Ahmad N., Ritz M., Calchera A., Otte J., Schmitt I., Brueck T. & Mehlmer N. (2023): Biosynthetic potential of Hypogymnia holobionts: insights into secondary metabolite pathways - Journal of Fungi, 9(5): 546 [16 p.]

Lichens are symbiotic associations consisting of a photobiont (algae or cyanobacteria) and a mycobiont (fungus). They are known to produce a variety of unique secondary metabolites. To access this biosynthetic potential for biotechnological applications, deeper insights into the biosynthetic pathways and corresponding gene clusters are necessary. Here we provide a comprehensive view of the biosynthetic gene clusters of all organisms comprising a lichen thallus: fungi, green algae, and bacteria. We … Read more...

Wyczanska M., Wacker K., Dyer P.S. & Werth S. (2023): Local-scale panmixia in the lichenized fungus Xanthoria parietina contrasts with substantial genetic structure in its Trebouxia photobionts - The Lichenologist, 55(2): 69-79

Microsatellite markers can provide valuable information about gene flow and population history. We developed and tested new microsatellites for the nitrophilic lichenized fungus Xanthoria parietina and studied its genetic diversity and structure within the urban area of Munich, Bavaria. We compared its local genetic pattern with that of its photobiont partner Trebouxia decolorans, for which existing microsatellites were applied. For comparison, a reference site with clean air was included in the … Read more...

Ansil P., Rajeshkumar K., Sharma B., Lücking R. & Hawksworth D.L (2023): Phylogenetic placement and reappraisal of Diorygma karnatakense including the new synonym, Diorygma dandeliense, from Maharashtra, India - The Lichenologist, 55(2): 59-67

This study re-examined the status of species of Diorygma Eshw. known from the Western Ghats using an integrative taxonomy approach that includes morphological and chemical data, as well as multigene phylogenetic analyses. Prior to this work, the two species D. karnatakense and D. dandeliense were distinguished primarily on lirellae morphology (branching pattern) and the number of ascospores per ascus. Our study of the morphology, chemistry and molecular phylogeny (mtSSU, LSU and RPB2) of freshly … Read more...

Afshan N., Fayyaz I., Iftikhar F., Jabeen M. & Khalid A. (2023): A new species and a new record of the genus Squamulea (Teloschistaceae, lichenized Ascomycota) from Pakistan - The Lichenologist, 55(2): 51-58

A novel species in the genus Squamulea, S. chikarensis, is described from Himalayan moist temperate forest in Pakistan. The morphology, chemistry and ITS sequences support its distinction from other species of this genus. The taxon is characterized by a pale green to yellow thallus, large apothecia up to 0.8–1.8 mm wide, pale yellow to yellow-orange apothecial discs, a hymenium 70–110 μm high, large ascospores (12–20 × 5–11 μm) and a narrow ascospore septum (1.5–3 μm). In addition, … Read more...

Khalid A.N. & Zulfiqar R. (2023): A new species of the genus Verrucaria (lichenized Ascomycetes: Verrucariaceae) from Kohistan district, Pakistan - Plant Systematics and Evolution, 309: 18 [6 p.]

Verrucaria pakistanica is described as a novel species from District Kohistan, Khyber Pakhtunkhwa Province. It is characterised by thick, deeply areolate thallus, large superfcial perithecia, a thick involucrellum (80–105 µm), i.e., conical, not reaching the substratum and larger ascospores (20–29×7–10 µm) than the similar V. muralis. Phylogeny of ITS and nuLSU region confrms its position within the genus Verrucaria and morphological comparison makes it distinct from other related species … Read more...

Melekhina E.N. (2023): Lichen-associated oribatid mites in the taiga zone of northeast European Russia: taxonomical composition and geographical distribution of species - Diversity, 15(5): 599 [20 p.]

We examined 35 species of ground and epiphytic lichens, including fruticose, foliose, and crustose lichen, as habitats of oribatid mites. Observations were carried out in the taiga forests of northeast European Russia, and 87 oribatid species from 38 families were found. The Crotoniidae, Carabodidae, Oppiidae, and Suctobelbidae are the most numerous families in ground lichens and the Oribatulidae are in the epiphytes. The families Micreremidae and Licneremaeidae were only noted in epiphytes. A complex … Read more...

Healthy forests are essential to human life because they provide food, energy, and other benefits including carbon sequestration. The objective of this study was to assess the forests health status in Mediterranean ecosystems, specifically, arid to semi-arid. Four forest reserves directed by Royal Society for the Conservation of Nature, Jordan were evaluated. Plant health indicators [(gas exchange (photosynthesis, stomatal conductance, transpiration), chlorophyll, middy stem water potential (Ψsmd), … Read more...
