  Due 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.

  Three new localities of the protected and endangered moss species, Grimmia plagiopodia Hedw., were discovered in 2017 in the southern part of Börzsöny Mts (North Hungarian Mountains) at Nagymaros and Kismaros villages. The authors have re-evaluated the threat-status of the species applying the most recent IUCN Red List categories and criteria. According to this, G. plagiopodia can still get the endangered (EN) status in Hungary.
