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...

Arup U., Søchting U. & Halıcı M.G. (2023): Four new species of Parvoplaca (Teloschistales, Ascomycota) - Plant and Fungal Systematics, 68(2): 294–303

The genus Parvoplaca is extended with four new species: P. candanii from Antarctica, P. lamprocarpa from Alaska, and P. macroborealis and P. tenebrosa from Oregon. Collections identified as P. tiroliensis are shown to form two independent clades when DNA was analyzed, but it is currently not clear which clade represents the species in a strict sense. Parvoplaca athallina has been considered an Antarctic species, but according to our analyses, the species is shown to be bipolar occurring also … Read more...

Palice Z., Svoboda S. & Vondrák J. (2023): Hidden in the dark under umbrellas: two new Psilolechia species (lichenized Ascomycota, Lecanorales) described from the Czech Republic - Plant and Fungal Systematics, 68(2): 285–293

Recent lichenological fieldwork in the Czech Republic resulted in the discovery of two previously unrecognized entities in the genus Psilolechia which are described below as new species: the saxicolous P. cretacea and the lignicolous P. torii. Both taxa regularly produce a hyphomycetous anamorph in the form of erect, elongate conidiogenous cells on the thallus surface, and both contain unidentified specific secondary metabolites. The placement of the two new species within the genus is primarily … Read more...

Ekman S. (2023): Bacidia genuensis B. de Lesd. resurrected - Plant and Fungal Systematics, 68(2): 280–284

The species described as Bacidia genuensis is transferred here to Bacidina as B. genuensis (Ramalinaceae, Lecanorales, lichenized Ascomycota). An updated morphological description is provided. The species is characterized by mostly blackish apothecia on a thick, microsquamulose thallus, a crystal-inspersed proper exciple that is mostly prosoplechtenchymatous, an ascus with a wide and dome-shaped axial body and an expanded c-layer (resulting in a thin, amyloid d-layer), a blue-green pigment in … Read more...

Printzen C., Holien H., Kantelinen A., Myllys L., Ratschow F., Stepanchikova I., Weber L. & Timdal E. (2023): DNA barcoding indicates the presence of unrecognized species and phylogenetic diversity within the Biatora vernalis- and B. meiocarpa-groups - Plant and Fungal Systematics, 68(2): 262–279

The Biatora vernalis- and meiocarpa-groups comprise species with pale beige to reddish brown apothecia and 0-, rarely also 1(–3)-septate ascospores. A DNA barcoding approach based on ITS sequences shows that these two groups comprise more species and phylogenetic diversity than previously known. Specimens identified as B. vernalis, the type species of the genus, appear to be paraphyletic with regard to B. chrysantha. In addition, there is a morphologically similar species belonging to the … Read more...

Aptroot A., Lücking R. & Cáceres M.E.S. (2023): New species and records of Graphidaceae and Gomphillaceae (lichenized fungi) from Brazil - Plant and Fungal Systematics, 68(2): 249–261

We describe 14 new lichen species in the family Graphidaceae, mainly from the Amazon basin: Acanthothecis aggregata, Allographa ancelina, A. apicalinspersa, Chapsa constrictospora, C. diorygmoides, C. lichexanthonica, Clandestinotrema caloplacosporum, Diorygma defectoisidiatum, D. gyrosum, D. lichexanthonicum, D. norsubmuriforme, D. salxanthonicum, D. toensbergianum, and Ocellularia flavoradiata. For each species, it is indicated where and how it would key out in a recent identification key. … Read more...
