Baumann, M., Dittrich, S. & Oheimb, G. v. 2019. Effects of periodic liming on the bryophyte layer in Norway spruce (Picea abies) stands in the Erzgebirge (Ore Mountains). – Herzogia 32: 269–287.
Severe changes in forest soil conditions, tree health and growth as well as plant species composition have been observed as a consequence of atmospheric acid deposition. The most important measure to counteract soil acidification is forest liming. The long-term effects of repeated liming on the bryophyte layer of forests, however, have rarely been analysed. We used a stratified design to sample the bryophyte layer of spruce stands located in the Erzgebirge (Ore Mountains, eastern Germany). Study sites were unlimed or limed at different intensities between one and five times since 1988. We found a significant effect of liming intensity on the composition and diversity of the bryophyte layer. The liming gradient is reflected by numerous indicator species, by indicator values for pH and nitrogen, and the by alpha and beta diversity of the species present. Liming strongly reduces the cover of many acidophytes typical for the habitat. By contrast, indicator species of disturbance and some rare, nutrient-demanding species appear to benefit from liming. These effects increase with liming intensity. Our results suggest that larger liming exclusion zones should be created to protect the typical bryophyte species composition.
Gey, S. 2019. New records and remarkable rediscoveries of bryophytes in southeastern Bavaria. – Herzogia 32: 288 –314
New to the German Alps is Warnstorfia pseudostraminea. The species Andreaea rupestris, Barbilophozia hatcheri, Bartramia ithyphylla, Grimmia alpestris, Odontoschisma elongatum, Scapania paludicola and Splachnum sphaericum are new to the Chiemgau Alps. Remarkable rediscoveries are Cinclidotus aquaticus, Cyrtomnium hymenophylloides and Sarmentypnum sarmentosum. Remarkable records for the Alpine foothills are Anacamptodon splachnoides, Bartramia pomiformis, Buxbaumia aphylla, Diphyscium foliosum, Notothylas orbicularis, Riccia fluitans and Sphaerocarpos texanus. For the species Buxbaumia viridis a list of numerous new records is presented.
Rimac, A., Šegota, V., Alegro, A., Koletić, N., Vuković, N. & Papp, B. 2019. New and noteworthy bryophyte records from lacustrine drawdown zones in Croatia. – Herzogia 32: 315 –325.
Ephemeral bryophytes are short-lived species that can germinate and finish their whole life cycle within a brief period when favourable conditions occur. A significant number of these specialist species are associated with moist and fine-textured substrata of the margins of lakes, reservoirs and rivers, also known as drawdown zones. Our study of the vegetation of drawdown zones, the first focusing on these specific habitats in Croatia, resulted in significant records for Croatian bryoflora; a new species (Physcomitrium eurystomum), confirmation of two species, the occurrence of which was doubtful (Riccia cavernosa and R. frostii) and new localities of two extremely rare species (Physcomitrella patens and Leptobryum pyriforme). Although these species and their habitats are considered relatively rare and threatened in Europe, the low number of records in Croatia is to a considerable extent the result of there having been insufficient research into ephemeral habitats and the bryophyte flora in general.
Bednarek-Ochyra, H. & Plášek, V. 2019. Entosthodon productus (Bryophyta, Funariaceae), an addition to the moss flora of the subantarctic Îles Crozet. - Herzogia 32: 326 -337.
Entosthodon productus, an Australasian species, is recorded for the second time from the Subantarctic. In contrast to Marion Island in the Prince Edward Islands archipelago where the species is relatively frequent, only a single specimen of E. productus was found on Île de la Possession in the conterminous Îles Crozet archipelago. The island's plants are characterised and illustrated and the geographical distribution of E. productus is reviewed. The present diversity of the moss flora of Îles Crozet is briefly summarised.
Cano, M. J. 2019. New data on the moss genus Stegonia (Bryophyta, Pottiaceae). – Herzogia 32: 338 –343.
Stegonia hyalinotricha is recorded for the first time from South America. The species, until now known only from Mexico and the U.S.A. (California), was collected in the Monte Desert of Chubut (Argentina). The species is briefly characterized and illustrated. Stegonia mouretti, endemic from Morocco, is placed in synonymy with Pterygoneurum ovatum and the name lectotypified.
Cao, W., Xiong, Y.-X., Zhao, D.-G., Qu, J.-J. & Tan, H.-Y. 2019. Porella perrottetiana var. angustifolia (Porellaceae, Marchantiophyta), new to China, and taxonomic revision of Porella perrottetiana in the East Yunnan-Guizhou Plateau. – Herzogia 32: 344 –356.
