Neuwirth, G. & Aptroot, A. 2011. Recognition of four morphologically distinct species in the Graphis scripta complex in Europe. — Herzogia 24: 207–230.
Four morphologically distinct species can be distinguished in the Graphis scripta complex in Europe, namely Graphis betulina, G. macrocarpa, G. pulverulenta and G. scripta. Graphis betulina is characterized by its raised thalline margin, G. macrocarpa has open, brownish discs, G. pulverulenta has open, white-pruinose discs, and G. scripta has apothecia that remain closed. The species are recognizable in the field, but there are also microscopical differences. All species are sympatric and occasionally co-occur on the same tree.
Osyczka, P. 2011. The genus Cladonia, group Cocciferae, in Poland. — Herzogia 24: 231–249.
A revision of the genus Cladonia, group Cocciferae, is presented for Poland. The morphology, habitat and distribution of the taxa are treated, and the chemical races of each species and their frequency in the country have been indicated. The study is based on the examination of approximately 3300 herbarium specimens originating from Poland. Seventeen species have been accepted; the occurrence of the two previously reported species Cladonia bacilliformis and C. cyanipes has not been confirmed. Keys for all species known in Poland are provided.
Davydov, E. A., Himelbrant, D. E. & Stepanchikova, I. S. 2011. Contribution to the study of Umbilicariaceae (lichenized Ascomycota) in Russia. II. Kamchatka Peninsula. — Herzogia 24: 251–263.
Two species of Lasallia and 14 of Umbilicaria with one additional variety are reported from the Kamchatka Peninsula. Of these, Lasallia pennsylvanica, Umbilicaria aprina, U. cinereorufescens, U. decussata, U. hirsuta, U. hyperborean var. radicicula and U. rigida are new for the Kamchatka Peninsula. Previous reports of Umbilicaria formosana, U. leiocarpa, U. muehlenbergii, U. polyphylla, U. spodochroa and U. virginis are considered to be doubtful for Kamchatka. The lectotype of Gyrophora hyperborea f. sublaevigata Savicz was designated.

John, V., de Bruyn, U., Dolnik, C., Schumm, F., Spier, L., Stapper, N. J. & Brackel, W. v. 2011. Lichens and lichenicolous fungi of the Pfälzerwald (BLAM Meeting 2010). — Herzogia 24: 297–313.
A list of lichens and lichenicolous fungi from twelve visited sites during the BLAM-excursion in 2010 to the Pfälzerwald (Rheinland-Pfalz, Germany) is presented. The results are briefly discussed using the Red Data Book and ecological indicator values.
Bilovitz, P. O., Batič, F. & Mayrhofer, H. 2011. Epiphytic lichen mycota of the virgin forest reserve Rajhenavski Rog (Slovenia). — Herzogia 24: 315–324.
A list of 128 taxa (127 species) of lichens, 6 species of lichenicolous fungi and 2 non-lichenized fungi traditionally included in lichenological literature from the virgin forest Rajhenavski Rog and its surroundings in the southeastern part of Slovenia is presented. The lichen Gyalecta derivata, the lichenicolous fungus Homostegia piggotii, and the non-lichenized fungus Mycomicrothelia pachnea are new to Slovenia. The lichenized fungi Chaenotheca trichialis, C. xyloxena, Lecanactis abietina, Lecanora thysanophora, Pertusaria ophthalmiza, the lichenicolous fungi Monodictys epilepraria, Tremella hypogymniae, Taeniolella friesii, and the non-lichenized fungus Chaenothecopsis pusilla are new to the Dinaric phytogeographical region of Slovenia.
van den Boom, P. P. G., Brand, M., Ertz, D., Kalb, K., Magain, N., Masson, D., Schiefelbein, U., Sipman, H. J. M. & Sérusiaux, E. 2011. Discovering the lichen diversity of a remote tropical island: working list of species collected on Reunion (Mascarene archipelago, Indian Ocean). — Herzogia 24: 325–349.
