Abstract

Aptroot, A., Schumm, F. & Gabriel, R. 2009. Lichens new to the Azores collected on Terceira. - Herzogia 22: 147-152. Forty-six lichen species and one variety are reported for the first time from the Azores. All were collected during a one-week field course on Terceira and include the first record of Biatora britannica outside Britain, and a record of Xanthoria weberi bridging the gap between the disjunct areas it has been reported from, viz. America and northern Europe. Xanthoria weberi is a new combination. Zusammenfassung: Aptroot, A., Schumm, F. & Gabriel, R. 2009.

Alle wurden wäh- rend eines einwöchigen Geländekurses auf Terceira gesammelt und beinhalten den ersten Fund von Biatora bri- tannica außerhalb der Britischen Inseln.

Forty-six lichen species and one variety are reported for the first time from the Azores. All were collected during a
one-week field course on Terceira and include the first record of Biatora britannica outside Britain, and a record of
Xanthoria weberi bridging the gap between the disjunct areas it has been reported from, viz. America and northern
Europe. Xanthoria weberi is a new combination.

... By comparing our material of the new species with specimens of Lecanographa in BR herbarium, we found that specimen Aptroot 68236 classified as Lecanographa subgrumulosa was similar to L. atlantica. Lecanographa subgrumulosa has been reported twice as new to the Azores by Aptroot & Rodrigues (2005) and Aptroot et al. (2009), but the latter authors wrote that their "material differs from the description in Egea & Torrente (1994) by the presences of some ascospores with additional (up to 7) septa". Lecanographa subgrumulosa should thus be excluded from the Azores lichen checklist. ...
Lecanographa atlantica (Arthoniales, Lecanographaceae), a widespread and conspicuous but still undescribed lichen-forming fungus
Article
  • Nov 2020
Lecanographa farinosa was considered to be a lichen inhabiting coastal rocks of the Mediterranean region and to possess psoromic and conpsoromic acids as major secondary metabolites. A revision of its type specimen from Germany proved that the species has been misunderstood. In this paper, L. farinosa is shown to have a thallus containing confluentic and 2’-O-methylmicrophyllinic acids and to have a different ecology and distribution. A revision of previous reports of L. farinosa from continental Portugal and the study of recent specimens of Lecanographa cf. farinosa from the Azores, Canary Islands, Cape Verde and continental Portugal revealed a new species described as L. atlantica. Moreover, reports of L. dialeuca from France (Brittany) and of L. subgrumulosa from the Azores are considered misidentifications of L. atlantica. This latter has thus a widespread distribution ranging from the Azores to the Atlantic coast of the European continent where it inhabits volcanic rocks near the sea. Lecanographa atlantica is characterized by a whitish to cream coloured thallus, usually rounded or oblong to shortly lirelliform and white pruinose ascomata with a widely exposed hymenial disc and thin margin, (3–)5–7-septate ascospores of (16–)18.9–23(–26) × (3–)3.4–4(–4.5) µm, and a chemistry including at least 2’-O-methylperlatolic acid but lacking confluentic and 2’-O-methylmicrophyllinic acids. Psoromic acid is sometimes present in L. atlantica but its origin is unclear. Phylogenetic analyses using nuLSU sequences place L. atlantica as sister to L. hypothallina.
... Habitat and distribution in Europe. Zwackhia sorediifera was reported, e.g., from the Azores [404], Denmark [163], Estonia [123], France [405], Great Britain [92], Lithuania [173,174], and Norway and Sweden [97]. ...
The lichen genus Opegrapha s. l. in Poland: morphological variability, ecology, and distribution
Article
Full-text available
  • Dec 2018
