“…Strepsilin also occurs in L. dibenzofuranica Elix, L. goughensis Elix & Øvstedal and L. multiacida Aptroot (Elix & Tønsberg 2004;Elix et al 2005;Elix & Kalb 2008). Lepraria dibenzofuranica has a powdery, whitish green to greenish or bluish grey thallus containing several dibenzofurans (strepsilin in minor or trace amounts), anthraquinones and fatty acids (Elix & Kalb 2008).…”

“…Lepraria dibenzofuranica has a powdery, whitish green to greenish or bluish grey thallus containing several dibenzofurans (strepsilin in minor or trace amounts), anthraquinones and fatty acids (Elix & Kalb 2008). Lepraria goughensis produces lecanoric and gyrophoric acids and anthraquinones in addition to strepsilin and has a powdery thallus but lacks a hypothallus and medulla (Elix et al 2005). Lepraria multiacida differs in having a stratified and sometimes lobate thallus containing atranorin, the stictic acid complex, consalazinic and salazinic acids, terpenoids, and some other substances in addition to strepsilin Elix & Tønsberg 2004).…”

Two new corticolous lichen species are described, Lepraria nothofagi Elix & Kukwa (atranorin, strepsilin, porphyrilic acid) from Argentina and L. stephaniana Elix, Flakus & Kukwa (4-O-methylleprolomin, zeorin, salazinic acid, unknown terpenoid) from pre-Andean Amazon forest of Bolivia. In addition, the paper presents new records of 16 species of Lepraria from South America. Lepraria adhaerens, and L. diffusa are new to the Southern Hemisphere; L. borealis is new to South America; L. alpina is new to Chile, Colombia, Peru and Venezuela; L. caesioalba (chemotype I) is new to Venezuela, L. lobificans new to Argentina, L. pallida new to Peru, and L. sipmaniana new to Bolivia and Chile. The Chilean records of L. membranacea appeared to belong to L. sipmaniana. Therefore, the number of Lepraria spp. known at present from South America is enlarged to 27 species. 4-O-methylleprolomin is reported for the second time from lichens.

“…The terminology of Lendemer (2011) is used. In South America, 30 species of Lepraria are currently recognized (Flakus & Kukwa 2007; Lendemer 2010; Elix et al 2010; Flakus et al 2011), none of which have the chemical content encountered in the present species. Lepraria species with usnic acid, Lecanora ecorticata J. R. Laundon [syn.…”

Ten new species in nine different genera are described from the Falkland Islands (Islas Malvinas): Bryonora granulata with a finely granular thallus containing perlatolic acid; Bryoria mariensis, a terricolous species with norstictic acid and unusual cortex cells; Carbonea hypopurpurea with a K+ purple hypothecium and a thallus containing confluentic and 2′-O-methylperlatolic acids; Caloplaca megalariicola lichenicolous on Megalaria grossa; Cladonia flammea with a red-orange coloration on the lower side of the primary squamules; Cliostomum falklandicum, on rocks and with a dispersed thallus containing only atranorin; Lepraria malouina with usnic and stictic acids; Rimularia andreaeicola, over bryophytes and lacking lichen substances; R. subpsephota, similar to R. psephota but with a discrete white thallus lacking norstictic acid; and Usnea austrocampestris, a straggling species in sect. Neuropogon from the mountain tops. Rimularia andreaeicola is also known from Tierra del Fuego and R. subpsephota from Tierra del Fuego and South Georgia, but the other species are known only from the Falkland Islands. The new combinations Carbonea agellata, C. subdeclinans, Cliostomum aeruginascens and C. violascens are also made; Lecidea interrupta Darb. and Lecidea protracta Darb. are reduced to synonymy with Lecanora xantholeuca (Müll. Arg.) Hertel; Rhizocarpon simillimum is reported for the first time from the Southern Hemisphere, from the Falkland Islands and New Zealand; and Bryoria chalybeiformis is reported for the first time from the Falkland Islands.
