González-Fuente I. & Ariño A.H. (2026): Fitness for purpose of reactive nitrogen monitoring methods in ecosystems: A multi-faceted comparative assessment, Environments, 13(8): 452 [27 p.]

Anthropogenic reactive nitrogen (Nr) production now greatly exceeds natural creation, generating cascading environmental impacts on the environment and human health. Effective monitoring of Nr in ecosystems is essential for early warning and policy response, yet the landscape of available monitoring methods is wide and heterogeneous, varying substantially in accuracy, purpose, cost, and ecological scope. This study evaluates nineteen Nr-monitoring methods, grouped into chemistry-based (CM), biodiversity-based … Read more...

Spielmann A.A., Marcelli M.P., Canêz L.S. & Benatti M.N. (2026): Parmotrema (Parmeliaceae, lichenized Ascomycota) with alectoronic acid: two new species, a checklist and a preliminary worldwide key, Plant and Fungal Systematics, 71(1): 250–269

A preliminary study of the Parmotrema species with alectoronic acid revealed a list of 63 such species worldwide. Two of these are newly described here, Parmotrema columnatum, with inflated apothecial stipes, and Parmotrema marginatihiatum, with abundant lobules, both from Brazil. A checklist with the main literature for each species and a working key are presented together with some illustrations of types or fresh collections, mainly from Brazil. Key words: Brazil, lichens, Parmelia, UV test. Read more...

Kalb K., Schumm F., Moncada B. & Lücking R. (2026): Malmidea aptrootiana (Malmideaceae), a new large-spored species in the Malmidea granifera complex, Plant and Fungal Systematics, 71(1): 242–249

The new species Malmidea aptrootiana is described from the Dominican Republic. It forms part of the M. granifera complex in having a verrucose thallus (medulla whitish, K+ yellow) and apothecia with a dark hypothecium and with an excipulum containing a medullary layer. Within this complex, the new taxon stands out by its comparatively large ascospores (19–27 × 10–12 μm). Only three species in this complex have larger ascospores: M. indica and M. subindica (28–40 × 12–24 μm), both … Read more...

Will-Wolf S., Umaña-Tenorio L., Chaves J.L., Nelsen M.P., Sipman H.J.M. & Lücking R. (2026): Gymnographopsis aptrootiana (Graphidales), a new addition to a poorly known genus with unique morphological features, Plant and Fungal Systematics, 71(1): 232–241

The new species Gymnographopsis aptrootiana is described from tree bark in rain forests of Costa Rica and Guyana. It is placed in Gymnographopsis based on the combination of a partially ecorticate thallus, lirellate ascomata with partly exposed disc, and small, non-amyloid (I–), septate ascospores. Overall, it is most similar to G. koreaiensis, but differs in the 1-septate ascospores and the formation of disc-shaped schizidia, as well as its unusual chemistry with three unidentified compounds. … Read more...

Weerakoon C., Wolseley P., Vairappan C., Thüs H. & Lücking R. (2026): Graphidaceae from Sabah (NE Borneo), including eight new species, Plant and Fungal Systematics, 71(1): 205–222

Graphidaceae is one of the largest families of lichenized fungi, with over 2,300 species in 80 genera known and about 3,600 species predicted. The Eastern Paleotropics constitute one of the hotspots of Graphidaceae diversity, including many potentially unknown species awaiting discovery. The Malaysian state of Sabah in NE-Borneo is home to some of the oldest continuously forested areas in SE-Asia, but only a few recent studies sampled Graphidaceae, particularly in the remaining pockets of lowland … Read more...

Miranda-González R., Lücking R., Herrera-Campos M.A. & Campos-Cerda F. (2026): Alloarthopyrenia aptrootiana sp. nov. (Trypetheliaceae), the second recognized species in the genus and the first tropical member of Alloarthopyrenia, with a revised taxonomic concept for Arthopyrenia cinereopruinosa, Plant and Fungal Systematics, 71(1): 192–204

We describe the new species Alloarthopyrenia aptrootiana from western Mexico, representing the second known species in the genus and its first tropical member. The new species is characterized by its narrow, 1-septate ascospores of 17–21 × 6–7.5 μm, with additional strong constrictions in the middle of each cell. We present a phylogeny of Trypetheliaceae that confirms the position of the new species in the genus. We propose the new combination Naetrocymbe cinereopruinosa to accommodate … Read more...

de Lange P.J., Moncada B., Blanchon D., Ranft H. & Lücking R. (2026): The Pseudocyphellaria hookeri clade (Peltigerales): a species pair-photosymbiodeme speciation complex?, Plant and Fungal Systematics, 71(1): 164–191

We present an integrative taxonomic revision of the Pseudocyphellaria hookeri group in Aotearoa | New Zealand. Molecular data of the fungal ITS barcoding marker resolve the group as monophyletic, in a strongly supported clade on a long stem branch, related to the P. crocata group. Our study confirms the three species previously assigned to this group, P. hookeri, P. durietzii, and P. montagnei, as part of this clade. In addition, a fourth species was detected and is formally described here, … Read more...

Kraichak E., Lücking R.,, Moncada B., Flynn T.W., Smith C.W. & Lumbsch H.T. (2026): Remarkable diversification of the lichenized genus Fissurina (Graphidales) in Hawai‘i, Plant and Fungal Systematics, 71(1): 122–163

We present a molecular phylogenetic and taxonomic revision of the genus Fissurina (Graphidales) in Hawaiʻi. Compared to eight previously reported species, we distinguish a total of 26 species. Only four of the previously reported species are tentatively confirmed, namely F. columbina, F. globulifica, F. stromatoides, and F. zahlbruckneriana. An additional four species are new records for the archipelago, including F. consentanea, F. crassilabra, F. deficiens, and F. hyalinella. The following … Read more...

Sipman H.J.M., van den Boom P. & Rodrigues F.A. (2026): Which Ramalina species occur on the Azores? An approach using TLC and ITS barcoding sequences, Plant and Fungal Systematics, 71(1): 97–121

The lichen genus Ramalina is well represented on the Azores islands, an isolated archipelago in the Atlantic Ocean. Fieldwork on several islands, loans from several herbaria, and the collecting of fresh samples, allowed us to identify lichen substances by TLC and to estimate the phylogenetic placement of taxa using ITS sequences from many samples. This confirmed the presence of 13 species, including R. portuensis as new to the Azores and new to Greece. Evidently the Ramalina biota of the Azores is … Read more...

Diederich P., Ertz D. & Timdal E. (2026): Coccocarpia aptrootii, a new lichen species from Mauritius, Plant and Fungal Systematics, 71(1): 91–96

A new species of Coccocarpia is described from Mauritius based on morphological and molecular evidence. The species is corticolous and currently known from four localities in parkland and natural mountain forest habitats. It is characterized by comparatively large thallus lobes, a distinctly pruinose upper surface, and abundant laminal isidia that are initially subspherical and later elongate into cylindrical to coralloid structures. Phylogenetic analysis of nuclear ITS rDNA sequences places the … Read more...
