Jørgensen, P. M., Schultz, M. & Guttová, A. 2013: Validation of Anema tumidulum (Lichinaceae, lichenized Ascomycota), a widespread cyanophilic lichen. — Herzogia 26: 1–7.

Anema tumidulum Henssen nom. nud. is validated by a formal description. The species is shown to be widespread in Europe. Most records come from Central Europe and Norway, but the species might still be under-collected in other regions. It is confined to calcareous habitats, sporadically moistened, sunny, open calcareous rock faces in thermophilous, mountainous situations. A list of selected examined specimens is presented. A first finding for Kazakhstan is published, whereas a published report from eastern Siberia (Russia) is shown to be based on a misidentification.

VAN DEN BOOM, P. P. G. & SIPMAN, H. J. M. 2013. Sixty-two species of lirelliform Graphidaceae (Ascomycota) new to Panama, including four species new to science. — Herzogia 26: 9–20.

Based on fieldwork in 2010 and literature study, 71 species of Graphidaceae s. str. are reported from Panama. Sixtytwo species are new to the country including three species previously known only from their types: Graphis cupei, G. pseudoserpens and G. subflexibilis. Four species are newly described: Acanthothecis salazinica, A. maritima, Graphis fissurinoides and Phaeographis boquetensis.

VONDRÁK, J. & MAYRHOFER, H. 2013. Caloplaca anularis and Caloplaca scrobiculata are distinct.— Herzogia 26: 21–29.

Caloplaca anularis, described from the Western Alps, and Caloplaca scrobiculata, described from Central Asia, are distinct species. The main differences are the shape of the thallus margin, the anatomy of the thalline cortex, characters of the algal layer and the ascospores. Caloplaca anularis is a widespread lichen known from mountain ranges in Europe (Alps, Carpathians, Balkan Peninsula), Near Asia (continental Turkey and Caucasus) and Central Asia (Altay, Karakorum, Hengduan Shan). The specimens from Central Asia differ slightly from the European specimens in thallus and medulla thickness, but we consider this difference environmentally induced and taxonomically insignificant. Caloplaca scrobiculata is restricted to arid mountain ranges of Central Asia. The Central Asian Caloplaca bohlinii does not differ significantly from C. anularis. The new combination Caloplaca anularis f. ignea is made for specimens of C. anularis with a red thallus.

Vondrák, J., Palice, Z., Mareš, J. & Kocourková, J. 2013. Two superficially similar lichen crusts, Gregorella humida and Moelleropsis nebulosa, and a description of the new lichenicolous fungus Llimoniella gregorellae. — Herzogia 26: 31–48.

Although some characters distinguishing Gregorella humida and Moelleropsis nebulosa were previously known, sterile specimens and specimens with poorly-developed apothecia are often difficult to separate. We provide morphological and anatomical characters that will allow reliable determination of such difficult collections. The most important character for determination of sterile thalli is the shape of the mycobiont cells in the thallus granules. A key summarizes the diagnostic characters of G. humida and M. nebulosa (and some similar species). The Nostoc photobiont in G. humida is morphologically similar to Nostoc from M. nebulosa but the two are not closely related within the genus. The ecology of both lichen species is similar, but there are differences in the preference for differently acidic substrates and in co-occurring bryophytes and lichens. In Central Europe, M. nebulosa was frequently collected in the first half of the 20th century, but there are few recent records, whereas G. humida was only occasionally collected before the last two decades, but is now regularly collected. Moelleropsis nebulosa rarely hosts lichenicolous fungi, though we have seen Lichenochora mediterranae (previously known only on Fuscopannaria) and Sarcopyrenia sp. on it. Gregorella humida rarely hosts a single lichenicolous fungus, described here as Llimoniella gregorellae, spec. nova, which causes obvious harm to host thalli; ITS sequences indicate that it belongs in Leotiomycetes.

OSYCZKA, P. 2013. A morphometric evaluation of the Cladonia chlorophaea group and allied taxa (Cladoniaceae, Ascomycota). — Herzogia 26: 49– 64.