Porella perrottetiana var. angustifolia (Porellaceae, Marchantiophyta), a neglected variety known from North Vietnam, is reported here as a new addition to the Chinese liverwort flora from east of the Yunnan-Guizhou Plateau, SW China. It is characterized and distinguished from known Chinese species of Porella by attenuately ligulate or lanceolate and falcate leaf lobes with a long terminal and 0 – 4(–5) lateral ciliate teeth, median cells significantly larger than marginal cells, and by forming vitta from base to apex of leaf lobes. Detailed illustrations and description of this variety, an identification key to three varieties of Porella perrottetiana as well as a taxonomic revision of Porella perrottetiana in east of the Yunnan-Guizhou Plateau are provided.
Ochyra, R. & Plášek, V. 2019. On the taxonomic status of Isopterygium ambiguum (Hypnaceae, Bryophyta) from Gough Island in the South Atlantic Ocean. - Herzogia 32: 357-368.
The original material of Isopterygium ambiguum, a species known only from the type collection from Gough Island in the South Atlantic Ocean, is taxonomically assessed and some details of its morphology are illustrated. The species is conspecific with the Afro-American I. tenerifolium. The global distribution of I. tenerifolium is reviewed and mapped and the locality on Gough Island represents its southernmost known occurrence. In addition, the species is known from several collections from Tristan da Cunha and Nightingale Island. The distribution patterns of the South Atlantic mosses are briefly discussed.
Tang, Q.-M., Ho, B.-C. & Wei, Y.-M. 2019. An IUCN threatened moss species, Hypnodontopsis apiculata (Rhachitheciaceae, Bryophyta), new to China. – Herzogia 32: 369 –374.
A threatened species Hypnodontopsis apiculata, previously known only from Japan, is reported here as a genus and species record new to the bryoflora of China. Based on the present gathering, a detailed description and photographs are provided. Considering the fragile habitats of H. apiculata, we propose here to maintain its current conservation status as Vulnerable.
Tsurykau, A., Bely, P., Golubkov, V., Persson, P.-E. & Thell, A. 2019: The lichen genus Parmelia (Parmeliaceae, Ascomycota) in Belarus. Herzogia 32: 375 –384.
Four hundred eighty-three specimens of the genus Parmelia collected in Belarus were examined. Four species, P. ernstiae, P. saxatilis, P. serrana and P. sulcata, were identified in this study. The distribution of these species in Belarus is reviewed. Parmelia saxatilis appeared to be an extremely rare species in Belarus known from a single locality. Parmelia ernstiae is reported from Belarus for the first time. The presence of Parmelia fraudans and P. submontana has not been confirmed, and they are therefore excluded from the Belarusian list of lichen species. Morphological and chemical characters of the isidiate and corticolous species Parmelia ernstiae and P. serrana are briefly discussed.
Pyrcha, M. & Oset, M. 2019. Saxicolous species of the genus Pertusaria s.l. in Poland. – Herzogia 32: 385 –397.
Notes on the morphology, secondary chemistry, habitat requirements and distribution of saxicolous species belonging to the genus Pertusaria s.l. in Poland are provided. The following species are treated: Lepra aspergilla, L. corallina, L. ocellata, L. schaereri, Pertusaria flavicans, P. melanochlora, P. pseudocorallina and Varicellaria lactea. Although most of these species are reported from the southern part of the country, a key to all species known from Poland is provided. A chemotype of P. melanochlora lacking picrolichenic acid is reported for the first time. Pertusaria chiodectonoides and P. inopinata are considered uncertain records from Poland due to the lack of available material. The identity of P. eitneriana described from Poland is unclear; it was recorded only by the type collection.
Kubiak, D. & Osyczka, P. 2019. Tree avenues as reservoir for epiphytic lichens in deforested landscapes. – Herzogia 32: 398 – 420.
Old tree avenues are a disappearing traditional element in European landscapes. Roadside trees constitute an important habitat for many groups of organisms and support the maintenance of biodiversity in deforested areas, but they are often neglected in conservation strategies. This study describes and analyses the conservation value of planted trees along rural roads in NE Poland for epiphytic lichens. A total of 105 trunks of seven deciduous tree species were examined. Lichen species inventories were assembled for trunks at a height up to two meters from the ground. A total of 99 lichen species was recorded. Lichen species richness and cover were dependent primarily on tree species. Diameter of trees was not significantly correlated with the number of species. Ulmus laevis and, to a lesser extent, Fraxinus excelsior and Acer platanoides, were be the most valuable tree species in terms of lichen species richness. Quercus robur as a roadside tree did not have above-average species numbers. Lichen species with a preference for eutrophicated or alkaline bark occurred in their largest numbers on Populus nigra agg. Betula pendula hosted the largest number of species avoiding eutrophication. Each tree species had its own set of exclusive lichens and hosted taxa which are red-listed in Poland; however, no single tree species alone guarantees preservation of the entire range of epiphytic lichens on roadside trees in the study area. Since tree avenues, especially those composed of multiple species, provide a suitable habitat for various rare and endangered lichens, potentially high conservation value should always be attributed to this element of local landscapes in low pollution areas.
