Cryptogams, often neglected in vegetation dynamics studies, compose a large part of biomass and contribute to the biodiversity of sandy grasslands. Since the work of Verseghy (1970s), their productivity has not been analyzed in Hungary. We studied the lichen and bryophyte dynamics (hereinafter called cryptogams) at two Eastern Hungarian dry sandy grassland sites. The sites of Corynephorus canescens and of Festuca vaginata dominance, respectively, belonging to the community Festuco vaginatae–Corynephoretum have been monitored. We aimed at (1) quantifying the diversity and biomass of the cryptogamic communities; (2) exploring the cryptogamic response to management changes; and (3) studying the effect of experimental management (fencing) on the cryptogamic assemblages. The sites have been compared in 2013 and 2018, respectively. Forty microplots per site per management have been analyzed in both years. Samples of lichens and bryophytes were hand-sorted, dried and then measured. Fencing has led to increased biomass of cryptogams within a few years. Lichens in general benefited comparatively more from exclosure than bryophytes. The increase in lichen biomass (especially that of Cladonia rangiformis) is clearly due to the over 10-year absence of grazing. The only lichen favored by moderate grazing is the legally protected C. magyarica. Short spells of low-intensity grazing can promote the species richness of cryptogams in the community.

The present part of the series of miscellaneous new records provides the records of Radiola linoides reported for the fi rst time from the Zemplén Mts, and as a confi rmation of the occurrence of the species in Hungary. Partly sympatrically, Centunculus minimus is reported as a new species from the Zemplén Mts with a number of localities. One invasive bryophyte species Campylopus introflexus is reported newly from Colocense and Praematricum biogeographical regions in Hungary and an additional occurrence in Somogy County is mentioned. An introduced fungus, Clathrus archeri is reported for the fi rst time from the Ciuc Mts largely expanding the known area of the species in Romania to the south. A frequently overlooked fern, Dryopteris affinis is newly reported from the Visegrád Mts and also from the Pinka Gorge in the Vas Mts. A remarkable new occurrence of Primula farinosa in Bakonyalja and additional records of Cuscuta campestris in W Hungary are also provided here.

... As a result of a few targeted studies the bryophyte was found mainly in pine plantations, furthermore its largest population appeared in disturbed native forests with an acidic soil surface (Szűcs et al. 2014). More recently, its presence has been detected in Transdanubian region (Somogy and Tolna County) and in Praematricum (Bács Kiskun County) (Csiky et al. 2017, Matus et al. 2018). ...
