Abstract This paper presents new distribution records for 80 lichen taxa from Bolivia, including 14 new national records: Bulbothrix thomasiana Benatti & Marcelli, Dirinaria confluens (Fr.) Awasthi var. coccinea (Lynge) Awasthi, D. melanocarpa (Müll. Arg.) C. W. Dodge, Gyalideopsis lambinonii Vězda, Malmidea sulphureosorediata M. Cáceres, D. A. Mota & Aptroot, Parmelia warmingii Vain., Ramalina aspera Räsänen, R. canaguensis V. Marcano & A. Morales, R. disparata Krog & Swinscow, R. grumosa Kashiw., R. incana Kashiw., R. puiggarii Müll. Arg., R. usnea (L.) Howe and Ramonia valenzueliana (Mont.) Stizenb. Notes on distribution and chemistry are provided for most species.
New species and records ofLepraria(Stereocaulaceae, lichenized Ascomycota) from South America
(Cambridge University Press, 2010) Adam Flakus; John A. Elix; Pamela Rodriguez‐Flakus; Martin Kukwa
Abstract 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.
Notes on the lichen genus Ochrolechia in Bolivia
(Władysław Szafer Institute of Botany, 2013) Martin Kukwa; Pamela Rodriguez‐Flakus; Adam Flakus
Abstract The paper presents new records for four taxa of Ochrolechia A. Massal. from Bolivia, of which three, O. austroamericana (Räsänen) Räsänen, O. subpallescens f. Verseghy uruguayensis Verseghy and O. upsaliensis (L.) A. Massal., are new for the country. Ochrolechia subpallescens f. uruguayensis is shown to differ chemically from O. subpallescens s.str., but its taxonomic rank needs to be clarified with molecular studies. Ochrolechia africana Vain. is also reported for the first time for Tanzania and Uruguay, and O. austroamericana for Ecuador.
Revision of the GeneraCetreliaandPunctelia(Lecanorales, Ascomycota) in Lithuania, with Implications for their Conservation
(Q15792988, 2012) Martin Kukwa; Jurga Motiejūnaitė
Kukwa, M. & Motiejūnaitė, J. 2012. Revision of the lichen genera Cetrelia and Punctelia (Lecanorales, Ascomycota) in Lithuania with implications for their conservation. — Herzogia 25: 5 –14.A revision of all available specimens has shown that the genus Cetrelia in Lithuania is represented by two species, C. monachorum and C. olivetorum. One specimen belonged to Punctelia jeckeri. The distribution and status of both genera in Lithuania are reviewed, distribution maps are provided, and the merits of the segregates for conservation measures are discussed. Cetrelia monachorum and Punctelia jeckeri are reported for the first time from Lithuania and from the Baltic states.
