Stone D.F. & McCune B. (2022): Two new hairy Leptogium (Collemataceae) species from western North America, Bryologist, 125(1): 157–169

Leptogium bacatum is described as a new species with spherical-celled (moniliform) hairs and Leptogium umpquaense has matted, tangled hairs on the upper surface. Both are in the so-called section Mallotium. The species differ in morphology and DNA sequences from others in this group. We supplement existing GenBank data with new ITS and nuLSU sequences for 12 Leptogium specimens from Arizona, California, Mexico, New Mexico, Oregon, Nova Scotia and Ontario. Leptogium bacatum is distinguished by … Read more...

McCune B., Schultz M., Fennell T., Passo A. & Rodriguez J.M. (2022): A new endemic, Pannaria oregonensis, replaces two misapplied names in the Pacific Northwest of North America, Bryologist, 125(1): 170–185

We evaluated the taxonomic status of specimens representing two listed rare species of Pannaria in the Pacific Northwest, P. rubiginosa and P. rubiginella, based on DNA sequences of recently collected samples. We combined those data with new sequences for other Pannaria species in North America and South America as well as all available sequences from the P. rubiginosa and P. lurida groups plus closely related P. hookeri, based on results from initial analyses. Historically, P. rubiginosa and … Read more...

Kondratyuk S.Y. & Mosyakin S.L. (2022): Wilketalia S.Y.Kondr., a new name for Andina Wilk, Pabijan & Lücking, nom. illeg. (Teloschistaceae, lichenized Ascomycota), Ukrainian Botanical Journal, 79(1): 3–5

A new generic name, Wilketalia S.Y.Kondr. (nom. nov.; Teloschistaceae, lichenized Ascomycota), is published to replace the name Andina Wilk, Pabijan & Lücking (nom. illeg.), which is an illegitimate later homonym of Andina J.A.Jiménez & M.J.Cano (Pottiaceae, Bryophyta) and Andinia (Luer) Luer (Orchidaceae). A new species-rank combination Wilketalia citrinoides (Wilk & Lücking) S.Y.Kondr. (Andina citrinoides Wilk & Lücking) is also validated. Brief nomenclatural comments are provided. Keywords: … Read more...

Yamano Y. & Rakotondraibe H.L. (2022): Understanding the biosynthesis of paxisterol in lichen-derived Penicillium aurantiacobrunneum for production of fluorinated derivatives, Molecules, 27(5): 1641 [7 p.]

The U.S. endemic lichen (Niebla homalea)-derived Penicillium aurantiacobrunneum produced a cytotoxic paxisterol derivative named auransterol (2) and epi-citreoviridin (6). Feeding assay using 13C1-labelled sodium acetate not only produced C-13-labelled paxisterol but also confirmed the biosynthetic origin of the compound. The fluorination of bioactive compounds is known to improve pharmacological and pharmacokinetic effects. Our attempt to incorporate the fluorine atom in paxisterol and its derivatives … Read more...

Chen P., Liu L., Xie C. & Zhang L. (2022): Four new species of Herpothallon (Arthoniaceae, Arthoniales, Arthoniomycetes, Ascomycota) from China, Phytotaxa, 536(1): 83–91

Four new species of Herpothallon: H. capilliferum, H. polyisidiatum, H. subglobosum and H. viridi-isidiatum are described from southern China. Detailed taxonomic descriptions, ecological and chemical characters, and illustrations are provided for the new species. A key to all known Chinese Herpothallon species is also provided. Keywords: Arthoniaceae, East Asia, lichenized fungi, taxonomy, lichens. Read more...

Ohmura Y., Sugimoto M., Yakovchenko L. & Davydov E.A. (2022): Additional species and ITS rDNA data for the lichen mycota of the Imperial Palace Grounds, Tokyo, Japan, Bulletin of the National Museum of Nature and Science. Series B, Botany [Tokyo], 48(1): 1–6

The lichen mycota of the Imperial Palace Grounds, Tokyo, Japan was revised in the light of ITS rDNA sequences and updated knowledge. The following, formerly unidentified or misidentified species were revealed: Candelaria asiatica (as ‘C. concolor’) and Flavoplaca flavocitrina (as ‘Caloplaca aff. citrina’) are new to Japan, and Cladonia rei (as ‘C. ramulosa’), Pertusaria flavicans, Phaeographis pruinosa, and Phaeophyscia limbata (as ‘P. hispidula’) are new to the Imperial Palace Grounds. … Read more...

Adrees M., Habib K. & Khalid A.N. (2022): Bacidia suffusa (Fr.) A. Schneider (Ramalinaceae), an addition to the lichen biota of Pakistan confirmed by molecular phylogeny, Pakistan Journal of Botany, 54(2): 731–736

Bacidia suffusa, a member of lichenized family Ramalinaceae is reported on the bark of Alnus nitida, from Himalayan moist temperate forest of Pakistan, based on critical morpho-anatomical and ITS-based phylogenetic analysis. Its occurrence here indicates that it is the first report of this lichen from Pakistan and South East Asia as well. The taxonomic characters of the taxon are given, along with an ITS-based phylogenetic tree and notes on its ecology and distribution. Key words: Himalaya, … Read more...

Holien H. & Frisch A. (2022): Perigrapha superveniens (Nyl.) Hafellner, a lichenicolous fungus new to Fennoscandia from Norway, Graphis Scripta, 34(3): 36–41

The lichenicolous fungus Perigrapha superveniens (Nyl.) Hafellner is reported from Norway for the first time from three separate localities. It is a gall inducing obligate parasitic fungus on Parmelia sulcata and seems to prefer highly oceanic areas. A brief description of the species and notes on its ecology and distribution are provided. Read more...

Nelsen M.P., Leavitt S.D., Heller K., Muggia L. & Lumbsch H.T. (2022): Contrasting patterns of climatic niche divergence in Trebouxia—A clade of lichen-forming algae, Frontiers in Microbiology, 13: 791546 [11 p.]

Lichen associations are overwhelmingly supported by carbon produced by photosynthetic algal symbionts. These algae have diversified to occupy nearly all climates and continents; however, we have a limited understanding of how their climatic niches have evolved through time. Here we extend previous work and ask whether phylogenetic signal in, and the evolution of, climatic niche, varies across climatic variables, phylogenetic scales, and among algal lineages in Trebouxia—the most common genus … Read more...
