S., Kubiak D., Kukwa M., Kuznetsova E., Leppik E., Lõhmus P., Prigodina Lukošienė I., Pykälä J., Stončius D., Stepanchikova I., Suija A., Thell A., Tsurykau A., Westberg M., 2012: Lichens, lichenicolous and allied fungi found in Asveja Regional Park (Lithuania) [Kerpės, lichenofiliniai ir kerpėms artimi saprotrofiniai grybai Asvejos regioniniame parke]. - Bot. Lith., 18(2): 85-100. The paper reports the results of lichenological investigations in Asveja Regional Park (eastern Lithuania). A large part of the study was performed during the joint 18th Symposium of the Baltic Mycologists and Lichenologists (BMLS) and Nordic Lichen Society (Nordisk Lichenologisk Förening, NLF) meeting on 19-23 September 2011. A list of 259 species is presented. Of these, 30 species are new to Lithuania. Arthonia helvola, Bacidina sulphurella, Candelariella lutella, Catillaria croatica, Cladonia conista, Gyalecta derivata, Lecanoraquercicola, Leptosphaeria ramalinae, Strigula jamesii, Trichonectria rubefaciens, Verrucaria banatica, V. boblensis, V. christiansenii, V. illinoisensis, V. inornata, V. nigrofusca, V. trabicola, Zwackhiomyces diederichii were recorded for the first time in the Baltic countries. New lichens to Lithuania are as follows: Bacidiaincompta, Caloplaca crenulatella, C. pyracea, Catinaria atropurpurea, Lecanora populicola, L. semipallida, Mycobilimbia epixanthoides, Ramalina dilacerata, Verrucaria inaspecta, and new lichenicolous fungi are: Cladosporium licheniphilum, Stigmidium microspilum, Xenonectriella leptalea. Eighteen species included in the Lithuanian Red Data Book were recorded, which is the highest number known for any studied area in Lithuania.

Contrasting pattern of photobiont diversity in the Atlantic and Pacific populations of Erioderma pedicellatum (Pannariaceae)

The present study investigates the photobiont diversity of the boreal felt lichen, Erioderma pedicellatum . Previously sampled genetic data from Newfoundland were reanalyzed and new sequence data (16S rDNA, rbcLX ) of the boreal felt lichen from Alaska (USA), Kamchatka (Russia), and North Trondelag (Norway) were generated. The highest genetic diversity of the photobiont is found in Alaska and Kamchatka, indicating that these may be the primary sources of the species in the Northern Hemisphere. In Newfoundland, the photobiont of E. pedicellatum was screened on leaves of the symbiotic liverwort Frullania asagrayana and it was found to occur on trees where no other lichens were present, demonstrating that the geographical distribution, and possibly also the ecological requirement of the photobiont of E. pedicellatum , is wider than that of the lichen phenotype. Finally, a postulated association between the occurrence of the vegetatively reproducing Coccocarpia palmicola and the occurrence of the compatible photobiont of E. pedicellatum on the same tree could not be established.

Ninety-one species of lichens and allied fungi new to Latvia with a list of additional records from Kurzeme

A., Kubiak, D., Kukwa, M., Moisejevs, R., Stepanchikova, I., Suija, A., Tagirdzhanova, G., Thell, A. & Tsurykau, A. 2016. Ninety-one species of lichens and allied fungi new to Latvia with a list of additional records from Kurzeme. — Herzogia 29: 143–163. The results of lichenological excursions of the 19th Symposium of Baltic Mycologists and Lichenologists (BMLS) in Latvia, Kurzeme region, 22–26 September 2014, are reported. A list of 290 species is presented, of which 238 are lichenized, 43 lichen-inhabiting, and nine saprotrophic fungi: ninety-one species are new to Latvia, twelve of which (Caloplaca duplicata, Cresporhaphis wienkampii, Ellisembia lichenicola, Gallowayella weberi, Gregorella humida, Lichenochora weillii, Parmelia serrana, Polycauliona phlogina, Reconditella physconiarum, Stictis brunnescens, Thelocarpon superellum, and Verrucaria tectorum) are also new for the Baltic States. Athallia alnetorum is reported here for the first time in northern Europe. The presence of Ochrolechia androgyna s. str., Athallia holocarpa and A. pyracea is confirmed for Latvia, and Parmelia submontana is reported as a new host for Homostegia piggotii.

Contribution to the Study of Umbilicariaceae (Lichenized Ascomycota) in Russia. II. Kamchatka Peninsula

Abstract: n Davydov, E. A., Himelbrant, D. E. & Stepanchikova, I. S. 2011. Contribution to the study of Umbilicariaceae (lichenized Ascomycota) in Russia. II. Kamchatka Peninsula. — Herzogia 24: 251–263. Two species of Lasallia and 14 of Umbilicaria with one additional variety are reported from the Kamchatka Peninsula. Of these, Lasallia pennsylvanica, Umbilicaria aprina, U. cinereorufescens, U. decussata, U. hirsuta, U. hyperborean var. radicicula and U. rigida are new for the Kamchatka Peninsula. Previous reports of Umbilicaria formosana, U. leiocarpa, U. muehlenbergii, U. polyphylla, U. spodochroa and U. virginis are considered to be doubtful for Kamchatka. The lectotype of Gyrophora hyperborea f. sublaevigata Savicz was designated.

Lichen Diversity on Carbonate Stone Substrates in St. Petersburg, Russia: A Review

The review of published records of lichens on carbonate stone substrates (marbles, limestones, limestone tufa, and concrete) in Saint Petersburg has been presented. Altogether, 66 species of lichens from 35 genera and 16 families have been found in more than 40 papers. The most diverse genera are Verrucaria, Physcia, and Lecanora. Most of the species inhabiting carbonate stone materials in Saint Petersburg form episubstratic thalli, only the species of genus Verrucaria, often have endolithic or mostly endolithic thalli and could cause pitting of carbonate materials. Other lichen inhabitants of these substrates could be agents of substrate piling. The majority of taxa were not reported in Saint Petersburg from natural carbonate materials (marbles, limestones, or limestone tufa), but only from concrete; species inhabiting exclusively carbonate stones in Saint Petersburg are very few; lichens strictly confined to natural carbonate substrates are almost absent.
