Din A.U., Iqbal M.S., Khalid A.N. & Niazi A.R. (2024): Chlorangium ahmadii sp. nov. and Circinaria darelensis sp. nov. two new species of lichenized Ascomycetes from Pakistan, Plant Systematics and Evolution, 310: 13 [8 p.]

Chlorangium ahmadii sp. nov. and Circinaria darelensis sp. nov. are described as new species from Pakistan. A comparative morpho-anatomical, chemical study and ITS-based molecular analyses confrmed the positions of these species within the genera Chlorangium and Circinaria. Chlorangium ahmadii sp. nov. difers from its closely related species, C. alpicola in having light brown to whitish-brown thallus (vs. brownish-grey to greyish-green), fat to concave apothecial disc (vs. concave to convex … Read more...

Fryer E.R., Mulroy M., Hodge C., Eulensen-Wallace J.E., Dart J. & Rajakaruna N. (2024): A preliminary exploration of an understudied lichen flora: Lichens of the basin of Carrizo Plain National Monument, California, Evansia, 41(2): 35–46

While Carrizo Plain (California, USA) is a hotspot for rare and endangered species, little effort has been made to sample the lichen flora of the Plain. To assemble a preliminary checklist of lichens from the basin floor of Carrizo Plain, we sampled along a transect from the basin’s alkali complex to its western edge, as well as from clay slickspots with high sodium content, and a rocky site in the eastern Plain. We document a substantial lichen flora on the Plain and note several collections … Read more...

He Z., Naganuma T., Nakai R., Uetake J. & Hahn M.W. (2024): Microbiomic analysis of bacteria associated with rock tripe lichens from alpine areas in eastern Alps and equatorial Africa, Current Microbiology, 81: 115 [17 p.]

The diversity of bacteria associated with alpine lichens was profiled. Lichen samples belonging to the Umbilicariaceae family, commonly known as rock tripe lichens, were gathered from two distinct alpine fellfelds: one situated on Mt. Brennkogel located in the Eastern European Alps (Austria), and the other on Mt. Stanley located in the Rwenzori mountains of equatorial Africa (Uganda). The primary aim of this research was to undertake a comparative investigation into the bacterial compositions, and … Read more...

Hekkala A.-M., Jönsson M., Kärvemo S., Strengbom J. & Sjögren J. (2023): Habitat heterogeneity is a good predictor of boreal forest biodiversity, Ecological Indicators, 148: 110069 [14 p.]

Reliable assessment measures are crucial for tracking changes in biodiversity and for evaluating the state of biodiversity. Two of the main drivers of biodiversity are habitat heterogeneity and resource amount. These drivers are used as proxies of biodiversity but assessing both is costly, limiting their practical use. To test which of the drivers best predicts the number and abundance of sessile species of conservation concern (including macrofungi, lichens, bryophytes, and vascular plants), … Read more...

Hirschheydt G. von, Kéry M., Ekman S., Stofer S., Dietrich M., Keller C. & Scheidegger C. (2024): Occupancy model reveals limited detectability of lichens in a standardised large-scale monitoring, Journal of Vegetation Science, 35: e13255 [11 p.]

Question: What are the extent and the possible causes of imperfect detection in lichens? Because lichens are sessile and lack seasonality, they should be easier to survey than animals that can move or plants and fungi with seasonal morphology, and one could therefore expect relatively high detection probabilities. Location: 826 standardised sampling plots across Switzerland. Methods: Using repeated detection/non-detection data from a national lichen survey conducted by professional lichenologists, … Read more...

Chen Y.-X., Wang L.-B., Xie Y.-H., Guo S.-Y. & Han L.-F. (2023): Usnea jingdongensis sp. nov. from Southwest China, Mycotaxon, 137(4): 913–927

Usnea jingdongensis from the Ailaoshan Mountain of Southwest China, is described as a new species of Parmeliaceae. It is characterized by the uninflated branches, fistulose axis with pale brown to dark brown loose hyphae, and the absence of pseudocyphellae and soralia. The phylogenetic analysis of the nrDNA ITS sequence data supported the recognition of the species. A key to the eumitrioid Usnea species in China is also provided. Key words: Asia, evolutionary tree, Lecanorales, protocetraric acid, … Read more...

Khodosovtsev A. & Kuzemko A. (2023): First records of Anema nodulosum, A. tumidulum, and Pyrenocarpon thelostomum (Lichinales, Lichinaceae) in Ukraine and a contribution to Collematetea cristati communities, Український ботанічний журнал [Ukrainian Botanical Journal], 80(1): 98–107

Three new for Ukraine species, Anema tumidulum, A. nodulosum, and Pyrenocarpon thelostomum (Lichinales, Lichinaceae), are reported. They were found in the Dnister Canyon, on the S and W exposed cliff surfaces where water tracks formed 'a black zone' of the Collematetea cristati class. Other species forming these communities are Anema decipiens, Psorotichia schaereri, Peccania coralloides, Thallinocarpon nigritellum, Thyrea confusa, and Verrucaria nigrescens s. l. The analyzed dataset included three … Read more...

Kocakaya M., Barak M.ü. & Kocakaya Z. (2023): New records of lichenicolous and lichenized fungi from Üzümdere Nature Park, Türkiye, Mycotaxon, 137(4): 943–951

Four species of lichenicolous fungi (Clypeococcum epicrassum, Polycoccum cladoniae, Sphaerellothecium arnoldii, and Stigmidium aff. lecidellae) and two species o f lichenized fungi (Gyalolechia klementii and Parvoplaca servitiana) are reported for the first time from Turkey. Comments on their morphological characters, habitats, and substrates are provided, together with macro- and microphotographs. Key words: biodiversity, lichens, Mycosphaerellaceae, Polycoccaceae, Teloschistaceae. Read more...

Motiejūnaitė J. (2024): Lithuanian lichens and lichenicolous fungi in the herbaria of the University of Tartu (Estonia) and the University of Latvia, Botanica, 30(1): 23–30

Herbarium collections are particularly significant in countries where systematic studies of specific taxonomic groups have not been carried out, such as in the case of lichens in Lithuania. Collections prior to the 1990s are scarce, so all historical material is of great value. This paper presents the results of a study of lichen collections in the herbaria of the University of Tartu (TU) and the University of Latvia (RIG). A total of 425 herbarium envelopes (84 RIG and 341 TU) were examined. A total … Read more...

Usman M., Dyer P.S., Brock M., Wade C.M. & Khalid A.N. (2024): Two novel species of arctic-alpine lichen-forming fungi (Ascomycota, Megasporaceae) from the Deosai Plains, Pakistan, MycoKeys, 102: 285–299

Members of the lichen-forming fungal genus Oxneriaria are known to occur in cold polar and high altitudinal environments. Two new species, Oxneriaria crittendenii and O. deosaiensis, are now described from the high altitude Deosai Plains, Pakistan, based on phenotypic, multigene phylogenetic and chemical evidence. Phenotypically, O. crittendenii is characterised by orbicular light-brown thalli 1.5–5 cm across, spot tests (K, C, KC) negative, apothecia pruinose, hymenium initially blue then dark … Read more...
