  • Professor Ingvar Kärnfelt - a birthday tribute
  • 2009
  • Ingår i: The Lichenologist. - Cambridge : Cambridge University Press. - 0024-2829 .- 1096-1135. ; 41:5, s. 453-456

    • On 19 July 2009 Ingvar Kärnefelt celebrated his 65th birthday. This could have meant that we, his former students, would be celebrating him in his retirement from his position as head of the Biological Museums at Lund University. We are grateful that this is not the case, as Ingvar will carry on, probably for at least one or two more years. Instead, we celebrate Ingvar because he is the main reason for all of us having studied lichenology in Lund. This special issue of The Lichenologist is dedicated to him as a birthday tribute in honour of his long and fruitful lichenological career. The main authors of all the papers in this issue are former students of Ingvar. For several of us he has not only acted as supervisor but later also as the director of the Botanical Museum where we meet him in our daily work.

  • Considerations and consequences of allowing DNA sequence data as types of fungal taxa
  • 2018
  • Ingår i: IMA Fungus. - : INT MYCOLOGICAL ASSOC. - 2210-6340 .- 2210-6359. ; 9:1, s. 167-185
  • Tidskriftsartikel (refereegranskat)abstract
    • Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

  • Marchantiana asserigena comb. nov., a possible European immigrant from Australia
  • 2018
  • Ingår i: Graphis Scripta. - 0901-7593. ; 30:6, s. 115-120
  • Tidskriftsartikel (refereegranskat)abstract
    • Caloplaca asserigena is known to have a secondary compound different from other species of Teloschistaceae in the Northern Hemisphere. Studies of the secondary chemistry of the Australian Teloschistaceae have revealed the same compound to be present in Marchantiana michelagoensis and Caloplaca marchantiorum. Subsequent molecular studies based on three genes support the affinity of C. asserigena and M. michelagoensis. Accordingly, the species is tentatively included in the genus Marchantiana. Marchantiana asserigena, which was earlier regarded as extinct in Denmark, has been found to be widespread on very thin twigs of dwarf shrubs in Danish heathlands.

  • One hundred new species of lichenized fungi: a signature of undiscovered global diversity
  • 2011
  • Ingår i: Phytotaxa. - 1179-3163. ; 18, s. 1-127
  • Tidskriftsartikel (refereegranskat)abstract
    • The number of undescribed species of lichenized fungi has been estimated at roughly 10,000. Describing and cataloging these would take the existing number of taxonomists several decades; however, the support for taxonomy is in decline worldwide. In this paper we emphasize the dire need for taxonomic expertise in lichenology. We bring together 103 colleagues from institutions worldwide to describe a total of 100 new species of lichenized fungi, representing a wide taxonomic and geographic range. The newly described species are: Acarospora flavisparsa, A. janae, Aderkomyces thailandicus, Amandinea maritima, Ampliotrema cocosense, Anomomorpha lecanorina, A. tuberculata, Aspicilia mansourii, Bacidina sorediata, Badimia multiseptata, B. vezdana, Biatora epirotica, Buellia sulphurica, Bunodophoron pinnatum, Byssoloma spinulosum, Calopadia cinereopruinosa, C. editae, Caloplaca brownlieae, C. decipioides, C. digitaurea, C. magnussoniana, C. mereschkowskiana, C. yorkensis, Calvitimela uniseptata, Chapsa microspora, C. psoromica, C. rubropulveracea, C. thallotrema, Chiodecton pustuliferum, Cladonia mongkolsukii, Clypeopyrenis porinoides, Coccocarpia delicatula, Coenogonium flammeum, Cresponea ancistrosporelloides, Crocynia microphyllina, Dictyonema hernandezii, D. hirsutum, Diorygma microsporum, D. sticticum, Echinoplaca pernambucensis, E. schizidiifera, Eremithallus marusae, Everniastrum constictovexans, Fellhanera borbonica, Fibrillithecis sprucei, Fissurina astroisidiata, F. nigrolabiata, F. subcomparimuralis, Graphis caribica, G. cerradensis, G. itatiaiensis, G. marusa, Gyalideopsis chicaque, Gyrotrema papillatum, Harpidium gavilaniae, Hypogymnia amplexa, Hypotrachyna guatemalensis, H. indica, H. lueckingii, H. paracitrella, H. paraphyscioides, H. parasinuosa, Icmadophila eucalypti, Krogia microphylla, Lecanora mugambii, L. printzenii, L. xanthoplumosella, Lecidea lygommella, Lecidella greenii, Lempholemma corticola, Lepraria sekikaica, Lobariella sipmanii, Megalospora austropacifica, M. galapagoensis, Menegazzia endocrocea, Myriotrema endoflavescens, Ocellularia albobullata, O. vizcayensis, Ochrolechia insularis, Opegrapha viridipruinosa, Pannaria phyllidiata, Parmelia asiatica, Pertusaria conspersa, Phlyctis psoromica, Placopsis imshaugii, Platismatia wheeleri, Porina huainamdungensis, Ramalina hyrcana, R. stoffersii, Relicina colombiana, Rhizocarpon diploschistidina, Sticta venosa, Sagenidiopsis isidiata, Tapellaria albomarginata, Thelotrema fijiense, Tricharia nigriuncinata, Usnea galapagona, U. pallidocarpa, Verrucaria rhizicola, and Xanthomendoza rosmarieae. In addition, three new combinations are proposed: Fibrillithecis dehiscens, Lobariella botryoides, and Lobariella pallida.

