Kukwa, M. & Motiejūnaitė, J. 2012. Revision of the lichen genera Cetrelia and Punctelia (Lecanorales, Ascomycota) in Lithuania with implications for their conservation. — Herzogia 25: 5 –14.

A revision of all available specimens has shown that the genus Cetrelia in Lithuania is represented by two species, C. monachorum and C. olivetorum. One specimen belonged to Punctelia jeckeri. The distribution and status of both genera in Lithuania are reviewed, distribution maps are provided, and the merits of the segregates for conservation measures are discussed. Cetrelia monachorum and Punctelia jeckeri are reported for the first time from Lithuania and from the Baltic states.

Osyczka, P. 2012. The lichens of Cladonia, ‘supergroup’ Perviae, in Poland. — Herzogia 25: 15 –30.

This study based on the examination of approximately 1400 herbarium specimens from the members of Cladonia ‘supergroup’ Perviae deals with morphology, secondary chemistry, habitat requirements and distribution in Poland. Six taxa have been accepted for the Polish lichen biota, namely, C. cenotea, C. crispata var. crispata, C. crispata var. cetrariiformis, C. glauca, C. parasitica, and C. squamosa; the occurrence of the two previously reported species, C. strepsilis and C. subfurcata has not been confirmed. The chemical races of the species and their frequency in Poland are indicated and a key for the taxa of ‘supergroup’ Perviae is provided. Additionally, two species, C. caespiticia and C. scabriuscula, which are frequently confused with some species of Perviae, were included in the revision.

Dolnik, C., Schiefelbein, U., Schultz, M., de Bruyn, U. & Richter, T. 2012. New and noteworthy findings of lichenized and lichenicolous fungi from northern Germany. - Herzogia 25: 31–38.

Taxonomical revisions and new findings led to some additions to the lichen floras of the Northern German federal states Lower Saxony, Mecklenburg-Western Pomerania and Schleswig-Holstein, which are also relevant for the German checklist. We comment on records of 19 lichenized, two lichenicolous and one saprophytic fungus. Amandinea lecideina is reported from Germany for the first time after more than 50 years. Trimmatothelopsis versipellis (syn. Acarospora amphibola) is treated as a species distinct from T. smaragdula with a strong preference for coastal habitats. The following species were added to the lichen flora of the federal state Mecklenburg-Western Pomerania: Caloplaca maritima, C. phlogina, Gregorella humida, Illosporiopsis christiansenii, Lecanora persimilis, L. zosterae, Micarea byssacea, M. micrococca, Porina leptalea and Scoliciosporum gallurae. New to Schleswig-Holstein are Micarea botryoides and Polyblastia dermatodes.

Aptroot, A. 2012. Changes in the epiphytic flora on four Tilia trees in Belgium over 59 years. — Herzogia 25: 39 – 45.

The epiphytes on four Tilia trees in southern Belgium, which were studied by Barkman in 1952, were re-investigated in 1999 and 2011. In 1952, 19 species of epiphytes (including 12 lichen species) were recorded; in 1999, there were 65 epiphyte species (including 49 lichens), and in 2011, 53 epiphyte species (including 41 lichens) were found. The enormous increase in species between 1952 and 1999 is primarily attributable to colonization by additional species, which is an early stage of natural succession, whereas the reduction in species between 1999 and 2011 is most probably due to competition, the next step in the natural succession, when larger mosses and foliose lichens became dominant over crustose lichens and the whole bark surface had been covered by epiphytes. Global warming also may have influenced the species composition in the last decades.

HAFELLNER, J. & ZIMMERMANN, E. 2012. A lichenicolous species of Pleospora (Ascomycota) and a key to the fungi invading Physcia species. — Herzogia 25: 47–59.

The new combination Pleospora physciae (BRACKEL) Hafellner & E.Zimm. (bas. Merismatium physciae BRACKEL 2010) is introduced. An emended description is given and the species, which is a pathogen on various epiphytic Physcia species is newly reported for the mycoflora of Austria, Slovenia and Switzerland. Two further nomenclatural novelties are proposed, the new name Pleospora tretiachii Hafellner (bas. Pleospora aquatica Tretiach & Nimis 1999 non Griffiths 1899) and the new combination Lichenochora physciicola (Ihlen & R.Sant.) Hafellner (bas. Telogalla physciicola Ihlen & R.Sant.). A key to the lichenicolous fungi occurring on Physcia species is provided.

Köckinger, H., Kučera, J., Hofmann, H., Müller, N. & Amann, G. 2012. Barbula consanguinea discovered in Switzerland and Austria, with a revision of former European records of B. indica. — Herzogia 25: 61–70.

Barbula consanguinea is newly reported from Europe based on recent records from Switzerland and Austria. B. consanguinea is well characterized among the European species of the genus by (1) clusters of small, brown and mostly clavate axillary gemmae, (2) lanceolate leaf shape, (3) not distinctly sheathing leaf base, (4) partially recurved leaf margin and (5) doubly prorate superficial cells on dorsal side of costa. Due to the similarity to Barbula indica, earlier European records of this species from Hungary, Croatia and Italy were revised. They need to be attributed to B. consanguinea, as well as the type of the recently described East Asian B. indica var. kurilensis. In Europe the species mainly occurs in early pioneer sites on moist, base-rich, more or less calcareous silt, sand and gravel in alluvia of lowland courses of streams, in particular the Rhine, Reuss, Danube, Mura and Tagliamento. The phytogeographical status of the plant in Europe — native vs. recently introduced — is discussed.

Jørgensen, P. M. & Pugh Jones, M. 2012. Leptogium resupinans new to Europe from Portugal. — Herzogia 25: 101 –102.

Leptogium resupinans has been discovered in southern Portugal. It is new to Europe and an interesting addition to the subtropical element which is present on its Atlantic coast.
