2A-2-P Lichen: from genome to ecosystem in a changing world (2A-2-P5) Submission ID: IAL0073-00001 SPECIES OF GENERA PARMELIA IN RUSSIAN FAR EAST Chabanenko S. I. 1 1 Russian Academy of Science, Sakhalin Botanical Garden, Yuzhno-Sakhalinsk, Russia Genera Parmelia is presented in the south of Russian Far East by 14 species. Preliminary revision species in herbariums of the Far East (TIG, BGI, SAKH), and also LE (St.-Petersburg) has revealed a number of species which require revision. Morphological variability such species differ: P. fertilis, P. adaugescens. Last we will well distinguish only at presence apothecia since has large disputes with a thick cover. P. fertilis at well developed and plentiful apothecia always has poorly developed spoors. Thus the size and the form of lobes, presence adventives lobules, the size and the form pseudocyphellae vary at different samples. Stables morphological signs differ P. omphalodes, P. praesquarrosa, P. saxatilis. P. squarrosa exists in two morphological forms. Some samples have well developed marginal and laminal isidia, pseudocephellae form more less developed network. Other samples differ more extended, linear lobes, with poorly developed laminal pseoducyphellae (they are only for tops of lobes). Lobes plane to slightly concave. The tendency for isidia to be concentrated along the lobe margins. Isidia cylindrical to coralloid and longer, than at the form 1. Samples P. laevior also it is presented by 2 forms. There is a classical form linear lobe to 3 mm in width more often. On an island of Shikotan (Sakhalin District) the form with shorter and wide, tiled leaning lobes and thick cortex has been met. Apothecia are plentiful at two forms; the size dispute does not differ. Samples P. sulcata in the Far East with squarrosely rhizines and with marginal soredia. Laminal soredia thus are absent or are extremely rare. There are samples at whom the medulla C+ turns yellow, at others C –. P. marmarisa, P. isidioclada, P. pseudolaevior, P. fraudans – rare lichens on south part of Russian Far East; it is necessary more quantity of samples to analyze these species. Thus the preliminary data has shown that some species of genera Parmelia from Russian Far East need in analysis using molecular, morphological and chemical characters. (2A-2-P6) Submission ID: IAL0129-00003 THE SPECIES OF CETRARIA ACULEATA GROUP (PARMELIACEAE) IN UKRAINE: IDENTIFICATION PROBLEMS Nadyeina O. V. 1 , Lutsak T. V. 2 , Grakhov V. P. 3 , Blum O. B. 4 1 Lichenology & Bryology, M. G. Kholodny Institute of Botany, Kyiv, Ukraine 2 Department of Botany, Taras Shevchenko National University of Kyiv, Kyiv, Ukraine 3 Center for Collective Use of Equipment Hplc, M. M. Gryshko National Botanical Garden, Kyiv, Ukraine 4 Chemotaxonomy and Bioindication, M. M. Gryshko National Botanical Garden, Kyiv, Ukraine Over 300 specimens of Cetraria aculeata group (C. aculeata, C. muricata, C. steppae) mainly from Ukraine and also from Poland, Hungary, Czech Republic, Russia, Azerbaijan, Kyrgyzstan and Turkey were studied for morphology, anatomy, chemistry, substrate specifity and geographic distribution. Previously known high level of phenotypic plasticity of these species (Kärnefelt, 1986) is confirmed upon the analyses of the specimens. Colored spot and microcrystal tests were used for norstictic acid detection in Cetraria specimens, but in this case they show inapplicability due to interfering components, while TLC and HPLC seem to be effective. HPLC demonstrates high variance of norstictic acid content in the studied thalli: from trace, minor, medium to major quantities which are not determined ecologically. The specimens collected from the same populations growing in the southern Russia and Ukraine regions and also Hungary may contain different amount of norstictic acid, even traces (detected by TLC as absence). Therefore distinguishing of C. steppae and C. aculeata species based on the presence/absence of norstictic acid (Kärnefelt, 1986) is considered as foundless. Taxonomic status of these southern populations (usually identified as C. steppae) should be investigated using specific molecular markers. Possible evolutionary and adaptive role of norstictic acid is of open question. Correct identification of C. steppae and C. aculeata species is also significant since C. steppae is included in the Red Data Book of Ukraine as vulnerable species. 106
The 7 th International Association for Lichenology Symposium 2012 (2A-2-P7) Submission ID: IAL0131-00002 TAXONOMIC REVISION OF THE USNIC ACID CONTAINING XANTHOPARMELIA SPECIES IN HUNGARY MORPHOLOGICAL, CHEMICAL AND MOLECULAR INVESTIGATIONS Farkas E. 1 , Lokos L. 2 , Molnar K. 1 1 Laboratory for Botany and Phytochemistry, Institute of Ecology and Botany of the Hungarian Academy of Sciences, Vacratot, Hungary 2 Department of Botany, Hungarian Natural History Museum, Budapest, Hungary Xanthoparmelia is one of the major genera of foliose lichens, and its research has long tradition in Hungary starting in 1925 with Vilmos Kőfaragó-Gyelnik’s taxonomic work on Parmelia. Following Klára Verseghy’s Hungarian lichen flora (1994) and Mason E. Hale’s world-monograph on Xanthoparmelia (1990), a modern taxonomic revision was carried out. This study consists of detailed morphological, chemical, and molecular analyses of all (appr. 500) herbarium specimens (including Gyelnik’s type materials) belonging to Parmelia s.l. species producing usnic acid, thus having yellowish-green upper surface (i.e., P. conspersa, P. hypoclysta, P. protomatrae, P. pulvinaris, P. subdiffluens, P. taractica, and P. tinctina), in the main Hungarian lichen herbaria (BP, EGR, JPU, SAMU, VBI). During this revision the occurrence of seven Xanthoparmelia species was confirmed by morphological and chemical analyses so far, namely: X. angustiphylla, X. conspersa, X. protomatrae, X. pulvinaris, X. stenophylla, X. subdiffluens, and X. tinctina. Four of them (X. angustiphylla, X. protomatrae, X. pulvinaris, and X. subdiffluens) were described from Hungary by Gyelnik in the 1900s, and the main populations of X. pulvinaris and X. subdiffluens are found in Hungary. The most important morphological characteristics, e.g., the types of lobes, isidia, rhizinae, pycnidia, and the color of the lower surface were considered during the revision. Since the secondary lichen compounds are taxonomically important in this group, HPTLC and LC MS were applied to determine these substances. The molecular phylogeny of these species is not explored yet, therefore the analysis of the sequences of three molecular markers (nuclear ITS and LSU rDNA, as well as mitochondrial SSU rDNA) are being processed. Maps of the Hungarian distribution for all species were prepared. Xanthoparmelia conspersa and X. stenophylla seem to be the most widely distributed and the most frequent species. X. protomatrae is located mostly in the Northern Hungarian Mountain Range, and seems to be missing from most of the Transdanubian habitats. X. subdiffluens occurs only in a very limited area in sandy habitats of the Danube- Tisza Interfluve. The current research has been supported by the Hungarian Scientific Research Fund (OTKA K81232). 107 2A-2-P
