Linke K., Hemmerich J., Lumbsch H. T. (2003): Identification of Nostoc cyanobionts in some Peltigera species using a group I intron in the tRNALeu gene, Bibl. Lichenol., 86: 113-118

Sequences of a group I intron in the tRNALeu of six Nostoc samples were obtained and aligned with 17 sequences obtained from GenBank. A simple distance based approach, using a neighbor-joining tree with Jukes-Cantor correction, was employed to identify the cultures at species level. The results indicate that Peltigera malacea has at least two different cyanobionts: N. muscorum and N. punctiforme. N. punctiforme is present in P. hydrothyria and N. commune in P. canina Read more...

Diederich P., Sérusiaux E. (2003): Stromatopogon cladoniae sp. nova, a remarkable new lichenicolous coelomycete from Belgium, Bibl. Lichenol., 86: 103-106

The new species Stromatopogon cladoniae sp. nova is distinguished from the type species of the genus by the overall smaller dimensions of galls, pycnidia, macroconidia and microconidia, and by a different host. It is known only from the type locality in the Belgian Ardenne where it grows over Cladonia polydactyla Read more...

Breuss O. (2003): Eine neue Dermatocarpon-Art (lichenisierte Ascomyceten, Verrucariales) aus Kanada, Bibl. Lichenol., 86: 99-102

A new species of the lichen genus Dermatocarpon, D. atrogranulosum, is described. It belongs to sect. Polyrhizion. Its underside is covered by papillate to coarse, irregularly knobby or somewhat elongated rhizinomorphs. Underside and rhizinomorphs bear small complexes of two to several cells with thick, dark brown walls. Thus the underside appears minutely waited or granular. The new species is only known from the type locality in Canada. Lichenized Ascomycetes, pyrenocarpous lichens, Dermatocarpon … Read more...

Braun U. (2003): Miscellaneous notes on some cercosporoid hyphomycetes, Bibl. Lichenol., 86: 79-98

The new species Passalora amazonica, Pseudocercospora euphorbiacearum, P. feigenana, P. graphioides, P. ficina and Stenella are described and the new combinations Cladosporium cheonis, Passalora P. Pseudocercospora amonifolii, P. ilicis and P.pulvinula are introduced. Cercospora cluytiae, C. mucunicola and C. panacis are re-described and their taxonomic positions are discussed Read more...

Aptroot A., Lücking R. (2003): Phenotype-based phylogenetic analysis does not support generic separation of Gyalidea and Solorinella (Ostropales: Asterothyriaceae), Bibl. Lichenol., 86: 53-78

We performed a phylogenetic analysis of the lichen family Asterothyriaceae, using morphological, anatomical, and ontogenetic data. The results support generic status of Psoro- theciopsis and Asterothyrium in their current circumscription, while Gyalidea becomes para- or possibly polyphyletic when including G. epiphylla and G. phyllophila and excluding the monospecific Solorinella as a separate genus. Gyalidea epiphylla and G. phyllophila appear isolated from the remainder of the genus on a clade … Read more...

Leuckert C. & Hertel H. (2003): On the Lecidea atrobrunnea complex (Lecanorales, Lecideaceae) in the Americas. I. Introduction and chemistry, Bibliotheca Lichenologica, 86: 13-31

The lichen chemistry of some 860 mainly North American specimens of Lecidea atrobrunnea (Lam. & DC.) Schaer. sensu lato (inch L. placodiiformis Hue, L. protabacina Nyl., L. subfumosa (Arnold) Zwackh, L. syncarpa Zahlbr.) was studied. Diagnostically significant lichen substances are p-depsides of the orcinol-type with long aliphatic side-chains, depsidones of the ß-orcinol type, and dibenzofurans. 15 different chemotypes are distinguished. Beside 8 single-syndrome chemotypes 6 complex chemotypes … Read more...

Obermayer W. & Elix J.A. (2003): Notes on chemical races in Sulcaria sulcata from southeastern Tibet and adjacent regions, Bibliotheca Lichenologica, 86: 33–46

More than 200 thalli of Sulcaria sulcata (lichenized Ascomycotina) from southeastern Tibet and adjacent regions have been analyzed chemically. Six major chemical races were detected, characterized by the occurrence of the following major compounds: psoromic acid (chemical race 1a), 2-methoxypsoromic acid (2a), 2-hydroxyvirensic acid (3a; often in combination with 2-hydroxyconvirensic acid), virensic acid (3b), and vulpinic acid, the latter in combination with either psoromic acid (1b) or 2-methoxypsoromic … Read more...

Huneck S. (2003): Die wasserabweisende Eigenschaft von Flechtenstoffen, Bibl. Lichenol., 86: 9-12

The hydrophobic property of 37 lichen substances (depsidones, depsides, pulvin lactones, depsones, triterpenes, dibenzofuranes, cycloaliphatics, aliphatic lactones, aliphatic acids, diterpenes, monocyclic aromatics, chromones, xanthones, and anthraquinones) has been compared by a simple test. Most hydrophobic metabolites are depsides and depsidones with n-pentyl side chains Read more...

Elix J. A., Giralt M., Wardlaw J. H. (2003): New chloro-depsides from the lichen Dimelaena radiata, Bibl. Lichenol., 86: 1-7

The new depsides 3-chlorolecanoric acid (1), 3-chloronordivaricatic acid (2), 3- chlorosubdivaricatic acid (3).and 3-chloroisosubdivaricatic acid'(4) have been detected in the lichen Dimelaena radiata and the structure of these metabolites has been established by unambiguous synthesis. The chromatographic and spectroscopic properties of the new depsides are described Read more...
