Ertz D., Diederich P., Lendemer J., Komposch H., Harris R.C. & Huereca A. (2023): A remarkable and widespread new lichenicolous species of Mycocalicium (Sphinctrinaceae) producing campylidia-like conidiomata and appendiculate conidia - Plant and Fungal Systematics, 68(2): 411–423

A lichenicolous fungus forming large black, vertically elongate, campylidia-like conidiomata on the thallus of Ochrolechia was recently collected in Austria, Mexico and the USA. The conidia are so remarkable in being multiappendiculate that initially no existing fungal genera appeared to be suitable for its description. Nevertheless, molecular phylogenetic analyses of nuITS and nuLSU sequences recovered the species within the genus Mycocalicium. To date, no species of Mycocaliciales has been … Read more...

Robison A., Adams P. & Leavitt S.D. (2023): Discovering neglected lichen diversity with DNA-based inventories: metabarcoding lichen-forming fungi in Bryce Canyon National Park, Utah, USA - Plant and Fungal Systematics, 68(2): 395–410

National parks and other federally designated natural areas play critical roles in preserving unique habitats, communities, and biodiversity. However, in the United States, it is estimated that 80–90% of species diversity in national parks is presently unknown. Therefore, contemporary biodiversity inventories are critical for conservation, management and establishing baselines for future comparisons. Ongoing efforts to characterize lichen diversity highlight diverse and robust communities … Read more...

Poncet R., Meyer J.-Y., Paradis A.-H., Leblond S. & Kervran L. (2023): A new species of Agonimia (Ascomycota, Eurotiomycetes, Verrucariaceae) from Morane atoll (Tuāmotu-Gambier Islands, French Polynesia) - Plant and Fungal Systematics, 68(2): 388–394

Agonimia gargominyi (Verrucariaceae, Verrucariales) is described and illustrated from bark samples collected from Morane atoll (Tuāmotu-Gambier Islands, French Polynesia). It is characterized by the large superficial perithecia having a pale brown-colored ostiolar region, the 8-spored asci, and the relatively large lobed squamules. Micromorphology of the ascomata and the thalline squamules matches the genus Agonimia. Additionally, to accommodate the inclusion of this newly identified species, … Read more...

Fryday A.M. (2023): Lecanora (Aspicilia) masafuerensis is a species of Xenolecia (Ascomycota, Lecideaceae) - Plant and Fungal Systematics, 68(2): 382–387

The new combination Xenolecia masafuerensis is made for Lecanora masafuerensis, a lichen species known from only two localities on Isla Alejandro Selkirk in the Juan Fernández archipelago, Chile. The species is fully described and illustrated and shown to be morphologically and chemically distinct from the similar X. spadicomma, which is known only from Chile and the Falkland Islands. The typification of X. masafuerensis and its distribution on the islands are also discussed. Key words: distribution, … Read more...

Jørgensen P.M. & Schmitt I. (2023): The typification of Variolaria discoidea Pers. - Plant and Fungal Systematics, 68(2): 378–381

The type species of the lichen genus Variolaria is V. discoidea. The name is solely based on a Hoffmann (1784) illustration. To stabilize the nomenclature, we have designated a lectotype and an epitype from Germany, for which we generated molecular data. The species was formerly placed in the genus Pertusaria as P. albescens, and is presently correctly named Lepra albescens. Key words: lichens, nomenclature, Pertusariales, taxonomy. Read more...

Westberg M., Ekman S., Briegel-Williams L., Fernandez-Brime S., Wedin M. & Timdal E. (2023): Thalloidima squamatum comb. nov. – a distinct and common but overlooked lichen in Europe - Plant and Fungal Systematics, 68(2): 353–363

The new combination Thalloidima squamatum is proposed for a morphologically and phylogenetically distinct species, until now included within the variation of T. sedifolium. Compared to T. sedifolium, the species is characterized by its larger squamules and apothecia, shorter ascospores, the pale color of the excipulum, and its habitat growing on moss cushions over calcareous rock or directly on rock rather than on soil. Most of the material studied originates from Norway and Sweden, but specimens … Read more...

Clerc P. & Ohmura Y. (2023): Notes on the genus Usnea (lichenized Ascomycota, Parmeliaceae). V. - Plant and Fungal Systematics, 68(2): 340–352

Type material of twelve species of Usnea related to Asia and South Africa were studied and one species from North America is newly described. Holotype specimens of eight Chinese taxa described in 1975 were synonymized as follows: U. mengyangensis is lectotypified and synonymized with U. aciculifera. Usnea recurvata and U. subrectangulata are synonymized with U. baileyi. Usnea kirinensis is synonymized with U. barbata s.str. Usnea crassiuscula and U. yunnanensis (= U. australis J.D. Zhao et al., … Read more...

Lumbsch H.T., Morris C. & McCune B. (2023): A new species of Diploschistes (Lecanoromycetes) occurring on Stereocaulon from the Pacific Northwest of North America - Plant and Fungal Systematics, 68(2): 335–339

We describe Diploschistes stereocaulorum as a new species of lichenized fungi growing on phyllocladia and stalks of Stereocaulon in the Pacific Northwest of North America. The larger ascospores of this species, the absence of a noticeable thallus, and the ITS barcode locus distinguish it from D. muscorum, which has been reported as growing on Stereocaulon, but has smaller ascospores and a distinct thallus. In phylogenetic reconstruction, the new species is sister to D. diacapsis, albeit without … Read more...

Sipman H. & Aptroot A. (2023): Fourteen new Carbacanthographis species from the Neotropics, with ecological observation - Plant and Fungal Systematics, 68(2): 320–334

A revision of neotropical specimens of the genus Carbacanthographis (Graphidaceae, lichenized fungi) revealed the presence of 14 undescribed species: Carbacanthographis bulbosa, C. clandestinospora, C. cristata, C. denudata, C. granulosa, C. inspersomarcescens, C. isidiata, C. latisporoides, C. lucidocleitops, C. minutissima, C. multiseptatoides, C. nigra, C. nitida, and C. protocristata. They are presented below. The genus appears to have a diversity center in semideciduous forests of northern … Read more...

Søchting U., Sancho L.G. & Arup U. (2023): The lichen genera Gondwania and Transdrakea gen. nov. (Teloschistaceae) – speciation in three southern continents - Plant and Fungal Systematics, 68(2): 304–319

Within the lichen family Teloschistaceae, a high number of genera are restricted to the extreme southern part of the Southern Hemisphere. The taxonomy and phylogeny of the southern genus Gondwania have been analyzed based upon fieldwork in Antarctica, Patagonia, New Zealand and Tasmania and subsequent studies including molecular methods. Five species are accepted in the genus Gondwanea including G. inclinans and G. joannae that are combined into the genus. Two species are included in the neighboring … Read more...