van den Boom P.P.G. & Alvarado P. 2019. Lichens and lichenicolous fungi of Faial (Azores, Portugal) with descriptions of three new species. - Herzogia 32: 421– 437.
Results of a fieldtrip to Faial in 2016 are treated on lichens and lichenicolous fungi. Of the 109 taxa recorded, 14 are new to the Azores, and one new genus (Cliomegalaria) and three new species, Bacidia sigmospora, Bacidina terricola, Cliomegalaria symmictoides, are proposed to accommodate specimens not matching any known taxon.
Shivarov, V. V. 2019. Clypeococcum hemiamyloideum (Polycoccaceae, Ascomycota), a novel lichenicolous fungus on Verrucaria latebrosa. - Herzogia 32: 438–443.
Clypeococcum hemiamyloideum is described as a novel lichenicolous fungus on Verrucaria latebrosa from the Malyovitsa River, Bulgaria. It is characterized by two types of hymenial gels: lower gel predominant, hemiamyloid (1+ red), upper gel only in the ostiolar region, euamyloid (1+ blue), a variable spore number in the mature asci (1–8), pseudothecia 100–175 µm diam., black, and ascospores 17.8–20.3 x 6.6–7.6 µm, brown, thick-walled, warted, 1-sep-tate. The reactions of the hymenial gels in C. hemiamyloideum and V. latebrosa were tested with different concentrations of IKI in order to identify their types and thresholds.
Brackel, W. v. & Berger, F. 2019. Lichenicolous fungi from Sardinia (Italy): new records and a first synopsis. - Herzogia 32: 444 - 471.
During a four week excursion of the first author to Sardinia in 2014, 64 sites of lichenological interest were visited. The second author visited 12 sites in a one week excursion in 2011. The results of these field studies are presented here with special emphasis on lichenicolous fungi, completed with data from the literature to produce a first checklist for the island. The list comprises 42 species known only from the literature and 167 species including the authors' recent finds. Among them one species, Sporidesmiella lichenophila U.Braun & Heuchert, is new to Europe, 15 species are new to Italy and 87 species are new to Sardinia. In addition the finds of 13 lichenicolous lichens are mentioned. The new species Endococcus sardous Brackel is described. One new combination is proposed, Polycoccum minus (Kernst.) Brackel comb. nov. (= Microthelia minor Kernst.), as we were able to find a specimen of this rare species.
Davydov E. A., Chesnokov S. V., Konoreva L. A. & Andreev M. P. 2019. Umbilicariaceae (lichenized Ascomycota) from the Stanovoye Nagor’e Highlands (South Siberia, Russia). – Herzogia 32: 472– 484.
Twenty species of Umbilicariaceae are reported from the Stanovoye Nagor’e Highlands, mostly from the Kodar Range. Of these, Umbilicaria rhizinata is new for Russia, U. formosana and U. kisovana are new for Siberia, U. herrei is new for South Siberia, U. lyngei and Xylopsora friesii are new for the Stanovoye Nagor’e Highlands. The distribution patterns of the studied species are discussed. Previous reports of Umbilicaria (Lasallia) papulosa from Siberia are considered to be doubtful.
Hellou, S., Uriac, Ph., Le Dévehat, F., Sauvager, A., Jéhan, Ph., Zebboudj, A., Boustie, J. & Esnault, J. 2019. A chemotaxonomic study of the Xanthoparmelia pulla group in Algeria. – Herzogia 32: 485 –502.
The Xanthoparmelia pulla group is well represented in Algeria from coastal to desert areas. As it is difficult to recognize the species without chemical data, we undertook a study of specimens collected in Algeria using chromatography (TLC and HPLC), mass spectrometry and fluorimetry. Our results confirm the presence of six species, two of which are represented by two chemotypes. We report two diphenyl ethers (β-collatolic and β-alectoronic acids) for the first time in X. glabrans. We also provide a key to these taxa based on chemical data, and employ a new test combining UV and K reactions.
