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 records of Lecanora for Bolivia
(Mycotaxon Publications, 2013) Lucyna Liwa; Karina Wilk; Pamela Rodriguez‐Flakus; Adam Flakus
Lecanora cavicola , L. laxa , L. stenotropa, and L. subaurea are reported as new to South America, and L. flowersiana and L. semipallida as new to Bolivia. Distributions of the species are discussed and information on their chemistry and diagnostic characters are provided.
New species and records of<i>Lepraria</i>(<i>Stereocaulaceae</i>, 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.
Phylogenetic placement of Leptosphaeria polylepidis, a pathogen of Andean endemic Polylepis tarapacana, and its newly discovered mycoparasite Sajamaea mycophila gen. et sp. nov.

Abstract Polylepis tarapacana forms one of the highest-altitude woodlands worldwide. Its populations are experiencing a decline due to unsustainable land-use practices, climate change, and fungal infection. In Sajama National Park in Bolivia, Polylepis tarapacana is affected by a disease caused by the pleosporalean fungus Leptosphaeria polylepidis , recently described in 2005. In this study, the integrative morphological and molecular analyses using sequences from multiple DNA loci showed that it belongs to the genus Paraleptosphaeria (Leptosphaeriaceae, Pleosporales). Accordingly, the appropriate new combination, Paraleptosphaeria polylepidis , is made. Pseudothecia of Pa. polylepidis were found to be overgrown by enigmatic conidiomata that were not reported in the original description of this fungus. Morphological and molecular analyses using sequences from two DNA loci revealed that they belong to an undescribed genus and species in the family Dictyosporiaceae (Pleosporales). The new generic and specific names, Sajamaea and S. mycophila , are introduced for this unusual fungus.