463 lichen taxa are reported from the island of Reunion (Mascarene archipelago) in the Indian Ocean. This report is based on extensive collections recently made by the authors or hosted in B and LG. A total of c. 600 species is estimated for the number of lichenized fungi present on the island; although this is a low figure for a varied tropical area, this is plausible due to its small size and remoteness. The significance of the lichen diversity of the island lays in its endemics, which need further study for a reliable assessment, and in the occurrence of a poorly known southern hemisphere element (“austral” species). The discovery of the following in Reunion is of special interest as it considerably enlarges their distribution range: Anzia corallophora, Caloplaca caesiosorediata, Coccocarpia delicatula, Fuscopannaria praetermissa, Gomphillus morchelloides, G. pedersenii, Gyalideopsis bispora, Heterodermia koyana, Hypotrachyna evansii, Lithogyalideopsis zeylandica, Lobaria asperula, Megaloblastenia marginiflexa var. dimota, Menegazzia capitata, Myeloconis erumpens and Pannaria squamulosa.
Döbbeler, P. 2011. Two new hepaticolous species of the genus Octosporella (Pezizales). — Herzogia 24: 357–365.
The pezizalean genus Octosporella (Pyronemataceae, Ascomycetes) is characterized by having orange-coloured perithecia-like ascomata, thick, colourless, superficial hyphae with elaborate infection structures consisting of appressoria and intracellular haustoria, and biotrophic obligate parasitism of hepatics. Two species are described as new. Both occur on hosts not recorded before for bryophilous fungi. Octosporella epiphylla, with spherical ascospores, infects epiphyllous Lejeuneaceae (Ceratolejeunea sp.) in Costa Rica and French Guiana. Octosporella fortunata grows on terricolous Saccogyna viticulosa on the Canary Islands and forms ascomata hidden within the host mats. Octosporella currently comprises ten species.
Wirth, V. 2011. Notes on the recent distribution of Ramalina calicaris in Germany. — Herzogia 24: 367–369.
During the past decades, Ramalina calicaris was found in several areas in south-western Germany. In this region, the species was apparently continuously part of the lichen biota. The species had been correctly reported from south-western Germany until the 1950s, but was overlooked or misinterpreted afterwards. In 1999, R. calicaris was rediscovered under its correct name in the Suabian Alb.
Breuss, O. 2011. Notable records of pyrenocarpous lichens (Verrucariaceae) from Spain. — Herzogia 24: 375–378.
Seven noteworthy lichen species from Spain are listed. Placopyrenium stanfordii and Verrucaria incrassata are reported for the first time from Europe. Short notes on characteristics, ecology and distribution of the species are provided.
Etayo, J. & Sharuddin, S. S. 2011. Verruculina and Lichenoverruculina nom.nov. — Herzogia 24: 379–380.
The name Verruculina Etayo is recognized as a later homonym of Verruculina Kohlm. & Volkm.-Kohlm. As both genera are distinct, a new name, Lichenoverruculina Etayo & Sharuddin, is proposed here to replace Verruculina Etayo, and the new combination Lichenoverruculina sigmatospora (Speg.) Etayo & Sharuddin is introduced.
Matwiejuk, A. & Bohdan, A. 2011. New records of Plectocarpon lichenum from Białowieża Forest (Poland). — Herzogia 24: 381–383.
Plectocarpon lichenum is reported for the first time from the Białowieża Primeval Forest. The species has been rediscovered in Poland after more than 100 years. A list of lichenicolous fungi from Białowieża Forest is presented.
Biedermann, S. & Müller, F. 2011. New and remarkable bryophyte records from Saxony. — Herzogia 24: 385–388.
Barbula commutata, Orthotrichum alpestre, Platydictya jungermannioides, Riccia crozalsii and Schistidium lancifolium are reported for the first time from Saxony. The first confirmed records of Metzgeria fruticulosa are mentioned for Saxony. For Cephaloziella uncinata, in Saxony hitherto only known from a historical record, a recent record was found.
