The main phenetic features of this still poorly known species are the orange to orange-ochraceous pileus with yellowish brown margins, unchanging pileus context, the pale cream hymenophore with wide pores, the yellowish stipe, the small and narrow basidiospores, and the long and frequent dextrinoid pseudocystidioid pleurocystidia. After the discovery of the phylloporoid tube trama in our specimens, we emended tube trama type of <em>T. dunensis</em>.</p> Juliane C.

Three of them, <em>H. osseoalba</em>, <em>H. subformosana</em>, and <em>R. costaricensis</em>, are recorded for the first time for the country. The known distribution range of other eight species in the region is also extended. Distribution and comments are presented for all species, and descriptions and illustrations for most relevant records. The phylogenetic relationships of the species of <em>Hypotrachyna</em> and <em>Remototrachyna </em>reported from northeastern Argentina are analyzed.</p> Andrea Michlig Sara Moreno María Pía Rodríguez Nicolás Niveiro Viviana Solís Neffa Copyright (c) 2024 2024-01-02 2024-01-02 61 13–24 13–24 10.12697/fce.2024.61.02 Syntrichia ruralis as a suitable bioindicator for urban areas – the case study of Tallinn city <p>Environmental pollution is one of the most important problems in urban environment. Mosses are good indicators of air pollution. In Estonia, heavy metals have been measured from <em>Pleurozium schreberi</em> and <em>Hylocomium splendens</em>, which do not grow in areas of Tallinn with a higher pollution load. In the present study, Cu, Fe and Cd were measured from five moss species growing in contaminated as well less polluted areas of Tallinn. Based on stationary and street pollution source inventory and air pollution dispersion modelling, the long-term average concentrations of fine particles (PM10) and nitrogen oxides (NOx) in air were estimated. The work revealed that it is possible to find a moss species that is common in Tallinn and grows in both polluted and less polluted areas – <em>Syntrichia ruralis</em>, which is the most suitable species for bioindication based on this work. Moss species <em>Ceratodon purpureus</em> accumulated the most Cd, Cu, and Fe, then <em>Brachythecium </em><em>rutabulum</em>/<em>Sciuro-hypnum curtum</em>, and <em>Rhytidiadelphus squarrosus</em> the least. Statistically significant higher Fe concentrations were in the <em>Syntrichia ruralis</em>, compared to the <em>Sciuro-hypnum curtum</em> and <em>Rhytidiadelphus squarrosus</em>. The <em>Syntrichia ruralis </em>also had significantly higher Cd content compared to the <em>Brachythecium rutabulum</em>/<em>Sciuro-hypnum curtum</em>. The results of the GLM analysis showed that the content of various heavy metals depends on the moss species and the degree of fine particles in the environment, and it didn't depend on whether the moss grows on the soil or a hard substrate such as concrete, stone or asphalt.</p> Elle Rajandu Kadri-Liis Kaljuvee Maria Kulp Marko Kaasik Tiina Elvisto Martin Küttim Copyright (c) 2024 2024-01-02 2024-01-02 61 25–34 25–34 10.12697/fce.2024.61.03 Updates to the species list of Estonian bryophytes <p>Six species are new to the flora of Estonian bryophytes since the last additions: <em>Bryum ruderale</em>, <em>Entosthodon </em><em>fascicularis</em> and <em>Plenogemma phyllantha</em> have been found during recent fieldworks; <em>Encalypta driva</em> is a newly described species and <em>Lewinskya fastigiata </em>is a new taxonomical combination. <em>Moerckia flotoviana</em> replaces the species <em>Moerckia hibernica</em> since all herbaria specimens are re-identified. After additions and re-arrangements, the number of bryophyte species known from Estonia has risen to 618. For all new species, Estonian names are given, and they are evaluated against IUCN criteria. Two of the species were included in category DD, because of shortage of data; <em>Lewinskya fastigiata</em> was evaluated as LC, and <em>Encalypta driva</em> and <em>Plenogemma phyllantha</em> as VU. The IUCN category of <em>Moerckia flotoviana </em>remained as it was for <em>Moerckia </em><em>hibernica</em> (LC).</p> Tiiu Kupper Kai Vellak Loore Ehrlich Leiti Kannukene Mare Leis Nele Ingerpuu Copyright (c) 2024 2024-01-02 2024-01-02 61 35–38 35–38 10.12697/fce.2024.61.04
