Baugh M & Leavitt S. (2022): Investigating potential factors influencing shifting lichen distributions—a case study of the maritime sunburst lichen (Xanthoria parietina) on a university campus in the Great Basin, Evansia, 39(3): 115–122

There are growing numbers of lichens observed outside their expected distributions. A recent discovery of Xanthoria parietina in Provo, Utah, USA is added to that list. Other individuals of this species have been noted in inland western United States, but this specimen was believed to be the first sighting of X. parietina in the Great Basin. Herbaria records were investigated for distribution data for other collections of X. parietina outside of their typical habitat. The identity of this unexpected … Read more...

McCune B. & Stone D.F. (2022): Eight new combinations of North American macrolichens, Evansia, 39(3): 123–128

Eight new taxonomic combinations are made for macrolichens that occur in North America. These combinations attempt to improve the practicality of taxonomic revisions resulting from molecular systematics. The new combinations are in the genera Bryoria, Cetraria, Peltigera, Scytinium, and Sulcaria. Key words. Lichens, Ahtiana, Bryoria, Cetraria, Peltigera, Scytinium, Sulcaria. Read more...

Morris C. & Stone D. (2022): Nephroma orvoi in western North America, Evansia, 39(3): 82–86

The recently described species Nephroma orvoi is part of the Nephroma parile complex. Both species are generally medium to dark brown, with rounded, smooth to distinctly foveolate lobes bearing sorediate to isidiate propagules. The best distinguishing character morphologically is the location of propagule formation. On N. orvoi they originate laminally while on N. parile they originate marginally. However, TLC provides the most accurate identification results, as the two species differ in terpenoids. … Read more...

Lee B.G. & Hur J.-S. (2022): A new species and four new records of Bacidia (Lecanorales, Ramalinaceae) from South Korea, with a key to Korean species, Mycokeys, 93: 107–130

A new species, Bacidia fuscopallida Lee & Heo and four new records, B. ekmaniana R. C. Harris, Ladd & Lendemer, B. friesiana (Hepp) Körb., B. heterochroa (Müll. Arg.) Zahlbr. and B. suffusa (Fr.) A. Schneid., are described from South Korea. Bacidia fuscopallida differs from B. diffracta S. Ekman, the most similar species, by warted but non-granular thallus, paler and smaller apothecia without pruina, proper exciple without crystals, over 11-septate ascospores and smaller pycnidia and pycnoconidia. … Read more...

Halıcı M., Güllü M., Kahraman Yiğit M. & Barták M. (2022): Three new records of lichenised fungi for Antarctica, Polar Record, 58: e22 [10 p.]

As part of a project aiming to determine the lichenised fungal biodiversity of James Ross Island (Eastern coast ofAntarctic Peninsula), we identified three infrageneric taxa which were previously not reported from Antarctica: Farnoldia micropsis (A. Massal.) Hertel, Gyalolechia epiphyta (Lynge) Vondrák and Placidium squamulosum var. argentinum (Räsänen) Breuss. Detailed morphological and anatomical properties of these species along with photographs based on the Antarctic specimens are provided … Read more...

Fávaro A., Demetrio G.R. & Coelho F.F. (2022): Size-dependent reproductive investment in a tropical cyanolichen, Bryologist, 125(4): 507–512

Reproductive strategies in lichens are a rarely studied field, and little is known about which variables affecting the production of reproductive structures are most important. Here, we investigated how lichen size and cardinal direction affected the density of apothecia in the cyanolichen Leptogium marginellum. We hypothesized that larger thalli and thalli facing south (towards the pole) would have a higher density of apothecia. Individuals with larger body sizes may store more resources that can … Read more...

Urbanska N., Simko P., Leskanicova A., Karasova M., Jendzelovska Z., Jendzelovsky R., Rucova D., Kolesarova M., Goga M., Backor M. & Kiskova T. (2022): Atranorin, a secondary metabolite of lichens, exhibited anxiolytic/antidepressant activity in Wistar rats, Life, 12(11): 1850 [13 p.]

Atranorin (ATR) is one of lichens’ many known secondary metabolites. Most current studies have investigated the various effects of ATR in vitro and only sporadically in vivo. The latest data indicate that ATR may have anxiolytic/antidepressive effects. This study aimed to analyze the potential of ATR in a depression-like state in male Wistar rats. Pregnant females were stressed by restricting their mobility in the final week of pregnancy three times a day for 45 min each, for three following days. … Read more...

Porada P. & Giordani P. (2022): Do lichens and mosses drink from tree bark?, Frontiers for Young Minds, 10: 704022 [8 p.]

Lichens and mosses often live on tree branches in the forest canopy. They store large amounts of rain, fog, or dew, because they cannot reach water in the soil. However, we do not know what their most important source of water actually is. For example, is water uptake from wet bark important? This is hard to answer, because these lichens and mosses live high above us, so it is difficult to make direct measurements. Computer mathematical simulations can be useful to answer this question. We … Read more...
