The Eocene-Oligocene Transition is one of the major stages of the Cenozoic reshaping of the world oceans with associated changes in climate, of ocean coastlines and circulation patterns. This altogether created challenging environments for fossilization and preservation of native biota. Consequently, well preserved Oligocene fossils are infrequent worldwide and just as rare in the Central Paratethys. The well-preserved Rupelian (Early Oligocene) diatomites from the Skole Nappe, the external unit of the Outer Carpathians in southeastern Poland were deposited in the Central Paratethys. In some samples, in addition to diatoms, sediments also contain a great diversity of other silicified micro- and nannofossils. Here we report our findings of silicoflagellates (fifteen taxa from five genera), two rotosphaeridians, and several morphotypes of fossil scales, some of uncertain taxonomic affinity. Among silicoflagellates, the most common are species from genera Corbisema (C. triacantha, C. hastata, and C. apiculata) and Dictyocha (D. clinata and D. fibula). We also recovered scales of rotosphaeridians (Pinaciophora and possibly Rabdiophrys) and remains of organisms of uncertain affinity (Clathropyxidella and Macrora) often reported together with silicoflagellates. All of these taxa are the first reports for the Central Paratethys. Silicoflagellate species composition is consistent with the datums derived from other fossils. Silicoflagellates, marine diatoms and archaeomonads suggest a neritic depositional environment.

The presence of autotrophs, heterotrophs and mixotrophs among euglenoid taxa, multiple means of nutrition, and high tolerance to a wide range of thermal living conditions contribute to their colonization of various types of water bodies in different climatic zones. The formation of water “blooms” by euglenoids occurs during accelerated development and intensive cell division of these organisms. Euglenoids outcompete other microalgae and produce significant biomass under favorable conditions. The ability to produce temporal, reproductive and protective cysts also contributes to rapid bloom formations. Our observations suggest that their features probably make them model organisms for observing environmental changes in small water bodies. So far, little attention has been given to the species-dependent color variation of euglenoid blooms. Long-time research on euglenoid taxonomy, biogeography and habitat observations allow observers to recognize different blooms depending on the species causing the phenomenon: Euglena sanguinea, E. mutabilis, E. clara, E. hemichromata, E. geniculata, E. agilis, Euglenaria anabaena, Euglenaformis chlorophoenica, Monomorphina pyrum, Phacus pleuronectes, Ph. orbicularis, Lepocinclis ovum, Trachelomonas volvocina, T. volvocinopsis and T. caudata. The color range of euglenoid blooms are presented here for the first time.

Within the lichen family Teloschistaceae, a high number of genera are restricted to the extreme southern part of the Southern Hemisphere. The taxonomy and phylogeny of the southern genus Gondwania have been analyzed based upon fieldwork in Antarctica, Patagonia, New Zealand and Tasmania and subsequent studies including molecular methods. Five species are accepted in the genus Gondwanea including G. inclinans and G. joannae that are combined into the genus. Two species are included in the neighboring new genus Transdrakea, T. alacalufes, a saxicolous species from Patagonia, which is described as new to science and T. schofieldii. Based on molecular data, Austroplaca imperialis is described as a new species to accommodate Patagonian specimens previously named G. regalis. Even though morphologically very similar, the two species are distinct based on molecular and chemical characters and distribution. Gondwania and Transdrakea are chemically homogenous with parietin as the very dominant compound; Transdrakea has a very reduced thallus, whereas Gondwania includes species with crustose thalli, as well as species with fruticulose growth habits. G. inclinans and G. cribrosa are only known from Australia/New Zealand. G. regalis, G. joannae and T. schofieldii are only known from Antarctica. G. sublobulata is confirmed from Patagonia and the Falkland Islands, but Antarctic specimens previously named G. sublobulata belong to G. joannae. G. sejongensis is shown to be a synonym to G. joannae. A key to Gondwania and Transdrakea species is presented.
在地衣科（Teloschistaceae）地衣属中，有很多属只分布在南半球的最南端。根据在南极洲、巴塔哥尼亚、新西兰和塔斯马尼亚进行的实地考察以及随后进行的包括分子方法在内的研究，我们分析了南部冈瓦纳属（Gondwania）的分类和系统发育。Gondwanea 属中有五个物种被接受，其中包括 G. inclinans 和 G. joannae，它们被合并到该属中。两个物种被归入邻近的新属 Transdrakea，即 T. alacalufes（一种产自巴塔哥尼亚的穴居物种）和 T. schofieldii。根据分子数据，Austroplaca imperialis 被描述为一个新物种，以适应以前被命名为 G. regalis 的巴塔哥尼亚标本。尽管在形态上非常相似，但根据分子和化学特征以及分布，这两个物种是不同的。Gondwania 和 Transdrakea 的化学成分相同，叶绿素是最主要的化合物；Transdrakea 的菌柄非常细小，而 Gondwania 包括具有壳质菌柄的物种，以及具有纤毛生长习性的物种。G. inclinans 和 G. cribrosa 只产于澳大利亚/新西兰。G. regalis、G. joannae 和 T. schofieldii 只产于南极洲。sublobulata 证实产自巴塔哥尼亚和福克兰群岛，但之前命名为 G. sublobulata 的南极标本属于 G. joannae。joannae 的异名。Gondwania 和 Transdrakea 物种的检索表。

The genus Coenogonium, the only genus in the family Coenogoniaceae, is mostly found in tropical and subtropical regions. Approximately 100 species of Coenogonium are known worldwide, and about 52 species have been previously recorded from Brazil. Here, we describe four species as new to science from the Atlantic Forest in the states of Bahia, Minas Gerais, and Sergipe, and present a few new state records. The new species are C. carassense, C. itabaianense, C. pilosum, and C. subtomentosum. An annotated checklist of the species of Coenogonium from Brazil is also included.

