These compounds are frequently deposited as crystals outside the fungal hyphae and most of them emit visible fluorescence when excited by UV. We wondered whether the conversion of UV into visible fluorescence might be photosynthetically used by the photobiont, thereby converting UV into useful energy. To address this question, thalli of Xanthoria parietina were used as a model system. In this species the anthraquinone parietin accumulates in the outer upper cortex, conferring the species its characteristic yellow-orange colouration. In ethanol, parietin absorbed strongly in the blue and UV-B and emitted fluorescence in the range 480–540 nm, which partially matches with the absorption spectra of photosynthetic pigments. In intact thalli, it was determined by confocal microscopy that fluorescence emission spectra shifted 90 nm towards longer wavelengths. -

Molecular Phylogenetic Study at the Generic Boundary Between the Lichen-Forming Fungi Caloplaca and Xanthoria (Ascomycota, Teloschistaceae)
Mycol. Res. 107 (11): 1266–1276 (November 2003). f The British Mycological Society 1266 DOI: 10.1017/S0953756203008529 Printed in the United Kingdom. Molecular phylogenetic study at the generic boundary between the lichen-forming fungi Caloplaca and Xanthoria (Ascomycota, Teloschistaceae) Ulrik SØCHTING1 and Franc¸ ois LUTZONI2 1 Department of Mycology, Botanical Institute, University of Copenhagen, O. Farimagsgade 2D, DK-1353 Copenhagen K, Denmark. 2 Department of Biology, Duke University, Durham, NC 27708-0338, USA. E-mail : [email protected] Received 5 December 2001; accepted 5 August 2003. A molecular phylogenetic analysis of rDNA was performed for seven Caloplaca, seven Xanthoria, one Fulgensia and five outgroup species. Phylogenetic hypotheses are constructed based on nuclear small and large subunit rDNA, separately and in combination. Three strongly supported major monophyletic groups were revealed within the Teloschistaceae. One group represents the Xanthoria fallax-group. The second group includes three subgroups: (1) X. parietina and X. elegans; (2) basal placodioid Caloplaca species followed by speciations leading to X. polycarpa and X. candelaria; and (3) a mixture of placodioid and endolithic Caloplaca species. The third main monophyletic group represents a heterogeneous assemblage of Caloplaca and Fulgensia species with a drastically different metabolite content. We report here that the two genera Caloplaca and Xanthoria, as well as the subgenus Gasparrinia, are all polyphyletic. The taxonomic significance of thallus morphology in Teloschistaceae and the current delimitation of the genus Xanthoria is discussed in light of these results. INTRODUCTION Taxonomy of Teloschistaceae and its genera The Teloschistaceae is a well-delimited family of Hawksworth & Eriksson (1986) assigned the Teloschis- lichenized fungi. -

INTRODUCTION Lichens are a product of symbiotic association of two unrelated organisms, a primary producer (photobiont) - cyanobacteria or algae - and a primary consumer, a type of fungi (mycobiont), forming a new biological entity, with no resemblance to its individual components, due to non-structural, biochemical changes and physiological essentials for morphological differentiation, interaction and stability of the association. -

Blas- tenia scabrosa is a new combination supported by molecular data. Blastenia scabrosa, Caloplaca fuscorufa and Flavoplaca havaasii are new to Russia. Blastenia scabrosa is also new to the Caucasus Mts and Sweden. Detailed morphological measurements of the Russian specimens of these species are provided. Caloplaca exsecuta, C. grimmiae and C. sorocarpa are new to the Murmansk region. The taxonomic position of C. alcarum is briefly discussed. Key words: Arctic, Rybachy Peninsula, Caloplaca s. lat., Blastenia scabrosa. Introduction Although the Murmansk region is one of the best studied regions of Russia in terms of lichen diversity, there are numerous reports in recent literature of new discoveries there (e.g. Fadeeva et al. 2013; Konoreva 2015; Melechin 2015; Urbanavichus 2015). Several localities in the northwest of the Murmansk region, mainly on the Pechenga Tundra Mountains and the Rybachy Peninsula, were visited in 2013 and 2015. -

China * Correspondence to: [email protected] Abstract—Huneckia pollinii and Flavoplaca oasis are described and illustrated from Chinese specimens. The two species and the genus Huneckia are recorded for the first time from China. Keywords—Asia, lichens, taxonomy, Teloschistaceae Introduction Teloschistaceae Zahlbr. is one of the larger families of lichenized fungi. It includes three subfamilies, Caloplacoideae, Teloschistoideae, and Xanthorioideae (Gaya et al. 2012; Arup et al. 2013). Many new genera have been proposed based on molecular phylogenetic investigations (Arup et al. 2013; Fedorenko et al. 2012; Gaya et al. 2012; Kondratyuk et al. 2013, 2014a,b, 2015a,b,c,d). Currently, the family contains approximately 79 genera (Kärnefelt 1989; Arup et al. 2013; Kondratyuk et al. 2013, 2014a,b, 2015a,b,c,d; Søchting et al. 2014a,b). Huneckia S.Y. Kondr. et al. was described in 2014 (Kondratyuk et al. 2014a) based on morphological, anatomical, chemical, and molecular data. It is characterized by continuous to areolate thalli, paraplectenchymatous cortical # Cong-Cong Miao & Xiang-Xiang Zhao contributed equally to this research. -
