag et al 2009) and chemically with the help of spot tests, UV light and standardized thin-layer chromatography (Elix et al 1993; Table 1 for abbreviations). Orange et al 2001).…”

Chrysothrix flavovirens, Lepraria elobata, and Ochrolechia arborea new to Portugal

“…The chemical constitution of C. flavovirens (Elix & Tønsberg 2004, Laundon 1981, Tønsberg 1992) is variable, as Elix & Kantvilas (2007) refer to the presence of barbatic and conrhizocarpic acids, as well as epanorin, and the absence of atranorin in samples from the United Kingdom and Sweden. Tønsberg This species develops a diffuse, leprose, predominantly non-lobed and nonstratified, bluish-grey thallus, without medulla and with profuse more or less continuous fine soredia (Saag et al 2009, Tønsberg 1992. Our sterile material of L. elobata contained atranorin, zeorin and stictic acid with satellites.…”

“…Lepraria elobata is morphologically similar to L. caesiella R.C. Harris and L. incana (L.) Ach., which are differentiated chemically by the content in atranorin and zeorin, and divaricatic acid and zeorin, respectively (see Saag et al 2009). Neither species has been found so far epiphytic on pine at Dunas de Quiaios.…”
