Two new for science species of lichenicolous fungi, i.e. Lichenochora hypanica and Pyrenidium ucrainicum are described and illustrated, comparing with closely related taxa. The following taxa, i.e. Biatorella fossarum, Buelliella lecanorae, Echinothecium reticulatum, Lecanora pannonica, Melaspilea bagliettoana, and Opegrapha verrucariae are reported for the first time for Ukraine.
The electrochemical reduction of uranium oxide in the treatment of spent nuclear fuel requires a characterization of the LiCl-Li2O salt used as a reaction medium. Physical properties, melting and vaporization are important for the application of the salt
and thus they have been investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG), respectively. Experimental
data suggest LiCl and Li2O compound formations, leading to a melting point depression of the LiCl and a co-vaporization of the LiCl-Li2O salt.
Descriptions for 5 Caloplaca species new for science (C. chejuensis S. Y. Kondr. et J.-S. Hur, Caloplaca coreana S. Y. Kondr. et J.-S. Hur, C. galbina S. Y. Kondr. et J.-S. Hur (all from Korea), C. loekoesii S. Y. Kondr. et J.-S. Hur (from Korea and China), and C. safavidiorum S. Y. Kondr. et B. Zarei-Darki (from Iran)), as well as descriptions of 3 rediscovered species (Caloplaca diffluens (Hue) Zahlbr. (from Korea and China), C. multicolor (Hue) S. Y. Kondr. et J.-S. Hur, and C. spodoplaca (Nyl.) Zahlbr. (both from Korea), which were described from Korea and Japan more than one century ago and not recorded from that time), including diagnostic characters important for the present taxonomy of the genus Caloplaca s. l., are provided. The new combination, Caloplaca multicolor (Hue) S. Y. Kondr. et J.-S. Hur (Basionym: Lecidea multicolor Hue), is proposed.
From the combined phylogenetic analysis of multi-locus sequence data of the Lecanoraceae including two nuclear protein-coding markers (RPB2 and RPB1), the internal transcribed spacer and a fragment of the mitochondrial small subunit, found that the originally monotypic eastern Asian genus Verseghya is positioned within the Verseghya-Lecidella-Pyrrhospora clade of the Lecanoraceae and includes one more taxon Verseghya thysanophora widely distributed in Northern Hemisphere.
The genus Lecidella forming the Lecidella-Glaucomaria subclade within the same Verseghya-Lecidella-Pyrrhospora clade of the Lecanoraceae found to have tendency to be polyphyletic after including the recently described eastern Asian taxon Lecidella mandshurica into phylogenetic analysis of the Lecanoraceae. It is shown that Lecidella mandshurica was previously recorded from China sub Lecidella aff. elaeochroma.
The originally monotypic eastern Asian genus Sedelnikovaea forming a monophyletic branch within the Sedelnikovaea-Lecanoropsis subclade and being in out-position to the Rhizoplaca-Protoparmeliopsis s. str. clade of the Lecanoraceae found to include three more taxa, i.e. Sedelnikovaea marginalis, S. pseudogyrophorica, and S. subdiscrepans.
The Eurasian Protoparmeliopsis bolcana, and the eastern Asian P. kopachevskae, are illustrated for the first time as being positioned within the Protopameliopsis branch of the Lecanoraceae, while the South Korean ‘Protoparmeliopsis’ chejuensis found to be positioned in separate monophyletic branch from all other branches of the Rhizoplaca-Protoparmeliopsis s. l. clade of the Lecanoraceae.
The genus Polyozosia A. Massal. as earlier name for the former Myriolecis branch of the Lecanoraceae is accepted as far the type species of the latter genus, i.e. P. poliophaea, found to be positioned within this branch. The Polyozosia robust monophyletic branch is positioned in the outermost position in the Rhizoplaca-Protoparmeliopsis s. str. clade of the Lecanoraceae.
Position and species content of the accepted genera Glaucomaria, Lecanoropsis, Omphalodina, Polyozosia, and Straminella are discussed in separate nrITS and mtSSU, and combined phylogeny based on concatenated sequences of nrITS, mtSSU, RPB2 and RPB1 genes.
Fourty new combinations are proposed: Glaucomaria bicincta, G. carpinea, G. leptyrodes, G. lojkaeana, G. subcarpinea, G. sulphurea, G. swartzii, G. swartzii subsp. caulescens, G. swartzii subsp. nylanderi, Lecanoropsis anopta, L. macleanii, Omphalodina chrysoleuca, O. huashanensis, O. opiniconensis, O. phaedrophthalma, O. pseudistera, Palicella anakeestiicola, Polyozosia albescens, P. andrewii, P. contractula, P. crenulata, P. dispersa, P. hagenii, P. perpruinosa, P. populicola, P. pruinosa, P. reuteri, P. sambuci, P. semipallida, P. straminea, P. thuleana, Sedelnikovaea marginalis, S. pseudogyrophorica, S. subdiscrepans, Straminella bullata, S. burgaziae, S. conizaeoides, S. densa, S. maheui, S. varia, and Verseghya thysanophora. Validation of one name as Polyozosia perpruinosa Fröberg ex S. Y. Kondr. L. Lőkös et Farkas is also proposed.
