Notes on the Lichen Genus Leptogium (Collemataceae, Ascomycota) in South Korea
Mycobiology, 2014
Leptogium (Ach.) Gray is distributed throughout South Korea; however, for nearly two decades no detailed taxonomic or revisionary research on this lichen genus has been conducted. This study examined the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and samples were identified using descriptions recently published in the scientific literature. In this revisionary study, a total of fourteen species of Leptogium were documented, including new records of Leptogium delavayi Hue, Leptogium denticulatum Nyl., and Leptogium trichophoroides P. M. Jørg. & A. K. Wallace. Detailed descriptions of each species are given, including their morphological, anatomical, and chemical characteristics. A key to all Leptogium species known to occur in South Korea is also presented.
The lichen genus Lepraria (Stereocaulaceae) in South Korea
Mycotaxon, 2010
The species belonging to lichen genus Lepraria that occur in South Korea are revised. Seventeen taxa are accepted. Brief descriptions of the species and a key to the taxa are provided. All species described here except L. coriensis are new to South Korea. Among them, L. caesiella, L. eburnea, L. leprolomopsis, L. lobata, L. pallida, L. texta and L. xerophila are reported for first time from eastern Asia (including China and Japan).
Two new species and a new record of Lecanora sensu stricto (Lecanoraceae, Ascomycota) from India
Phytotaxa , 2012
The new species Lecanora girigangaensis and L. upretii from Himachal Pradesh in India are described. The former has large apothecia with a constricted base, melacarpella-type amphithecium, glabrata-type epihymenium, hyaline hypothecium, and contains atranorin and usnic acid, while the latter is characterized by having yellow-brown to pale brown apothecial discs, a melacarpella-type amphithecium, pulicaris-type epihymenium, and contains atranorin and usnic acid. Also, Lecanora subalbellina is recorded from Asia for the first time.
A new species of Graphis (lichenized Ascomycetes) from South Korea
Mycotaxon, 2010
Graphis flavopalmicola is described as a new lichenized fungus from Jeju Island (South Korea). It is characterized by smooth, whitish-gray, UV+ pale yellow thallus (lichexanthone), unbranched to irregularly branched lirellae; completely carbonized exciple, and transversely 5-9-septate ascospores. It differs from the closely related G. palmicola chiefly in its chemistry; the latter has no substances and is UV-. 80013-X Elix JA, Johnston J, Parker JL. 1987.

Additions to the genus Lecidella (lichenised Ascomycetes: Lecanoraceae)
Two new taxa in Lecidella Körb. are described: L. leucomarginata Kantvilas & Elix, from Kangaroo Island (South Australia) and southwestern Western Australia and L. granulosula var. lecanorina Kantvilas & Elix, from Kangaroo Island (South Australia) and the coast of southern New South Wales. Both display the unusual feature of an unpigmented proper excipulum, densely inspersed with crystals. A key to Lecidella in temperate Australia is presented.
Status of some poorly known lichen species from the genus Lecanora (lichenized Ascomycota) in Poland
Mycotaxon, 2010
Taxonomic and chorological notes on four Lecanora species, misidentified or poorly known in Poland, are presented. L. aitema is reported from Poland for the first time; its status and previous reports in the country are discussed. L. phaeostigma, practically known only from historical publications, appears to be quite frequent in the Polish Carpathians. The current status of poorly known L. ramulicola is presented here based on revised literature and herbarium data. No specimen of L. cadubriae has been confirmed in Polish collections and all reports of this species from Poland, in fact, refer to L. ramulicola. Because of the misidentifications and nomenclatural confusion, L. cadubriae should be excluded from the list of Polish lichens. The taxonomy, nomenclatural remarks, chemistry, habitat requirements, and distribution of all taxa are discussed.

During a revision of epiphytic species of theLecanora subfuscagroup in the Czech Republic, nine taxa were recorded.Lecanora cinereofusca, although reported for the first time from the country here, is considered to be extinct, as isL. horiza. Lecanora circumborealishas been excluded from the list of Czech lichens.Lecanora rugosellaandL. subrugosarespectively are regarded as extreme morphological forms ofL. chlaroteraandL. argentata, ecologically derived through nutrient enrichment (eutrophication).Lecanora laevisis regarded as a morphotype ofL. horiza. An identification key is provided. The importance of the amphithecium and cortex type as taxonomic characters is discussed in detail. Several new secondary metabolites belonging to the terpenoids, discovered during an investigation of lichen compounds, proved to be taxonomically important. The abundance ofL. allophanaandL. chlaroterahas decreased during the second half of the 20th century, butL. pulicarishas expanded. The main reasons...

Lecanora stainislai is characterized by a very thin sorediate thallus, forming a more or less continuous layer of soredia and by the production of usnic acid and zeorin. It usually grows on smooth bark of trees in forests and is known from the Czech Republic, Norway, Poland, Russia, Ukraine and western North America (Canada, USA). It is chemically similar to the sorediate L. compallens, which however has an episubstratal thallus in non-sorediate parts and often delimited soralia. They have also different phylogenetic positions within the L. symmicta group. Moreover, based on molecular marker analysis the position of L. expallens is resolved within this group for the first time.