  • Brigantiaea crystallina (Ascomycota, Teloschistales), a new species from South Korea and Japan.
  • 2018
  • Ingår i: Herzogia. - : Herzogia. - 0018-0971. ; 31:1, s. 424-429
  • Tidskriftsartikel (refereegranskat)abstract
    • Brigantiaea crystallina Arup is described as new to science from South Korea and Japan. It is similar to B. purpurata but has a pale to pale brownish orange hypothecium, an excipulum penetrated by brownish orange anthraquinonecrystals as well as colourless crystals that appear white in polarised light, the spores are smaller and the thallus lacks zeorine. The new species is illustrated and compared with similar species. A key to all Brigantiaea species of the world is also presented.

  • Four new species of Parvoplaca (Teloschistales, Ascomycota)
  • 2023
  • Ingår i: Plant and Fungal Systematics. - 2544-7459. ; 68:2, s. 294-303
  • Tidskriftsartikel (refereegranskat)abstract
    • The genus Parvoplaca is extended with four new species: P. candanii from Antarctica, P. lamprocarpa from Alaska, and P. macroborealis and P. tenebrosa from Oregon. Collections identified as P. tiroliensis are shown to form two independent clades when DNA was analyzed, but it is currently not clear which clade represents the species in a strict sense. Parvoplaca athallina has been considered an Antarctic species, but according to our analyses, the species is shown to be bipolar occurring also in northern Europe, Greenland, Alaska and in California.

  • The sister group relation of Parmeliaceae (Lecanorales, Ascomycota)
  • 2007
  • Ingår i: Mycologia. - : Informa UK Limited. - 0027-5514 .- 1557-2536. ; 99:1, s. 42-49
  • Tidskriftsartikel (refereegranskat)abstract
    • The family Parmeliaceae (Lecanorales, Ascomycota) is possibly the largest, best known and most thoroughly studied lichen family within its order. Despite this fact the relationship between Parmeliaceae and other groups in Lecanorales is still poorly known. The aim of the present study is to contribute to finding the sister group of Parmeliaceae as an aid in future studies on the phylogeny and character evolution of the group. We do this by sampling all potential relatives to the Parmeliaceae that we have identified, i.e. Cypsoplaca, Japewia, Mycoblastus, Protoparmelia, and Tephromela, a good representation of the major groups within the Parmeliaceae s. lat. and a good representation of other taxa in the core Lecanorales. We use molecular data from two genes, the large subunit of the nuclear ribosomal RNA gene (nrLSU) and the small subunit of the mitochondrial ribosomal RNA gene (mrSSU), and a Bayesian analysis of the combined data. The results show that the closest relatives to Parmeliaceae are the two genera Protoparmelia and Gypsoplaca, which are crustose lichens. Parmeliaceae in our sense is a well supported group, including also the family segregates Alectoriaceae, Hypogymniaceae, Usneaceae and Anziaceae.

