Wirth, V. & Kondratyuk, S. Y. 2010. New species of the lichen family Teloschistaceae from the Namib Desert and the Succulent Karoo (SW-Africa). — Herzogia 23: 179–194.
Five new species of the genus Caloplaca (C. albocrenulata, C. gypsicola, C. renatae, C. subochrochroa and C. wesselsii) and one new Jackelixia-species (J. ottolangei) from the Namib Desert and the adjacent Karoo are described. The type of Caloplaca leucoxantha is investigated. A key of the hitherto known Caloplaca species of the Namib Desert is provided.
Brackel, W. v. & Berger, F. 2010. Gall-inducing species of Polycoccum (Ascomycota) on the lichen genus Placopsis. — Herzogia 23: 195–204.
Three new gall-inducing species of Polycoccum, all dwelling on hosts of the genus Placopsis, are described: Polycoccum deformans on Placopsis lambii and P. gelida, Polycoccum perrugosae on Placopsis perrugosa, andPolycoccum islandicum on Placopsis gelida. A key to the lichenicolous fungi currently known on Placopsis is presented.
Jabłońska, A. 2010. The lichen genus Porpidia in Poland III. — Herzogia 23: 217–228.
The taxonomy, chemistry, morphology, habitat requirements and distribution of Porpidia flavocruenta, P. grisea, P. macrocarpa, P. P. nigrocruenta, P. speirea and P. zeoroides from Poland are detailed. Porpidia flavocruenta is recorded for the first time for Poland and P. nigrocruenta is new to Ukraine. Porpidia nigrocruenta is considered to be a distinct species. The occurrence of P. flavicunda, P. hydrophila and P. trullisata has not been confirmed during the study in Poland and the status of these taxa remains unknown. A key for taxa in Poland, including those with unconfirmed occurrence in the country, is provided.
Wirth, V. 2010. Ecological indicator values of lichens — enlarged and updated species list. — Herzogia 23: 229–248.
A new edition of the species list of ecological indicator values of lichens is presented. Values of the hitherto considered species have been checked and corrected where appropriate. Fifty-eight additional species have been included. Overall, indicator values for important climatic factors (light = L, temperature = T, continentality = K, moisture = F) and substrate properties (pH = R, eutrophication = N) are now available for 516 species. A procedure to assess the eco-climatic oceanity (KO) with the help of the indicator values is presented. Since the eco-climatic oceanity has a temperature and a moisture component, the indicator value of eco-climatic oceanity can be calculated with the formula KO = (10 - K F) : 2.
Bilovitz, R O., Stešević, D. & Mayrhofer, H. 2010. Epiphytic lichens and lichenicolous fungi from the northern part of Montenegro. - Herzogia 23: 249–256.
A list of 120 taxa of lichens (117 species) and three species of lichenicolous fungi from the northern part of Montenegro is presented. The lichens Biatora chrysantha, Caloplaca monacensis, Candelariella efflorescens, Loxospora elatina, Micarea adnata, Ochrolechia arborea, O. microstictoides, Phaeophyscia nigricans, Physconia enteroxantha, Ph. grisea, Rinodina capensis, R. polysporoides, R. pyrina, Scoliciosporum umbrinum var. corticolum, Xanthoria candelaria, X. ulophyllodes and the lichenicolous fungi Lichenodiplis lecanorae, Telogalla olivieri, and Xanthoriicola physciae are new to Montenegro.
Schramm, J. & Wollert, H. 2010. The bryophyte flora of an unspoiled percolation mire of northern Germany in the valley of the Blinde Trebel (Mecklenburg-Western Pomerania). — Herzogia 23: 257–267.
An extraordinary rich bryophyte flora can be found in one of the last unspoiled percolation mires of northern Germany in the valley of the Blinde Trebel south of Franzburg (Mecklenburg-Western Pomerania). The habitat has maintained its natural conditions nearly without any changes over the last five decades. A number of the existing plant communities, which are characterized by the highest contents of endangering, harvest a high degree of very rare and critically endangered mosses. Among them are especially the characteristic taxa of the Paludello palustris-Caricetum Succow 1974 Paludella squarrosa, Helodium blandowii, Tomentypnum nitens and Philonotis calcarea.
With the help of ecological indicator values the bryophytes contribute considerably to the habitat characterization of such mesotrophic calcareous mire.
Philippi, G. 2010. Epiphytic bryophyte vegetation on stems of Acer campestre in SW Germany and the eastern part of France. — Herzogia 23: 269–278.
The frequency of epiphytic bryophytes on the stems of Acer campestre in SW Germany and the eastern part of France (Alsace, northern part of Burgundy and southern part of Lorraine) was investigated. More than 130 stems were examined, all growing in forest communities. Isolated trees or trees growing along forest margins were not included. The diameter of the stems was mostly 0.2 to 0.3m. The average number of the observed species is 6 to 8 per stem. The bryophyte vegetation is often very luxuriant and grows on the stems not rarely up to 4 to 5m above the ground. The epiphytic bryophyte flora on Acer campestre is characterized by the dominance of neutrophytic and basiphytic species. Hypnum cupressiforme as an acidophil species was only rarely observed. The absence of Anomodon attenuatus in parts of Burgundy and Lorraine is remarkable. Distinctly different there is the epiphytic bryophyte flora on Acer campestre in areas with a higher air pollution in the Rhine area (western part of the Kaiserstuhl and the region of Mannheim — Ludwigshafen).
Marstaller, R. 2010. The bryophyte communities of the order Hylocomietalia splendentis Gillet ex Vadam 1990. 141th contribution to the bryophyte vegetation of Thuringia. — Herzogia 23: 279–311.
The acidophytic or subneutrophytic bryophyte communities Eurhynchietum striati Wiśn. 1930, Hylocomietum brevirostris ass. nov., Brachythecio rutabuli-Cirriphylletum piliferi ass. nov. and Pleurozietum schreberi Wiśn. 1930 has been described in Thuringia and neighbouring areas. These communities grows on a thin humus layer over rock, on living bark and on rotten wood in forests and margins of forests. Syntaxonomy, phytosociological structure (with 5 vegetation tables), ecology and distribution of these communities are described.
Brackel, W. v. 2010. Dacampia cyrtellae, a new name for Dacampia lecaniae Brackel. — Herzogia 23: 315–316.
The name Dacampia lecaniae Brackel is recognized as a later homonym of Dacampia lecaniae Kocourk. & K.Knudsen. As both species are distinct, a new name, Dacampia cyrtellae Brackel, is proposed here to replace Dacampia lecaniae Brackel.
