Dietrich, M. & Bürgi-Meyer, K. 2010. Interesting saxicolous lichens at Tossen near Schimbrigbad in the UNESCO Biosphere Entlebuch (Canton of Lucerne, Central Switzerland). — Herzogia 23: 75–84.

The description of the interesting lichen flora of the rock habitat at Tossen complements the knowledge of saxicolous species in the UNESCO Biosphere Entlebuch. At an altitude of 1480 m 61 lichen species were observed inhabiting the rock. Caloplaca dichroa, C. pusilla and Fulgensia klementii are mentioned for the first time from Switzerland. Acrocordia conoidea, Diplotomma alboatrum, Fulgensia bracteata subsp. deformis, Lecanora agardhiana, Porina byssophila, Synalissa symphorea and Thelidium minimum are new to the canton of Lucerne. Further species, until now only rarely registered in Switzerland, are mentioned specially, among them Lecanora reuteri, Naetrocymbe saxicola and Squamarina lamarckii. The documented lichen flora is very similar to comparable places at Mount Pilatus, from where the occurrence of Dacampia hookeri, Lecanora admontensis and Leucocarpia biatorella is mentioned for the first time from the canton of Lucerne.

Lüth, M. 2010. Ecology and phytosociology of Orthotrichum rogeri. — Herzogia 23: 121–149.

The epiphytic moss species Orthotrichum rogeri is endemic for Europe, therefore listed in Appendix II of the FFH directive. The species can be found in several regions of Europe, but is rare or very rare in all localities. In Southern Black Forest, O. rogeri has one of its centres of distribution, its ecology and phytosociology was studied there. Based on systematic mapping of 150 occurrences of that species and related site descriptions, conclusions were drawn about several site characteristics. Investigated parameters were topographical localisation in the landscape, exposure of microsites, position of the moss colonies on the carrier tree, and species and d.b.h. (Diameter at breast height) of the carrier trees. For 62 trees the pH-value of the bark was measured, and for 66 occurrences phytosociological relevés were recorded. Based on that, the phytosociology of O. rogeri was analysed. With respect to the site, it appears that cold air drainage and therefore cool nights are essential for the occurrence of that moss species.

From the wine-growing district Saale-Unstrut in southern part of Saxony Anhalt and the neighbouring parts of Thuringia and Lower Saxony the basiphytic association Didymodonto vinealis-Tortuletum muralis is described.

Syntaxonomy, sociological structure (with 2 vegetation tables), ecological behaviour and distribution of this community are described.