Two new Xanthoria s. str. species, Xanthoria polessica and X. juniperina, the members of the Xanthoria parietina-group (from Belarus, Ukraine and Russia), and Rusavskia dasanensis (from Norway) are described, as well as compared with closely related taxa. Current position of 47 species of xanthorioid lichens described during the last two decades in 15 different genera of the subfamily Xanthorioideae of the family Teloschistaceae is discussed. Caloplaca herbidella (Arnold) H. Magn. and Telogalla olivieri (Vouaux) Nik. Hoff. et Hafellner are for the first time recorded for Belarus.
Brownlielloideae, a new subfamily in the Teloschistaceae, is proposed based on phylogenetic analyses of nuclear ribosomal DNA and 12S SSU mitochondrial DNA sequences. The data indicates that the new subfamily includes eight genera, i.e. Brownliella, Marchantiana and six new genera proposed here, Lazarenkoella, Raesaeneniana, Streimanniella, Tarasginia, Tayloriella and Thelliana. Lecanora kobeana Nyl. is lectotypified and shown to be an older name for the type species of the genus Brownliella, B. aequata. In addition, a seventh new genus, Neobrownliella is proposed in the subfamily Teloschistoideae. This new genus and the new species, Thelliana pseudokiamae are described. 13 new combinations are proposed: Brownliella kobeana, Fulgogasparrea appressa, Lazarenkoella zoroasteriorum, Neobrownliella brownlieae, N. montisfracti, Raesaeneniana maulensis, Streimanniella burneyensis, S. kalbiorum, S. michelagoensis, S. seppeltii, Tarasginia tomareeana, T. whinrayi and Tayloriella erythrosticta.
The new genus Kashiwadia S. Y. Kondr., L. Lőkös et J.-S. Hur, gen. nov. for the Eastern Asian species Physcia orientalis Kashiw. being in isolated position in the genus Physcia after morphological and anatomical characters as well as showing closer relation to the Heterodermia branch (than to the Physcia branch) in phylogenetic tree of the Physciaceae based on results of ITS1/ITS2 nuclear ribosomal and positioning in separate branch after 12S SSU mitochondrial DNA sequences and combined data set is proposed. Description of new genus and new combination is provided.
Physcia ucrainica sp. n. from the Crimean Peninsula, Ukraine, sharing diagnostic morphological characters of the Physcia adscendens and P. stellaris groups (Physciaceae, Ascomycota) and its transitional position between the mentioned groups in the phylogenetic tree of the Physciaceae based on combined ITS1/ITS2 nrDNA and 12S SSU mtDNA sequences is presented.
A few additional, rare for the “Novy Svit” Botanical Reserve area, the Crimean Peninsula, and Ukraine, taxa of lichen-forming and lichenicolous fungi are mentioned as well.
Four new monophyletic groups are found within the teloschistoid clade of the subfamily Xanthorioideae in the Teloschistaceae using nuclear (ITS1/ITS2) and mitochondrial (12S mtSSU gene) DNA sequences. These groups are proposed as new genera: Brownliella gen. nova for the widely distributed Caloplaca cinnabarina group, Filsoniana gen. nova for the Australian Caloplaca australiensis group, Fulgogasparrea gen. nova for the Western Pacific species Caloplaca decipioides, and Kaernefia gen. nova for the Southern Hemisphere Caloplaca kaernefeltii group. Massalongo’s genus Niorma is resurrected for the Teloschistes hypoglaucus group.
The phylogeny of the subfamily Xanthorioideae (Teloschistaceae) is re-analysed based on ITS, LSU and mtSSU sequences, including a new set of specimens representing 31 genera, of which five are proposed as new: Golubkovia, Igneoplaca, Langeottia, Scythioria and Verrucoplaca. Two new species, Ovealmbornia volkmarwirthii from South Africa and Gondwania sejongensis from Antarctica are described, illustrated and compared with closely related taxa. Eleven new combinations are proposed in the genera Calogaya, Cerothallia, Flavoplaca, Gondwania, Igneoplaca, Scythioria and Verrucoplaca, but the status of four earlier established genera, Pachypeltis, Parvoplaca, Solitaria and Xanthopeltis, remains uncertain and needs further studies.