The Cladonia chlorophaea group represents a complex of morphologically and chemically similar taxa that have long perplexed taxonomists. Until now, few studies have systematically evaluated morphological characters in the group. A morphometric analysis of samples belonging to the taxa of the Cladonia chlorophaea and C. humilis groups as well as C. fimbriata, was performed using various fundamental statistical methods. It revealed four unambiguously distinct morphological aggregates of samples, corresponding to four well known, cosmopolitan species, namely C. asahinae, C. chlorophaea, C. fimbriata and C. humilis. The analysis highlights the most reliable diagnostic characters distinguishing the obtained groups which can be applied for species determination. A chemical race of C. asahinae with fumarprotocetraric acid chemosyndrome only is reported from Europe and a chemotype of C. fimbriata with fumarprotocetraric and bourgeanic acids was revealed during the study. Morphometric analyses may be a very useful tool for evaluation of features within the genus Cladonia and other lichen genera containing cryptic species.

SCHIEFELBEIN, U. 2013. Additions to the lichenized and lichenicolous fungi of Mecklenburg-Western Pomerania (Germany). — Herzogia 26: 65–72.

Arthonia pruinata is rediscovered in this federal state after more than 70 years and the occurrence of Graphis pulverulenta could be confirmed.

DYMYTROVA, L., NADYEINA, O., NAUMOVYCH, A., KELLER, C. & SCHEIDEGGER, C. 2013. Primeval beech forests of Ukrainian Carpathians are sanctuaries for rare and endangered epiphytic lichens. — Herzogia 26: 73– 89.

A total of 203 epiphytic lichens and lichen-allied fungi were recorded in the Uholsko-Shyrokoluzhanskyi primeval beech forests, seven of them (Buellia chloroleuca, Lecanora strobilina, Ramonia luteola, Rinodina capensis, Thelopsis flaveola, Usnea wasmuthii and Wadeana dendrographa) are listed for the first time for Ukraine. 25 lichen species, including Arthonia vinosa, Arthopyrenia punctiformis, A. rhyponta, Bacidia incompta, Biatora carneoalbida, Buellia insignis, B. schaereri, Caloplaca cerina var. chloroleuca, C. monacensis, Megalaria laureri, Piccolia ochrophora, Porina hibernica, P. leptalea, Reichlingia leopoldii, Thelocarpon laureri, Verrucaria viridigrana, Xanthoria fulva, X. ulophyllodes are reported as new to the Carpathian Biosphere Reserve. The high species richness of rare and threatened lichens recorded in the Uholsko-Shyrokoluzhanskyi primeval forest stands underlines a high value of this area for the conservation of epiphytic lichens, i.e. an important part of forest biodiversity.

Schistidium brunnescens occurs in Thuringia in the Orla depression near Pößneck and near Saalfeld. It grouws on dolomite and calcareous slate and occurs in the basiphytic cushion bryophyte associations Grimmietum orbicularis, Orthotricho anomali-Grimmietum pulvinatae and Grimmietum tergestinae. Distribution, ecology and sociology (with 3 vegetation tables) of the associations with Schistidium brunnescens are described for Thuringia and other European territories.

HUGONNOT, V. & CELLE, J. 2013. The Leptodictyo riparii-Hygroamblystegietum varii ass. nov., a dead wood-dwelling association of near-natural alluvial forests in the Rhône valley (France). - Herzogia 26: 187–195.

The description of the Leptodictyo riparii-Hygroamblystegietum varii ass. nov. is given. It is characterized by two species, Leptodictyum riparium and Hygroamblystegium varium. This eutrophic and sciaphilic association thrives on dead wood that is alternately subject to flooding and limited periodic desiccation. It is recognized in the Rhône valley (France) but is most probably more widely distributed in western and central Europe. It is most characteristic of naturally functioning river valleys with a constant erosion of banks and redeposition of alluvial sediments in strongly dynamic soft-wooded forests.
