taxonomic revision of the Lecania cyrtella group based on molecular and morphological evidence
Mycologia, 2008Co-Authors: Rikke Reese NæsborgAbstract:This investigation elucidates relationships within the Lecania cyrtella group (Ramalinaceae, lichenized Ascomycota) by employing morphological, anatomical and molecular methods. The morphological studies included eleven species of Lecania, L. cyrtella, L. cyrtellina, L. dubitans, L. erysibe, L. hutchinsiae, L. leprosa, L. madida, L. prasinoides, L. sambucina, L. sordida and L. sylvestris, and a key to the species plus species descriptions are provided. Lecania madida, a new species from the Pacific Northwest of North America, L. leprosa, a new species from eastern Europe, and L. sordida, a new species from Europe, are described here. The known range of L. prasinoides is greatly extended to include the Baltic countries, Nordic countries and western Canada. Lectotypes are designated for L. cyrtella and L. sambucina. Molecular relationships within the group were examined with haplotype network estimations and phylogenetic reconstructions. Part of the IGS region as well as the complete ITS region were sequenced and analyzed. Both the haplotype network and the phylogenetic analyses indicate that the included species, as conceived in the morphological examinations, all are monophyletic.

taxonomic revision of the Lecania cyrtella group ramalinaceae lichenized ascomycota based on molecular and morphological evidence
Mycologia, 2008Co-Authors: Rikke Reese NæsborgAbstract:This thesis focuses on phylogenetic, taxonomic, ecological, and conservation aspects of the crustose lichen genus Lecania (Ramalinaceae, lichenized Ascomycota). Lecania has previously been defined on basis of relatively few morphological characters, and the genus had never been treated in molecular phylogenies. The molecular phylogeny of the genus is inferred from DNA sequences. Twenty-five species traditionally placed in Lecania are included in the study along with 21 species from closely related genera. Lecania is a polyphyletic genus. A well-supported monophyletic group containing 16 Lecania species, including the type species L. fuscella is discovered, i.e. Lecania s. str. Nine species formerly included in Lecania do not belong in the genus. A new species, L. belgica, is described. The relationships of a group of morphologically similar Lecania species, i.e. the L. cyrtella group are investigated using morphological and molecular methods. Haplotype network and phylogenetic analyses indicate that the included species, as conceived in the morphological examinations, all are monophyletic. Two new species, L. leprosa and L. madida, are described, L. proteiformis is resurrected from synonymy, and the known range of L. prasinoides is greatly expanded. The type species Lecania fuscella has become endangered in many countries. Twelve localities in Sweden where the species had been found historically are investigated, but L. fuscella is only recovered in one locality. The species composition in these 12 localities, 58 old and 5 new collections with L. fuscella is determined and analyzed. The vegetation community differs between the old and the new collections, and between the locality where the species is recovered and those where it is not. Lecania fuscella has not been able to adapt to environmental changes and now only appears in a specific type of vegetation community. The phylogenetic diversity of the species is calculated, but does not reflect the species’ evolutionary potential.

Acta Botanica Hungarica, 2016Co-Authors: M. Haji Moniri, Sergey Y. Kondratyuk, P.p.g. Van Den BoomAbstract:A new for science species Lecania makarevicziae differing from L. pallida in having knobby to squamulose, blastidiate thallus, in having larger apothecia, in having a dark violet-brown disc, in having a plane disc, in having (1–2–)3-septate ascospores with slightly distinct constrictions at the septum, as well as in the lack of dense bluish pruina on apothecium disc, from Iran and Turkmenistan, is described, compared with closely related taxa.

Zarei-darki, Jae-seoun HurAbstract:The new genus Oxnerella is proposed for the lichen similar to Iranian endemic species Lecania ochronigra J. Steiner. Its isolated position in the phylogenetic tree after combined ITS nrDNA and 12S SSU mtDNA data set including members of the Ramalinaceae, Lecideaceae, Lecanoraceae and Megasporaceae is discussed. Description of the new species Oxnerella safavidiorum, comparison with allied taxa and illustrations is provided. The new combination ThamnoLecania racovitzae (basionym: Lecanora racovitzae Vain.) is proposed.

New and rare lichens for Russia and the Caucasus from high mountainous Dagestan (East Caucasus)
Acta Botanica Hungarica, 2019Co-Authors: Aziz Ismailov, G. P. UrbanavichusAbstract:Five species of lichenized ascomycetes are reported from high mountainous Dagestan. Acarospora laqueata, Lecania ochronigra and Protoparmelia placentiformis are new to Russia and the Caucasus (the last two). Anamylopsora pulcherrima is the first record of the genus and species for the North Caucasus. Buellia centralis is the first record for the Caucasus and second for Russia. Our records considerably extended information about geography and ecology of presented species especially the very rare species Buellia centralis, Lecania ochronigra and Protoparmelia placentiformis. The characteristic features of specimens with information of their morphology, anatomy, ecology and world distribution are given.
