Dudáš M., Eliáš P. jun. & Mártonfi P. (2016): Occurrence of Taraxacum serotinum (Waldst. et Kit.) Fisch. (sect. Dioszegia) in Slovakia. – Thaiszia – J. Bot. 26 (1): 1-10. – ISSN 1210-0420.
Abstract: Historical and recent occurrence of a rare dandelion Taraxacum serotinum (Waldst. et Kit.) Fisch. in the area of Slovakia was studied. Herbarium specimens deposited in 16 herbaria were revised and field research during 2009–2015 was carried. In total, 76 localities were recorded, but only 16 sites have been confirmed or newly found at the present. Taraxacum serotinum is recently considered as an endangered species (EN) of the Slovak flora. Distribution map of the historical and recent locations of the species is given.
Keywords: Taraxacum serotinum, endangered species, distribution, Slovakia.

Abstract: The genus Erodium (Geraniaceae) composed of 75 species in all continents except Antarctica. Its main center of diversification is Mediterranean region with 62 species. There are 15 annual and perennial Erodium species in Iran. In present study stem, leaf and petiole anatomical structures were considered for 16 populations of 7 Erodium species. Totally 18 qualitative and 27 quantitative features were evaluated and measured. Anatomical data revealed a significant variation between studied species. The most diagnostic characters were shape of abaxial leaf cross sections and form of gaps, diameter of stem cross section, presence or absence of fiber in petiole structure, number and shape of vascular bundles in stem, stem hair type, shape of adaxial surface of midrib and number of vascular bundles in petiole. Studied taxa were clearly separated by selected anatomical characters.
Keywords: anatomical structure, Erodium, Geranicaceae, leaf, stem, petiole.

Jančovičová S., Senko D. & Kučera V. (2016): What do we know about the Callistosporium collections from Slovakia? – Thaiszia – J. Bot. 26 (1): 27-40. – ISSN 1210-0420.
Abstract: In Slovakia, two species of the genus Callistosporium are known, C. luteo-olivaceum and C. pinicola, both only with low number of collections and a brief description of macroscopic and microscopic characters. In this paper, information about all Callistosporium collections from Slovakia is gathered and data on species ecology, distribution and threat within Europe summarized. Callistosporium luteo-olivaceum is also provided with a detailed description based on the own collection.
Keywords: fungi, Agaricomycotina, rare species, morphology, ecology, distribution range.

Abstract: We studied historical and recent occurrence of halophilous dandelion Taraxacum bessarabicum (Hornem.) Hand.- Mazz. in Slovakia. Herbarium specimens from 16 public herbaria were revised and field research during 2010–2015 was carried out. In total, circa 60 localities were recorded, 29 sites are documented by herbarium vouchers and 31 sites were excerpted only from the literature and unpublished data. Only five locations were confirmed recently, therefore we suggest keep the listing of the species on the IUCN category EN (endangered). Concerning the phytosociological approach, four recent locations of T. bessarabicum were found in saline vegetation of the alliance Puccinellion limosae, whereas its past frequent occurrence in the alliance Juncion gerardii was failed to confirm. Synanthropic occurrence was observed in Košice along gravel roadsides, between panels and on the edges of parking places and footpaths in stands close to vegetation of alliance Dauco-Melilotion. Distribution map of the historical and recent distribution of the species is given.
Keywords: Taraxacum bessarabicum, habitats, coenology, distribution, Slovakia.

Abstract: We present new phytosociological and chorological data of five rare and endangered plant species of Slovakia: Chlorocyperus glomeratus, Dichostylis micheliana, Lindernia procumbens, Heleochloa alopecuroides and Scirpus radicans. All of them are characteristic species of periodical wetland habitats. We observed them in 2015, when optimal wheather circumstances (humid early-vegetation period followed by very dry and warm summer) were present. As they were recorded in new locations within the Podunajská and Východoslovenská nížina lowlands, brief characteristics of the new sites are provided as well. We also point out the negative trend of eutrophication in the natural mudflat vegetation in Slovakia.