National parks and other federally designated natural areas play critical roles in preserving unique habitats, communities, and biodiversity. However, in the United States, it is estimated that 80–90% of species diversity in national parks is presently unknown. Therefore, contemporary biodiversity inventories are critical for conservation, management and establishing baselines for future comparisons. Ongoing efforts to characterize lichen diversity highlight diverse and robust communities in a number of national parks in the USA. In arid regions of the western USA facing ecological transformations, lichens can play a pivotal role for monitoring these changes. Lichen diversity in Bryce Canyon National Park (BRCA) in southern Utah, USA remains nearly completely uncharacterized, despite nearly 100 years as a federally protected area. Our study aims to provide a critical perspective into the lichen diversity of BRCA. Using a metabarcoding community sampling approach, we documented 215 candidate lichen-forming fungal species distributed across ecologically distinct sites in BRCA. At each sampled site, species richness ranged from 104 to 133 species, with no more than 20% shared species among the three sites. The limited overlap between collection sites suggests that BRCA harbors greater diversity than initially thought. We document a number of sensitive lichens, particularly Usnea spp. and Ramalina sinensis, that should be monitored as air pollution, land use, and impacts of climate change affect biological communities in the park. The inventory also includes unknown species and other species that have not been documented in the western USA. While our DNA-based inventory highlights strikingly rich lichen diversity, future voucher-based collections will be essential for robust taxonomic determinations.

Type material of twelve species of Usnea related to Asia and South Africa were studied and one species from North America is newly described. Holotype specimens of eight Chinese taxa described in 1975 were synonymized as follows: U. mengyangensis is lectotypified and synonymized with U. aciculifera. Usnea recurvata and U. subrectangulata are synonymized with U. baileyi. Usnea kirinensis is synonymized with U. barbata s.str. Usnea crassiuscula and U. yunnanensis (= U. australis J.D. Zhao et al., nom. illeg. non Fr.) are synonymized with U. bismolliuscula. Usnea iteratocarpa is synonymized with U. cristatula (new to Asia, China). Usnea decumbens is synonymized with U. intumescens (new to Asia, China). Usnea entoviolata and U. roseola are synonymized with U. fragilis (new to Asia, China, India, Japan). The lectotype of Usnea trichoideoides was found to belong to the Usnea pectinata aggr. and consequently U. montis-fuji was resurrected for U. trichodeoides sensu Ohmura. Usnea ceratina and U. trichodeoides are excluded from the Japan lichen flora. Usnea macaronesica a recently described Macaronesian and South American species is synonymized with the Asian taxa U. pycnoclada. Usnea chicitae is described as a new species endemic of the Southern Appalachian Mountains. It is characterized by stipitate efflorescent soralia, a tenuicorticata-type of CMA and the presence of salazinic and psoromic acid in the medulla.

The type species of the lichen genus Variolaria is V. discoidea. The name is solely based on a Hoffmann (1784) illustration. To stabilize the nomenclature, we have designated a lectotype and an epitype from Germany, for which we generated molecular data. The species was formerly placed in the genus Pertusaria as P. albescens, and is presently correctly named Lepra albescens.

Agonimia gargominyi (Verrucariaceae, Verrucariales) is described and illustrated from bark samples collected from Morane atoll (Tuāmotu-Gambier Islands, French Polynesia). It is characterized by the large superficial perithecia having a pale brown-colored ostiolar region, the 8-spored asci, and the relatively large lobed squamules. Micromorphology of the ascomata and the thalline squamules matches the genus Agonimia. Additionally, to accommodate the inclusion of this newly identified species, the existing comprehensive key encompassing all known Agonimia species worldwide has been modified and updated accordingly. Detailed illustrations supplement the description of Agonimia gargominyi.

The new combination Thalloidima squamatum is proposed for a morphologically and phylogenetically distinct species, until now included within the variation of T. sedifolium. Compared to T. sedifolium, the species is characterized by its larger squamules and apothecia, shorter ascospores, the pale color of the excipulum, and its habitat growing on moss cushions over calcareous rock or directly on rock rather than on soil. Most of the material studied originates from Norway and Sweden, but specimens are also reported from Austria, Croatia, Germany, Greenland, Italy, Poland, Russia, Scotland and Switzerland.
新的组合Thalloidima squamatum是为一个形态上和系统发育上独特的物种而提出的，直到现在该物种还被归入T. sedifolium的变种中。与 T. sedifolium 相比，该物种的特点是鳞片和皮孔较大，无托叶较短，外生孢子颜色较浅，栖息地生长在石灰质岩石上的苔藓垫上或直接生长在岩石上而非土壤中。研究的大部分材料来自挪威和瑞典，但也有来自奥地利、克罗地亚、德国、格陵兰岛、意大利、波兰、俄罗斯、苏格兰和瑞士的标本报道。
