Søchting U. (2001): Chemosyndromes with chlorinated anthraquinones in the lichen genus Caloplaca, Bibl. Lichenol., 78: 395-404

Eleven chemosyndromes that include the chlorinated anthraquinones 7- chloroemodin and fragilin are described from the genus Caloplaca (Teloschistaceae) based on HPLC analyses of 125 specimens. These are arranged in three syndrome families that are dominated by parietim fragilin and 7-chloroemodin, respectively. Biosynthetic pathways and possible taxonomic implications arc discussed Read more...

Smith C. W. (2001): The lichen genus Umbilicaria in the Hawaiian islands, Bibl. lichenol., 78: 389-394

The genus Umbilicaria is represented by four species in the Hawaiian Islands. Three species formerly considered endemic are placed in synonymy with widely distributed Northern Hemisphere taxa. Thus, U. hawaiiensis is synonomous with U. decussata,while U. magnussonii and U. pacifica are synonymous with U. hirsuta. Two additional species, U. aprina and U. hyperborea, are also present. Hawaiian specimens are most common above 3500 m, all are sterile, and it is suggested that their presence in the Hawaiians … Read more...

Ralston K. (2001): Francis Robert Muter Wilson: pioneer australian lichenologist, Bibl. Lichenol., 78: 369-388

In the nineteenth century, clergymen made a significant contribution to the study of Australian natural history mainly, it can be suggested, because they were highly educated, were usually well versed in Latin, had the opportunity to travel around their parishes and had the leisure time to pursue this study (GILBERT 1982). Coupled with this is the fact that natural history was a very popular pastime of the nineteenth century, and it was often recommended as a cure for various medical ailments. Each … Read more...

Porzel A. & Huneck S. (2001): Acaranoic acid and acarenoicacid: confirmation of structures by modern NMR methods, Bibl. Lichenol., 78: 365-368

The structure and stereochemistry of acaranoic acid and acarenoic acid have been confirmed by modern NMR methods as (-)-2S-methyl-3R-carboxypentadecyl-l—>-5S-olide and (-)- 2-methylene-3R-carboxypentadecyl-l—>S-olide, respectively Read more...

Owe-Larsson B. & Rambold G. (2001): The sorediate species of the lichen genus Miriquidica (Lecanorales, Lecanoraceae), Bibl. Lichenol., 78: 335-364

The morphological and chemical variation and the distribution of Miriquidica intrudens and M. nigroleprosa are described. Lecidea is regarded as a variety of M. nigroleprosa and the new combination M. nigroleprosa var. liljenstroemii is made. A sorediate form of M. complanata is newly described as M. complanata f. sorediata Read more...

Orange A., Wolseley P., Karunaratne V. & Bombuwala K. (2001): Two leprarioid lichens new to Sri Lanka, Bibl. Lichenol., 78: 327-333

A brief account of collections and literature pertaining to the lichens of Sri Lanka is followed by descriptions of Lepraria atrotomentosa Orange & Wolseley sp. nov. and the first Sri Lankan records of Leproloma Kiimmerl. & Leuckert. Lepraria atrotomentosa is also reported from Japan Read more...

Obermayer W. (2001): On the identity of Lethariella sinensis Wei & Jiang, with new reports of Tibetian Lethariella species, Bibl. Lichenol., 78: 321-326

The holotype material of Lethariella sinensis Wei & Jiang is a mixture of two chemically distinct taxa, one containing psoromic acid, the other containing norstictic acid. The former is chosen as lectotype and, as a result, L. mieheana Obermayer becomes a synonym of L. sinensis. Additional Lethariella specimens from Tibet have also been subjected to TLC analysis, and the results are presented Read more...

Nash H. T., Thomas M. A., Hoober J. K., Gries C. & Zheng S. (2001): Free amino acids in lichens and their symbionts, Bibl. Lichenol., 78: 313-319

Free amino acids were analyzed in four macrolichens: Evernia prunastri, Pseudevernia intensa, Flavopuncteliapraesignis and Nephroma resupinatum. Overall concentrations measured fell well within the range of values reported in the literature. Little change in pool size of these amino acids was found in response to sulphur dioxide fumigations. Significant variation among species was observed with the highest values found in the cyanolichen A resupinatum. Species to species variation partly reflected … Read more...

Moberg R. (2001): The lichen genus Physcia in Australia, Bibl. lichenol., 78: 289-311

Seventeen species of the lichen genus Physcia (Schreb.) Mich. (Ascomycotina, Physciaceae) are reported from Australia. One species, P. jackii. Moberg, is described as new, and ten others are recorded for the first time from the continent: P. citrostriata, P. bizicina, P. crispa, P. decorticata, P. nubila, P. phaeocarpa, P. poncinsii, P. sorediata, P. undulata and P. verrucosa. Physcia albo- plumbia is synonymized with P. albata. Some morphological and anatomical characters are assessed, and a key … Read more...
