Haldeman M. & McCune B. (2021): Tephromela eviolacea, a new species of Tephromela (Tephromelataceae) lacking a violet hymenium from northwestern North America, Bryologist, 124(2): 230–241

We describe Tephromela eviolacea as a new species from California, Idaho and Washington, U.S.A. Externally we cannot distinguish it from T. atra and T. pacifica, but it differs from both in ITS sequences, secondary metabolites and in lacking all violet coloration in the hymenium. In the Pacific Northwest, T. atra is found on rock and T. eviolacea and T. pacifica are found on bark and wood on the east and west sides of the Cascade Range, respectively. We provide a key to the genus in the region. Keywords: … Read more...

Davydov E.A., Yakovchenko L.S., Hollinger J., Bungartz F., Parrinello C. & Printzen C. (2021): The new genus Pulvinora (Lecanoraceae) for species of the ‘Lecanora pringlei’ group, including the new species Pulvinora stereothallina, Bryologist, 124(2): 242–256

Phylogenetic reconstructions based on ITS/5.8S, mtSSU and nuLSU DNA sequence data suggest that Lecanora pringlei from North America and a closely related new species from the Altai Mountains, Russia, should be transferred to a new genus Pulvinora, phylogenetically related to Frutidella. It is distinguished by Lecanora-type asci, mycolecanorine apothecia soon becoming convex with an algal layer pushed below the hypothecium, and a pulvinate thallus with squamules at the tip of pseudopodetialike, … Read more...

(2021): How to publish a new fungal species, or name, version 3.0, IMA Fungus, 12: 11 [15 p.]

It is now a decade since The International Commission on the Taxonomy of Fungi (ICTF) produced an overview of requirements and best practices for describing a new fungal species. In the meantime the International Code of Nomenclature for algae, fungi, and plants (ICNafp) has changed from its former name (the International Code of Botanical Nomenclature) and introduced new formal requirements for valid publication of species scientific names, including the separation of provisions specific to … Read more...

Haldeman M. (2021): New and interesting records of lichens, lichenicolous fungi and other Ascomycota from northwestern USA III, Evansia, 37(3): 71–80

The lichenicolous fungi Lichenochora aipoliae, Stigmidium leprariae and Taeniolella toruloides are reported as new to North America, and Monodictys epilepraria as new to western North America. A record of Lawalreea cf. lecanorae from the region is discussed. The lichen Biatora oligocarpa is reported as new to the contiguous 48 states of the USA. Also reported new to northwestern North America are two Ascomycota microfungi, Gloniopsis subrugosa and Nemania maritima. In total, new state records … Read more...

Arup U., Blom H.H. & Lindblom L. (2021): The Gaupne area in Sogn og Fjordane – a hot-spot for lichens in Norway, Graphis Scripta, 33(3): 31–49

During a three-day field trip to the Gaupne area, Luster kommune, three main localities were visited in search of lichens. A total of 35 lichens or lichenicolous fungi were found to be new to Sogn og Fjordane, most of which are also rare on a national scale. Three species on rocks, Calogaya biatorina, Lecanora gislerianaand L. subaurea, are red-listed and two species, Blastenia monticolaand Caloplaca squamuleoisidiata, are new to Norway. Most of the species new to Sogn og Fjordane … Read more...

Timdal E. & Tønsberg T. (2021): Lepraria lobificans (syn. L. santosii) and L. sylvicola new to northern Europe from Norway, Graphis Scripta, 33(3): 50–58

The two lichen species Lepraria lobificans (syn. L. santosii) and L. sylvicola are reported new to northern Europa, based on collections from Western Norway and Northern Norway, respectively. The specimens were identified by morphology, thin-layer chromatography, and the DNA barcode marker. The common species currently named L. lobificans in Northern Europe should be named L. finkii.

Harańczyk H., Strzałka K., Kubat K., Andrzejowska A., Olech M., Jakubiec D., Kijak P., Palfner G. & Casanova‑Katny A. (2021): A comparative analysis of gaseous phase hydration properties of two lichenized fungi: Niebla tigrina (Follman) Rundel & Bowler from Atacama Desert and Umbilicaria antarctica Frey & I. M. Lamb from Robert Island, Southern Shetlands Archipelago, maritime Antarctica, Extremophiles, 25: 267–283

Gaseous phase hydration properties for thalli of Niebla tigrina from Atacama Desert, and for Umbilicaria antarctica from Isla Robert, maritime Antarctica, were analyzed using 1H-NMR relaxometry, spectroscopy, and sorption isotherm analysis. The molecular dynamics of residual water was monitored to distinguish the sequential binding very tightly, tightly, and loosely bound water fractions. These two species differ in hydration kinetics faster for Desert N. tigrina [A1 = 0.51(4); t1 = 0.51(5) … Read more...

Tuovinen V., Millanes A.M., Freire-Rallo S., Rosling A. & Wedin M. (2021): Tremella macrobasidiata and Tremella variae have abundant and widespread yeast stages in Lecanora lichens, Environmental Microbiology, 23(5): 2484–2498

Dimorphism is a widespread feature of tremellalean fungi in general, but a little-studied aspect of the biology of lichen-associated Tremella. We show that Tremella macrobasidiata and Tremella variae have an abundant and widespread yeast stage in their life cycles that occurs in Lecanora lichens. Their sexual filamentous stage is restricted to a specific lichen: T. macrobasidiata only forms basidiomata on Lecanora chlarotera hymenia and T. variae only on Lecanora varia thalli. However, the yeast … Read more...

Wietrzyk-Pełka P., Rola K., Patchett A., Szymański W., Węgrzyn M.H. & Björk R.G. (2021): Patterns and drivers of cryptogam and vascular plant diversity in glacier forelands, Science of the Total Environment, 770: 144793 [14 p.]

Vascular and nonvascular plants are affected by environmental factors determining their distribution and shaping their diversity and cover. Despite the cryptogam commonness in Arctic communities, previous studies have often focused on limited number of factors and their impact on only selected species of vascular plants or cryptogams. Our study aimed to investigate in detail the differences in species diversity and cover of cryptogams and vascular plants in the glacier forelands and mature tundra … Read more...

Gholamhosseinian A., Sepehr A., Sohrabi M. & Emadodin I. (2021): Assessing the role of lichens in the prevention of dust emission in dryland: Case study at north-eastern Iran, Aeolian Research, 50: 100697 [11 p.]

The dominance of aeolian processes in arid areas created a harsh environment in these regions for soil and vegetation where soil fertility, ecosystem productivity, air clarity, and human health is dependent to aeolian activities and rate of dust emission. Biological soil crusts (bio-crusts) are the communities of living organisms on the soil surface which play an important role in soil ecosystem services in arid land. Lichens are known as organisms that can accumulate certain elements or substances … Read more...
