Jakab, Gusztáv: Contributions to the knowledge of the bryophyte flora of the SE Carpathians (Romania)

25. Tocsila Stream: Mosses were collected from the rocks and walls of the bank of the Tocsila Stream near Erzsébetbánya (600 m above sea level). RESULTS AND CONCLUSIONS A total of 200 bryophyte taxa have been recorded (Appendix) from the Rozsály-Kőhát Mts and Lápos Mts. The Great Sapinta Waterfall and its surroundings have a luxuriant bryophyte vegetation. More than 60 bryophyte species have been registered in this site. This fact justifies the need of urgent conservation of this waterfall. The occurrence of Cololejeunea calcarea and Plagiobryum zierii at the Great Sapinta Waterfall is especially remarkable because of the acidity of the area. Cololejeunea calcarea is new in the SE Carpathians. Barbilophoziafloerkei, Hygrohypnum molle, H. ochraceum and Riccardia chamaedryfolia are quite rare in the SE Carpathians. Radula lindenbergiana found at the Ursului Fountain is quite rare in the SE Carpathians. Porella cordaeana, Hygrohypnum eugyrium and Calypogeia fissa are new in the SE Carpathians. Tayloria tenuis is an arctic moss growing on wood. Very rare in the Carpathians. So far reported only from the E Carpathians (STEFUREAC 1986) and new in the SE Carpathians. Leucobryum juniperoideum could be an overlooked species in the Carpathians. I think it could be more frequent in the Picea zone than it was thought before. Plagiothecium undulatum is a subatlantic element which is quite frequent in the investigated area. It is interesting to note that as it was shown earlier (KÁRPÁTI 1941), there are numerous peatbogs in the area that support arctic and alpine elements. Such plant species include Andromeda polifolia, Carex pauciflora, Drosera rotundifolia, Empetrum nigrum, Eriophorum vaginatum, Ligularia sibirica, Lycopodium alpinum, Melampyrum saxosum, Pinus mugo, Salix aurita, Vaccinium oxycoccos, V. uliginosum etc. In my opinion the occurrence of alpine bryophytes is not so surprising after all. Calliergon stramineum, Drepanocladus exannulatus, Sphagnum cuspidatum are common in the area. Dicranella palustris, Drepanocladus fluitans, D. revolvens, D. vernicosus, Homalothecium nitens, Sphagnum riparium, S. russowii and S. warnstorfii occur as well. Sphagnumpylaesii (det.: Erzsébet Szurdoki) found on Lake Demeter is extremely local in Europe (DANIELS and EDDY 1985), and this is the first occurrence reported from the Carpathians.
