  The 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.
