INTRODUCTION: Lichens widely occur all over the world and are known to produce unique secondary metabolites with various biological activities. OBJECTIVE: To develop high-throughput screening approaches requiring little to no sample preparation to alleviate the dereplication holdup and accelerate the discovery workflow of new structures from lichens. METHODOLOGY: The extracellular distribution of lichen metabolites is incentive for in situ chemical profiling of lichens using the ambient mass spectrometry DART-MS...

Photosynthesis was compared in two cyanobacterial lichens (Lobaria hallii and Peltigera praetextata) and two green algal lichens (Lobaria pulmonaria and Peltigera leucophlebia) exposed to red, green or blue light. Cyanolichens had substantially lower photosynthetic CO(2) uptake and O(2) evolution than the green algal lichens in blue light, but slightly higher photosynthesis in red and green light. The effective quantum yield of photosystem (PS) II (Φ(PSII)) decreased with increasing red and green light for all species, but in blue light this response occurred in green algal lichens only...

A list of 128 taxa (127 species) of lichens, 6 species of lichenicolous fungi and 2 non-lichenized fungi traditionally included in lichenological literature from the virgin forest Rajhenavski Rog and its surroundings in the southeastern part of Slovenia is presented. The lichen Gyalecta derivata, the lichenicolous fungus Homostegia piggotii, and the non-lichenized fungus Mycomicrothelia pachnea are new to Slovenia. The lichenized fungi Chaenotheca trichialis, C. xyloxena, Lecanactis abietina, Lecanora thysanophora, Pertusaria ophthalmiza, the lichenicolous fungi Monodictys epilepraria, Tremella hypogymniae, Taeniolella friesii, and the non-lichenized fungus Chaenothecopsis pusilla are new to the Dinaric phytogeographical region of Slovenia...

The catalogue is based on a comprehensive evaluation of 152 published sources. It includes 624 species (with 4 subspecies and 13 varieties) of lichenized and 17 species of lichenicolous Ascomycota, as well as 9 non-lichenized Ascomycota traditionally included in lichenological literature.

The catalogue is based on a comprehensive evaluation of 169 published sources. The lichen mycota as currently known from Montenegro includes 681 species (with eight subspecies, nine varieties and one form) of lichenized fungi, 12 species of lichenicolous fungi, and nine non-lichenized fungi traditionally included in lichenological literature.

Experimental methods in lichenology are summarized, the most attention being paid to the synthetic and cultural methods. Synthetic methods are based on the several stages: induction of dissociation of the natural lichen thallus to the monocultures of symbionts, culturing of these symbionts, and subsequent resynthesis under controlled conditions. Synthesis of the model association is based on monocultures of one of the symbionts and free-living organisms. These methods allow studying specificity and selectivity of interactions among symbionts, morphogenesis of the lichen thallus, and the role of minor components of the symbiotic system...

'Sporidesmium' lichenicola sp. nov. is described from the decaying thallus of an unidentified Leptogium species growing on unidentified tree bark from the Guaramacal National Park in Boconó, Táchira, in western Venezuela. This is only the second lichenicolous species to be described under this generic name, and differences from that species and similar species in Sporidesmium s. lat. are discussed. A more precise generic placement will have to await a molecularly based taxonomy of the genus. The original material comes from a mycologically little explored region of the country, and brief information on previous mycological (including lichenological) studies in the area is provided for the first time in English...

Fifty-six species in 36 genera of macrolichens are reported from the Zhongdian area, northwest Yunnan, China during the lichenological expedition for highland macrolichen survey in June, 2004. More than 60% of these species have not been reported in South Korea. All of the 182 collected specimens are deposited in the Korean Lichen Research Institute (KoLRI) at Sunchon National University in Korea, and some of them are duplicated in the lichen herbarium, Crytogamic Herbarium, Kunming Institute of Botany, Academia Sinica (KUN-L) in China...

After an overview on the temporary situation of the lichenology in South Korea, localities of 95 macrolichen taxa are reported for South Korea. In this revised lichen flora of South Korea, 16 species are apparently new to the territory. Voucher specimens have been deposited in the Korean Lichen Research Institute (KoLRI) at Sunchon National University in Korea, and duplicates have also been donated to the National History Museum and Institute, in Chiba, (CBM) Japan.

Lichens are symbiotic organisms associating an heterotrophic fungal host and algal and/or cyanobacterial cells as the photoautotrophic partner. This type of symbiosis is unique. The study of lichens with cellular and molecular biology techniques has made significant contributions to our knowledge of this exceptional symbiosis and stimulates further interest in lichenology.

A brief historical account on the Hungarian lichenology is given in three stages. The early stage involves the oldest collections and the lichenological activity of F. Hazslinszky. In the mid-stage a separate, independent lichen collection was established in the Natural History Museum, and a rapid development of floristical and taxonomic research took place. Recent lichenological research in Hungary follows several fields: taxonomy, biogeography, bioindication and ecophysiology.