  • Teloschistaceae (lichenized Ascomycota) from the Galapagos Islands : a phylogenetic revision based on morphological, anatomical, chemical, and molecular data
  • 2020
  • Ingår i: Plant and Fungal Systematics. - : W. Szafer Institute of Botany Polish Academy of Sciences. - 2544-7459. ; 65:2, s. 515-576
  • Tidskriftsartikel (refereegranskat)abstract
    • The lichen family Teloschistaceae from the Galapagos is revised. Most of the species belong to the Caloplacoideae, two to Teloschistoideae and a few to Xanthorioideae, three subfamilies not validly published, which is remedied here. Four different datasets were analyzed using Bayesian inference. For the bulk of the species, a combined dataset of nrITS, nrLSU and mrSSU was analyzed. Additionally, three analyses were performed using nrITS to further investigate phylogenetic relationships within and between species in each subfamily, and in the genera Xanthomendoza and Squamulea. Four new gen- era are described: Lacrima, Oceanoplaca, Phaeoplaca, Sucioplaca. Twenty-four species are reported, of which ten are new to science: Caloplaca nigra, Lacrima galapagoensis, Oceanoplaca chemoisidiosa, O. sideritoides, Phaeoplaca tortuca, Squamulea chelonia, S. humboldtiana, S. osseophila, S. oceanica, and Xanthomendoza leoncita. Several new combinations are proposed and three species of Xanthomendoza are reduced to synonymy. Several new combinations and species placed into synonymy do not occur in the Galapagos, but are treated as a consequence of our taxonomic revision. Morphology, anatomy, secondary chemistry, distribution and molecular phylogenetic affiliation are presented for each species and a key is provided. Eight different chemical patterns are quantitatively described based on HPLC analyses. The new genus Lacrima includes L. galapagoensis, a species without vegetative propagules, and two densely isidiate species, L. epiphora and L. aphanotripta that are morphologically similar to ‘Caloplaca’ wrightii. The only species of Galapagos Teloschistaceae that contains xanthones is placed into Huneckia. Oceanoplaca includes two species with the new anthraquinone isidiosin, O. isidiosa and O. chemoisidiosa, while a third species, O. sideritoides, does not contain this secondary metabolite. Phaeoplaca camptidia has previously been reported from Galapagos, but our phylogenetic analysis suggests that it is a new species, here named P. tortuca. An isolated position is occupied by ‘Caloplaca’ diplacia, which we place in it its own monotypic genus Sucioplaca. Some Galapagos Teloschistaceae can be considered a ‘residue’ of unresolved Caloplaca s.l., i.e. the corticolous C. floridana is possibly related to the saxicolous C. nigra, while C. cupuli­ fera can currently not be placed. Squamulea remains particularly problematic and includes S. phyllidizans, that is nested among otherwise unresolved Squamulea species. Based on molecular data, S. phyllidizans is close to ‘Huriella’. ‘Huriella’ flakusii, described from Peru, is confirmed to occur in the Galapagos and the genus is reduced to synonymy with Squamulea. The Squamulea squamosa/subsoluta group remains largely unresolved, but the new species S. chelonia, S. humboldtiana, S. oceanica, and S. osseophila are phylogeneti- cally distinct. Foliose Teloschistaceae are represented only by one species, described as Xanthomendoza leoncita, while the only fruticose species, Teloschistes chrysophthalmus and T. flavicans, are cosmopolitan."

  • Phylogenetic relationships within Pyrenodesmia sensu lato and the role of pigments in its taxonomic interpretation
  • 2021
  • Ingår i: Journal of Systematics and Evolution. - : Wiley. - 1674-4918 .- 1759-6831. ; 59:3, s. 454-474
  • Tidskriftsartikel (refereegranskat)abstract
    • Most lichens of the family Teloschistaceae (Ascomycota) produce yellow‐orange‐red anthraquinone pigments. However, the genus Pyrenodesmia encompasses species in which anthraquinones are absent and replaced by a gray pigment Sedifolia‐gray. It was shown recently that these species are related to taxa with both anthraquinones and Sedifolia‐gray (Caloplaca xerica group, C. haematites group, and C. cretensis) and to species with a brown pigment instead of both anthraquinones and Sedifolia‐gray (C. demissa, C. obscurella, and C. reptans). Nevertheless, relationships between mentioned anthraquinone‐containing and anthraquinone‐lacking species remained unclear. In total, 8 DNA loci from 41 species were used here to resolve these uncertainties. We concluded that C. demissa, C. obscurella, and C. reptans are rather distant from the core of Pyrenodesmia, and we place them outside of Pyrenodesmia sensu lato. Within Pyrenodesmia sensu lato, three lineages were revealed and recognized on a generic level: the genus Pyrenodesmia sensu stricto (21 species), the genus Kuettlingeria (14 species), which is resurrected here, and the genus Sanguineodiscus (4 species), which is newly described here. The genus Pyrenodesmia includes taxa that never contain anthraquinones, but Sedifolia‐gray. It matches with the former C. variabilis group. Taxa of the genera Kuettlingeria and Sanguineodiscus have anthraquinones in their apothecia and Sedifolia‐gray in their thalli. The genus Kuettlingeria includes the former C. xerica group plus C. cretensis and C. diphyodes. The genus Sanguineodiscus includes the former C. haematites group and C. bicolor. The identity of Kuettlingeria (Caloplaca) diphyodes was clarified and the name Pyrenodesmia helygeoides was resurrected. Twenty‐four new combinations were proposed.

  • Austroplaca sibirica (lichenized Ascomycota, Teloschistaceae) – a bipolar lichen with an austral origin documented by molecular data
  • 2021
  • Ingår i: Graphis Scripta. - 0901-7593. ; 33:1, s. 12-16
  • Tidskriftsartikel (refereegranskat)abstract
    • Based on molecular data, the austral lichen genus Austroplaca is shown to be represented in the Northern Hemisphere by the species Caloplaca sibirica. Accordingly, we make the combination Austroplaca sibirica. It grows on detritus and lignum in Canada, Greenland, Iceland, northern Scandinavia, Svalbard and Siberia and its southern range includes Patagonia (Argentina, Chile) and Kerguelen Islands. As its related species and genera are inhabitants of the Southern Hemisphere we hypothesize that it has migrated from the Southern to the Northern Hemisphere.