This monograph presents the results of research on the morphological and anatomical variability, ecology, and distribution of Opegrapha s. l. in Poland. The study is based on roughly 1,400 specimens from Polish and some European herbaria. Out of the 18 species of the genus Opegrapha s. l. recorded from Poland, seven species belong to the genus Opegrapha Ach., four species now belong to the genus Alyxoria Ach. ex Gray, two species each are found in the genera Arthonia Ach. and Zwackhia Körb, and one species belongs to each of the genera Gyrographa Ertz & Tehler, Phacographa Hafellner, and Pseudoschismatomma Ertz & Tehler. One of the species, Zwackhia sorediifera , has been reported from Poland for the first time. Among the 18 species of the genus Opegrapha s. l., 10 are epiphytic, five epilithic, and two lichenicolous. The first modern identification key for the species of Opegrapha s. l. in Poland is presented. Numerous new regional records are provided that complement our knowledge of the geographic distribution of some poorly known taxa, such as Alyxoria culmigena , A. mougeotii , A. ochrocheila , Arthonia calcarea , Opegrapha dolomitica , O. geographicola , O. lithyrga , and Phacographa glaucomaria . All species are characterized and discussed, and their diagnostic characters illustrated. Geographic ranges of each species in Poland are presented on maps based on revised herbarium materials.
... Apothecia are absent in the Belarusian material. Sterile specimens are similar to Biatora britannica Printzen, Lumbsch & Orange (see Printzen et al. 2001), which is known only from Great Britain, the Azores and Madeira so far ( Aptroot et al. 2009, van den Boom 2015. However, according to Printzen & Coppins (2009) the latter is a western species, and has never been reported from continental Europe so far. ...
New or Otherwise Interesting Records of Lichens and Lichenicolous Fungi from Belarus. III. With an Updated Checklist of Lichenicolous Fungi
Article
  • Jul 2017
Data on 13 species of lichenized and lichenicolous fungi from Belarus are presented; two lichens (Biatora efflorescens and Catillaria croatica) and ten lichenicolous fungi (Abrothallus microspermus, A. suecicus, Arthonia phaeophysciae, Arthrorhaphis aeruginosa, Merismatium decolorans, Phacopsis oxyspora, Polycoccum peltigerae, Pronectria subimperspicua, Taeniolella delicata and Zwackhiomyces echinulatus) are new to the country. Diploschistes muscorum is reported on lichens for the first time from Belarus. An updated checklist of lichenicolous fungi known from Belarus is also provided.
First insights into genetic diversity and relationships of European taxa of Solenopsora (Catillariaceae, Ascomycota) with implications for their delimitation
Article
The lichen genus Solenopsora occurs predominantly in temperate and subtropical regions of the world, and the centre of diversity and distribution is in the Mediterranean, Macaronesian, and Madrean floristic regions. Taxonomic treatment of several taxa has varied over time and the concepts lack clarity. Focusing on multilocus sequence data, morphology, anatomy, chemistry, and ecological preferences, the present study investigates European Solenopsora taxa to obtain the first insights into their genetic variation and relationships. Our results show discrepancy between the number of currently recognized taxa in Europe and the number of genetic entities identified. We recognize eight species in the genus in Europe: Solenopsora candicans, Solenopsora cesatii (including Solenopsora carpatica), Solenopsora grisea, Solenopsora holophaea, Solenopsora liparina, Solenopsora marina, Solenopsora olivacea, and Solenopsora vulturiensis. We gathered evidence to recognize S. liparina, an edaphic vicariant of S. candicans confined to ultramafic rocks, as a separate species. We disclosed a previously unknown sister relationship between S. grisea and S. vulturiensis. Taxonomic synopses, geographical distribution, and an identification key for the treated taxa are provided. Phylogenetic analyses revealed two major lineages among the European Solenopsora spp., differentiated by thallus organization, the presence/absence of rhizines on lower side of the thallus, secondary chemistry, and anatomy of upper cortex. The generic circumscription and phylogenetic position, however, appear problematic and additional studies with increased sampling including related genera are needed. © 2014 The Linnean Society of London, Botanical Journal of the Linnean Society, 2014, ●●, ●●–●●.
Diplotomma, Lecanora, and Xanthoria lichen species new to Turkey
Article
Full-text available
During a recent excursion in Kemaliye district of Erzincan region (Turkey), we sampled lichens from 6 localities, among which Diplotomma hedinii, Lecanora valesiaca, and Xanthoria weberi were determined as new to Turkey and the Middle East and X. weberi also new to Asia. Geographic distribution, substrate, chemistry, and comparisons with morphologically similar taxa are presented.
