Sphaerocarpos michelii, a new liverwort species in Hungary
19-25Views:171Until 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.

Bruchia flexuosa (Schwägr.) Müll. Hal. a true peculiarity in the Hungarian bryoflora
193-201Views:105The fifth European occurrence of the moss species Bruchia flexuosa possessing a holarctic distribution range with a North American centre was encountered in Hungary. Outside of the North American continent only two Asian (both from Japan) and four European occurrences from four different countries (Italy, Austria, Slovenia, Croatia) have hitherto been reported. Apart from the recent Japan findings and the Croatian record observed in 1987, all other European records date back to the 19th century. Our paper reports the circumstances of the Hungarian occurrence along with a short descriptions and photographic illustrations of both the species and its habitat.

A new montane bryophyte species from the Mátra Mts, Hungary: Hymenoloma crispulum
11-18Views:193Due to the geomorphological situation and climatic conditions of Hungary, true montane climate is restricted to very few and small areas of higher elevation, with the highest peak (Mt Kékes, 1014 m) in the Mátra Mountains (North Central Hungary). During a bryofloristical survey in this region, a few cushions of a Boreo-arctic montane bryophyte species, Hymenoloma crispulum (Hedw.) Ochyra (syn.: Dicranoweisia crispula (Hedw.) Milde), was discovered at the steep northern slope of Mt. Kékes in an andesite boulder scree with cool and humid microclimate. H. crispulum is new to the Hungarian bryoflora and fits in well with other co-occurring vascular and cryptogamic taxa of northern-montane affinities. The population is very small and vulnerable, therefore it should be rated 'critically endangered' (CR) in an updated national red list.

Distribution of Pseudoleskea saviana (De Not.) Latzel in Hungary
272–285Views:123Three new localities of the moss species Pseudoleskea saviana (De Not.) Latzel were discovered in the Börzsöny Mts in the administrative district of Perőcsény village, North Hungarian Mountains (Nagy-Hideg-hegy, near Hangyás-bérc, in the col between Csóványos and Magosfa). Small populations were found on shaded andesitic boulders in mixed deciduous forests. Up to the present, only old collections of the species were known from a single locality in the Mátra Mts; therefore, the red list status was data deficient. The morphological distinction of P. saviana from P. incurvata, its closely related congener also reported from Hungary is not always exempt from difficulties. However, the presence (P. saviana) or absence (P. incurvata) of a central strand in the stems, the shape of mid-leaf cells (P. saviana: more elongated, 3–4 times as long as wide; P. incurvata: at most twice as long as wide), as well as the shape of the outer basal cells (P. saviana: quadrate or shortly rectangular; P. incurvata: transversely elongated) seem to be reliable distinctive features.

New montane species in the Hungarian bryophyte flora
16-26Views:635During a bryofloristical investigation in the vicinity of Ómassa (Miskolc) in the Bükk Mountains (NE Hungary), three montane-boreal bryophyte species new to the Hungarian bryoflora were collected. Encalypta spathulata Müll.Hal. was found on the ledges of limestone cliffs of Vörös-kő Hill as well as on the rocky debris among roots of a fallen tree lying under the cliffs. Hydrogonium croceum (Brid.) Jan Kučera and Orthothecium rufescens (Dicks. ex Brid.) Schimp. were found in the crevices of dolomite cliffs on the north-facing steep slope of Jávor Hill. While the latter two species are widespread in European Mountains, E. spathulata is considered to be a rare species, and is assessed as ‘Vulnerable’ in the IUCN red list.

Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora
173–184Views:163The paper deals with the species found during cryptogamic flora mapping in 2023 that are remarkable from a floristic, taxonomic or conservational point of view. We present data from the Bükk Mts of two Trapeliopsis species which appear to be rare in Hungary. Multiclavula mucida, which is apparently a rare basidiomycete lichen species in Europe that prefers humid, montane habitats was discovered in the Mecsek Mts as a new species for the Hungarian flora. Of the knothole moss, Anacamptodon splachnoides, which is now thought to be entomophilic, we communicate the only extant population from Southern Transdanubia. We report the first occurrence of the atlantic-mediterranean Leptodon smithii from the Hungarian side of the Great Hungarian Plain. Numerous data of the corticole Neckera pennata indicate that in Hungary the distributional centre of this species is situated in the county of Baranya in the lowlands. New data from the Bükk Mts underline that in the Pannonian region Buxbaumia viridis is primarily a terricole species of acidophilous beech forests. We communicate the first occurrence from the lowlands of the alien lignicolous Sematophyllum adnatum which is dangerously spreading in Europe, at the same time one of the most vigorous populations in the Pannonian region. The third Hungarian occurrence of Callicladium haldanianum, a species that seems to spread in bogs, as well as the second occurrence of Racomitrium lanuginosum, growing abundantly on an andesite boulder scree in Mátra Mts, are also reported here. Of Phegopteris connectilis we present in photographic documentation the first extant population from Southern Transdanubia, and we discuss whether the first publication from Mecsek Mts is correct or exact. In addition to listing the floristic data, we also briefly discuss the (mis)use of distribution data in the context of climate change, the difficulties of distinguishing the microtaxa of some pteridophytes, e.g. Asplenium adiantum-nigrum agg. and Dryopteris affinis agg., and we correct one of our previously published, erroneous Hedwigia stellata data. Some interesting data of other taxa (such as Leucobryum glaucum, Palustriella commutata, Tetraphis pellucida, Gymnocarpium robertianum, Ophioglossum vulgatum) are also mentioned in the paper.

Campylopus flexuosus (Hedw.) Brid.: a moss new to the Hungarian bryophyte flora
22-28Views:91Two localities of Campylopus flexuosus new to Hungary were discovered by the authors near Uzsa in the Bakony Mts during mapping of the Hungarian bryoflora. In this paper the circumstances of the occurrences are described and illustrated by maps and photographs; a short description of the species is provided together with photographs of diagnostic characters.
