Müll. Syn.: Ceplialozia massalongi Spruce, Cephalozia compacta (Joerg.) Müll. Frib., Cephaloziella perssonii K. Müll. Some bryophytes were collected on 19 June, 1999 from rock cavities of the "Kalibáskő" rock (Harghita Mts.) on the way to the famous "Hargitaliget" fen (NYÁRÁDY 1929). This boulder is situated beside the "Tolvajos" stream opposite to the spring named "Festő-borvízkút" near the road towards Kirulyfürdő village. The cavities in the conglomerate rock were carved by the stream. Extensive mats of Cephaloziella massalongi were found in these cavities, together with Conocephalwn conicum (L.) Lindb., Lepidozia reptans (L.) Dum., Dicranella suhulata (Hedw.) Schimp., Gymnostomum aeruginosum Sm., Leptobryum pyriforme (Hedw.) Wils., Pohlia proligera (Kindb. ex Breidl.) Lindb. ex H. Arn. and Rhabdoweisia fugax (Hedw.) B., S. et G. Outside the cavities Sphenolobus minutus (Schieb, in Cranz) Berggr., Tritomaria exsecta (Schmid. ex Schrad.) Schiffn. ex Loeske, Amphidium mougeotii (B. et S.) Schimp., Bartramia halleriana Hedw., Dicranum montanum Hedw., Leucobryum juniperoideum (Brid.) C. Muell., Leucobryum glaucum (Hedw.) Aongstr. and Pohlia nutans (Hedw.) Lindb. grow on the rock. Cephaloziella massalongi is new to the bryophyte flora of Romania (see DULL 1983). Description of Cephaloziella massalongi according to Smith (1990): Probably dioecious. Plants very slender, in yellowish-green or green to reddish-brown or blackish, sometimes extensive patches, mats or turfs. Shoots prostrate to erect, 120-280(-320) pm wide, stems branching irregularly, 40-80(-100) pm wide, dorsal cortical cells 10-16 pm wide. Leaves on sterile stems distant to approximate or subimbricate, itransversely inserted, patent to erecto-patent or with basal part patent and lobes ±erect, concave channelled, 80-100 pm long, 80-160 pm wide, margins irregularly dentate to sinuose-dentate or ientire, bilobed to 0.6-0.9, sinus acute, lobes lanceolate to narrowly triangular, (2-)4-8 cells wide at base, these cells 10-16 pm wide, walls thin and colourless or more usually thickened, some-
