- 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.

- New records, range extensions and nomenclatural innovations for lichens and lichenicolous fungi from Alaska, U.S.A. - Herzogia 25: 177-210. Surveys of lichens and lichenicolous fungi have been taking place in the U.S. state of Alaska for more than 160 years, but until now assessing the full extent of their diversity has been hampered by the lack of a comprehensive and synonymized baseline inventory. In this paper we will begin to redress this by resolving outstanding nomenclatural issues and providing voucher data for a forthcoming catalog of Alaskan lichens, specifically: 1) synonymization,and/or resolution of status of species previously reported from Alaska, with emphasis on Alaskan types; 2) species new to the Alaska lichen biota; and 3) biogeographically significant new records from within Alaska. We report 91 species new to the flora of Alaska, including 65 lichens, three saprophytic calicioid fungi and 23 lichenicolous fungi. Of these, we report thirteen species, Biatora sphaeroidiza, Biatorella conspurcans, Chaenothecopsis arthoniae, Collemopsidium foveolatum, Dactylospora frigida, Halospora discrepans, Lecanora bryopsora, Opegrapha geographicola, Peltigera lyngei, Petractis clausa, Protoblastenia cyclospora, Thelocarpon impressellum and Usnea cylindrica as new to North America. In addition, Arthonia pruinata and Flavocetraria minuscula are new to Canada and Adelococcus alpestris new to the United States. We further place the following five names into synonymy: Lecania disceptans (Nyl.) Lynge [= Halecania alpivaga (Th.Fr.) M.Mayrhofer], Lecidea pallidella Nyl. [= Lecania subfuscula (Nyl.) S.Ekman], Lempholemma triptodes (Nyl.) Zahlbr. Leciophysma finmarkicum Th.Fr.), Polyblastia obtenta (Nyl.) Lynge [= Sporodictyon terrestre (Th.Fr.) S.Savic & Tibell], and Verrucaria pernigrata Nyl. [= Protothelenella sphinctrinoides (Nyl.) H.Mayrhofer & Poelt]. We propose restoring the long overlooked taxon Polyblastia exalbida (Nyl.) Zahlbr., currently known only from Alaska, to the North American lichen checklist. Finally, we propose the new combination Puttea caesia (Fr.) M.Svensson & T.Sprib. to replace Lecidea symmictella Nyl., which becomes a synonym.

A new lichenicolous species of Carbonea (Ascomycota, Lecanoraceae) from northern Sweden
- 2021
-
Ingår i: Phytotaxa. - : Magnolia Press. - 1179-3155 .- 1179-3163. ; 522:3, s. 221-230

Tidskriftsartikel (refereegranskat)abstract
- Carbonea is a widely distributed genus of lecideoid fungi, including both lichenized and non-lichenized, often parasitic species. We describe the new, non-lichenized species Carbonea tephromelae, based on material collected in the Swedish part of the Scandes. The new species is characterized by a colourless hypothecium, broadly ellipsoid to globose ascospores, and by growing on the thallus of the common saxicolous lichen Tephromela atra. It is similar to the likewise lichenicolous species C. supersparsa and C. vitellinaria, but is clearly separated from these species by anatomy and in a phylogenetic analysis based on four markers (mrSSU, ITS, RPB1, RPB2). Carbonea tephromelae is apparently specific to T. atra, but the use of host specificity as a character for species delimitation in lichenicolous species of Carbonea needs further evaluation.

- Förra året beslutade SLF att 'adoptera' Skäckerfjällen i Jämtland, vilket innebär att föreningen avser att göra en fullständig inventering av dess lavar genom återkommande besök under ett antal år. Första besöket gjordes under höstexkursionen 2008 i mångahanda spännande miljöer, såsom kalkbranter, bäckraviner med gammal granskog, videsnår, snölegor och fjälltoppar med urberg. Exkursionen resulterade i en imponerande artlista med bl.a. två nya arter för Sverige.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- SLF:s exkursion till Skäckerfjällen 2008 var en strålande succé (se Lavbulletinen 2009-1), vilket säkert bidrog till att många anmälde intresse när det annonserades att det var dags för ett återbesök i detta nederbördsrika och geologiskt omväxlande jämtländska naturreservat. Allteftersom veckorna gick duggade desvärre återbuden lika tätt som regndropparna i den dystra väderleksprognosen för den aktuella helgen, men till sist var det ändå sex tappra som drog på sig sina ryggsäckar och började vandra mot Rutsdalen.

-
Tidskriftsartikel (refereegranskat)abstract
- We present taxonomic, distributional and ecological notes on Fennoscandian crustose lichens and lichenicolous fungi, based on new collections as well as revision of herbarium material. Two new combinations are proposed: Frutidella furfuracea comb. nov. for F. pullata and Puttea duplex comb. nov. for Fellhanera duplex. Lecidea byssoboliza, L. carneoglauca and Variolaria torta are all reduced to synonymy with Bacidia antricola, Bacidia invertens is synonymized with B. igniarii, B. atrolivida with Mycobilimbia tetramera, and Gyalidea fruticola with Thelenella pertusariella. A new description is provided for Micarea hylocomii. 25 species of lichens and lichenicolous fungi are reported as new to Finland, Norway and/or Sweden: Absconditella lignicola (Norway), Bacidia antricola (Norway), B. polychroa (Norway), B. pycnidata (Sweden), Bacidina adastra (Sweden), Biatora veteranorum (Norway), Briancoppinsia cytospora (Finland), Catillaria scotinodes (Norway), Cliostomum subtenerum (Norway), Dirina fallax (Sweden), Fellhaneropsis almquistiorum (Norway), Gyalidea subscutellaris (Sweden), Lecania inundata (Norway), L. suavis (Norway), Micarea capitata (Norway), M. deminuta (Norway), M. hylocomii (Sweden), M. lynceola (Sweden), M. soralifera (Sweden), M. subconfusa (Sweden), Mycoblastus sanguinarioides (Finland, Sweden), Paralecia pratorum (Sweden), Puttea duplex (Sweden), Sarcogyne algoviae (Finland) and Toninia subnitida (Norway). Lectotypes are designated for Bacidia antricola, Lecidea byssoboliza, Lecidea carneoglauca, Lecidea subconfusa and Lecidea submoestula.

The circumscription and phylogenetic position of Bryonora (Lecanoraceae, Ascomycota), with two additions to the genus
- 2022

Ingår i: Mycologia. - : Taylor & Francis. - 0027-5514 .- 1557-2536. ; 114:3, s. 516-532

Tidskriftsartikel (refereegranskat)abstract
- Lecanoraceae is one of the largest families of the Lecanoromycetes, with about 30 accepted genera, many of which, however, have uncertain status and/or circumscriptions. We assess the phylogenetic position of the genus Bryonora and its segregate Bryodina for the first time, using a six-locus phylogeny comprising the Lecanoraceae as well as closely related families. We find strong support for the placement of Bryonora in the Lecanoraceae, whereas there is no support for treating Bryodina as a genus separate from Bryonora. Hence, we reduce Bryodina to synonymy with Bryonora. Further, we describe Bryonora microlepis as new to science and transfer Lecanora castaneoides to Bryonora and L. vicaria to Miriquidica. A world key to Bryonora is included.
