Papp, Beáta, Ódor, Péter; Erzberger, Peter: Preliminary data about the present Hungarian local populations of rare European bryophytes
data: 01.05.1958 and 18.06.1958, leg. and det. Boros, Á., Vajda, L.; 03.05.1958 and 28.09.1959, leg. and det. Boros, Á. Two small patches of ca 10 cm diameter were found on the northeastern end of the rock wall on a N and an E facing site, respectively. It was mixed with Rhizomnium punctatum (Hedw.) Kop. and Racomitrium aquaticum (Schrad.) Brid. Desmatodon cernuus (Hueb.) B., S. et G. is a boreal, montane species, occurring mainly on calcareous soil, frequently in maritime habitats in W Europe. Rare according to the RDB. In Hungary, it was collected once, 100 years ago, on sunny phyllitic rocks at Kőszeg city, leg. Latzel, A., det. Loeske, L. A new locality was discovered in the Kiskunság National Park (PAPP and RAJCZY 2000, PAPP and RAJCZY in press). New occurrence: Bács-Kiskun county, on alkali soil at lake Szappanszék near Fülöpháza, 300 m a.s. I., 21.07.1977, leg. Rajczy, M., det. Papp, B.; and 09.04.1999, leg. Rajczy, ML, Papp, B., Szurdoki, E., det. Papp, B. In 1999 it occurred on the shore of the lake about 10 m from the water behind the zone predominated by Drepanocladus aduncus (Hedw.) Warnst. It forms patches of 1-2 cm diameter. The total area covered is about 20 cm 2 . It lives together with Didymodon tophaceus (Brid.) Lisa, Bryum algovicum C. Mucll., Drepanocladus aduncus (Hedw.) Warnst. Dicranum viride (Sull. et Lesq.) Lindb. is a subcontinental, montane species. It occurs on tree trunks in humid forests, mainly on the lower part of the trees. It is included in the Bern Convention and in the Habitat Directives; it is vulnerable according to the RDB. It was already known from 10 localities in the Bükk Mts and 9 from other parts of Hungary (ERZBERGER 1999). New occurrence: Borsod-Abaúj-Zemplén county, Bükk Mts, Répáshuta, Őserdő, in semi-natural montane beech forest, on the base of a beech snag, 850 m a. s. I., 03.09.1999, leg. Papp, B., det. Papp, B. It forms patches of about 2 cm diameter. It covers about 120 cm 2 on the tree from the base to ca 60 cm high. It was associated with Dicranum montanum Hedw., Dicranum scoparium Hedw., Dicranum tauricum Sap., Paraleucobryum longifolium (Hedw.) Loeske. The abundance of Dicranum tauricum Sap., which is somewhat similar to D. viride and is possibly expanding its area in Hungary (ERZBERGER 1999), was higher in the same habitat of the forest. Neckera pennata Hedw. is a subboreal species. It lives mainly on tree trunks. It is a vulnerable species in Europe according to the RDB.
