Coppinsiella and Seawardiella – two new genera of the Xanthorioideae (teloschistaceae, lichen-forming ascomycota)
The genera Coppinsiella and Seawardiella are described based on the combined phylogenetic analysis from ITS nrDNA, 28S nrLSU and 12S mtSSU sequences. The affinities of the new genera Orientophila, Athallia, Flavoplaca and Calogaya are discussed. The former Caloplaca lobulata group (or ‘Xanthoria lobulata-Gruppe’ sensu Steiner et Poelt 1982) found to be positioned in the Calogaya clade based on ITS phylogeny while after a three gene phylogeny (based on ITS nrDNA, nrLSU and mtSSU sequences) two species (i.e.: Seawardiella lobulata and described as new S. tasmaniensis) were located in the Seawardiella clade of the Xanthorioideae. Three other species (i.e. Lazarenkoella zoroasteriorum, L. persica and L. polycarpoides) were positioned in the Lazarenkoella-clade of the Brownlielloideae. The position of all species of the Calogaya clade (after ITS phylogeny) should be re-evaluated based on three gene phylogeny from ITS nrDNA, nrLSU and mtSSU sequences. The new species Seawardiella tasmaniensis is described, illustrated and compared with closely related taxa.
New combinations are suggested for eight taxa (i.e. Athallia inconnexa (for Lecanora inconnexa Nyl.), Calogaya safavidiorum (for Caloplaca safavidiorum S. Y. Kondr., in Kondratyuk et al.), Coppinsiella orbicularis stat. et comb. nov. (for Caloplaca substerilis subsp. orbicularis M. Haji Moniri, Vondrák et Malíček), Coppinsiella substerilis (for Caloplaca substerilis Vondrák, Palice et van den Boom, in Vondrák et al.), Coppinsiella ulcerosa (for Caloplaca ulcerosa Coppins et P. James), Lazarenkoella persica (for Xanthoria polycarpoides var. persica J. Steiner); Lazarenkoella polycarpoides (for Xanthoria polycarpoides J. Steiner), and Seawardiella lobulata (for Lecanora lobulata Flörke))
Brownlielloideae, a new subfamily in the Teloschistaceae (Lecanoromycetes, Ascomycota)
Brownlielloideae, a new subfamily in the Teloschistaceae, is proposed based on phylogenetic analyses of nuclear ribosomal DNA and 12S SSU mitochondrial DNA sequences. The data indicates that the new subfamily includes eight genera, i.e. Brownliella, Marchantiana and six new genera proposed here, Lazarenkoella, Raesaeneniana, Streimanniella, Tarasginia, Tayloriella and Thelliana. Lecanora kobeana Nyl. is lectotypified and shown to be an older name for the type species of the genus Brownliella, B. aequata. In addition, a seventh new genus, Neobrownliella is proposed in the subfamily Teloschistoideae. This new genus and the new species, Thelliana pseudokiamae are described. 13 new combinations are proposed: Brownliella kobeana, Fulgogasparrea appressa, Lazarenkoella zoroasteriorum, Neobrownliella brownlieae, N. montisfracti, Raesaeneniana maulensis, Streimanniella burneyensis, S. kalbiorum, S. michelagoensis, S. seppeltii, Tarasginia tomareeana, T. whinrayi and Tayloriella erythrosticta
Hosseusiella and Rehmanniella, two new genera in the Teloschistaceae
Two new genera in the subfamily Teloschistoideae (Teloschistaceae, Teloschistales) are described: Hosseusiella S. Y. Kondr., L. Lőkös et A. Thell for the Caloplaca chilensis group including three South American species and Rehmanniella S. Y. Kondr. et J.-S. Hur for the new species, R. wirthii S. Y. Kondr. from South Africa. The new genera are supported by a three-gene phylogeny based on ITS1/ITS2 nrDNA, 28S nrLSU, and 12S mtSSU sequences. The new taxonomic position of Elixjohnia ovis-atra in the subfamily Teloschistoideae is discussed. The two new species Hosseusiella gallowayiana and Rehmanniella wirthii are described, illustrated and compared with closely related taxa. Hosseusiella gallowayiana is recorded for the first time as the host for the lichenicolous fungus Arthonia tetraspora S. Y. Kondr. A key to the species of Hosseusiella is included, as well as new information of the related genus Follmannia. The following new combinations are proposed: Hosseusiella chilensis (Kärnefelt, S. Y. Kondr., Frödén et Arup) S. Y. Kondr., L. Lőkös, Kärnefelt et A. Thell, Hosseusiella pergracilis (Zahlbr.) S. Y. Kondr., L. Lőkös, Kärnefelt et A. Thell and Elixjohnia ovis-atra (Søchting, Søgaard et Sancho) S. Y. Kondr
Two closely related species of <i>Caloplaca</i> (Teloschistaceae, Lichenes) from the Namib Desert
The anatomical and reproductive adaptations of two closely related lichen species. Caloplaca elegantissima (Nyl.) Zahlbr. and C. namibensis Karnef., sp. nov., occurring in the outer Namib fog desert, are discussed. Both species belong to the cmstose forms, frequently found in the remarkably rich lichen communities, which largely depend on fog precipitation for their water supply. Both species are endemic to the Namib Desert. They are mainly distributed in South West Africa/Namibia but also extend into south-western Angola. The asexual isidiate species. C. namibensis Karnef., is described as new
