  Until now, the genus Sphaerocarpos, which can be recognized at first glance due to its characteristic appearance, was represented in Hungary by S. europaeus only, for which a single old record exists. In January 2022 the other widely distributed European congener, S. michelii Bellardi, was discovered on an arable field of lucerne in Somogy county. We report the habitat characteristics of the single known population of S. michelii in Hungary, describe the morphology of the species and deal with the differentiation of the two Sphaerocarpos species. In order to facilitate species identification, we include light and electron micrographs showing essential details of the spore surface of S. michelii.

  In this study we present the current moss and liverwort flora of the Arboretum of Szarvas. The observations were made in 2017, 2019, 2020 and 2021. Altogether 95 bryophyte taxa (7 liverworts and 88 mosses) were identified. Most of them are considered to be common in Hungary, however some species are rare in the Great Hungarian Plain: Lophocolea coadunata, Climacium dendroides, Hylocomiadelphus triquetrus, Pleurozium schreberi, Polytrichum formosum, Rhytidiadelphus squarrosus, Ulota crispula, Zygodon rupestris. These results also confirm the conservational and scientific value of the arboretum.

  This paper presents the results of the first bryofloristic survey in kurgans from North East Hungary. Altogether 41 taxa (1 liverwort and 40 mosses) were recorded from nine burial mounds. The most frequent mosses were Brachythecium rutabulum, Tortula acaulon var. acaulon and Barbula unguiculata from the localities. I found several infrequent bryophyte species on the surveyed Hungarian kurgans, such as Acaulon muticum, Acaulon triquetrum, Pterygoneurum subsessile, Riccia ciliata, Tortula caucasica, Trichostomum brachydontium and Trichostomum crispulum. There was no correlation between the number of bryophytes and the area of the kurgans. The proportion of the annual shuttle life strategy, i.e. species with a very short life span, is relatively high compared to other recent studies from Hungary (e.g. Buda arboretum and Balaton village), thereby these habitats may be potential refuges for ephemeral bryophytes.

  This is the first bryofloristic study in the Martonvásár manor park. In our survey in 2015, 56 species (6 liverworts and 50 mosses) were found in the park. Most of them are considered to be common in Hungary, but an endangered (Eurhynchium speciosum), a vulnerable (Orthotrichum patens) and five near-threatened species (Aphanorrhegma patens, Orthotrichum obtusifolium, Orthotrichum pumilum, Pseudocrossidium revolutum, Riccia cavernosa) were also found. These results point out the nature conservation value of the manor park.
