[in German] The lichens of the oak park: even small urban parks can be ecologically valuable. Im Eichenpark in Hamburg-Harvestehude werden 55 borkenbewohnende Flechtenarten sowie 16 Arten auf Gestein nachgewiesen. Das nur 2 ha große Areal am westlichen Ufer der Alster unmittelbar an der Einmündung in die Außenalster weist eine für die Hamburger Innenstadt bemerkenswert hohe Vielfalt auf und belegt damit den Wert selbst kleinerer städtischer Parkanlagen als Refugien überwiegend licht- und … Read more... 

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... 

Four species of the genus Sticta are described as new from Bolivia, based on morphological examination and phylogenetic analysis of the fungal ITS barcoding marker. Additionally, two species are reported as new to Bolivia (their identification confirmed by molecular data) and one previously reported species is confirmed by molecular data for the first time. Detailed morphological and anatomical descriptions are provided for all new species. Two of the new species, S. isidiolobulata Ossowska, … Read more... 

Environmental toxins pose significant threats to ecosystems and human health. Monitoring and assessing these toxins are crucial for effective environmental management and public health protection. Recently, plant species have garnered increasing attention as potential bioindicators for identifying and evaluating ecological toxins. Since plants often come into touch with harmful compounds in soil, water, and the atmosphere, they are particularly valuable for analyzing how human activities influence … Read more... 

Phyllopsoraphaeophysciae sp. nov., having a lichenicolous habitat is growing on thallus of lichen Phaeophyscia and distinguished by white prothallus, globose to cylindrical isidia and thallus containing atranorin. Based on the previously published literature, Phylloposra species mostly reported to grow on bark, rock, soil and sometimes in association of mosses, however the new taxa is exhibit a unique lichenicolous habitat, luxuriantly growing on Phaeophyscia hispidula species in temperate region … Read more...
