Papp, Beáta; Erzberger, Peter: Data about the actual local populations of bryophyte species protected in Hungary
20 patches of 10 x 10 cm 2 were detected. Earlier data from here: 21.03.1937, leg. and det. Boros Á. Komárom County, Gerecse Mts, Kő-hegy at the monument Turul, Alsógalla (Tatabánya), southern slope of the hill, on soil in open limestone grassland (N 47° 35' 11.8", E 18° 24' 29.0"), ca 310 m a. s. 1., 22.04.2003, leg. and det. Erzberger, P. and Papp, B. About 10 patches of 10 x 10 cm 2 were found. Earlier data from here: 15.03.1921, 01.05.1938, 02.04.1939, leg. and det. Boros Á. New occurrence: Pest County, Pilis-Visegrád Mts, Csúcs Hill, Csobánka, western slope of the hill, on soil in open limestone grassland, ca 300 m a. s. 1., 25.04.2003, leg. and det. Erzberger, P. About 10 patches of 10 x 10 cm 2 were discovered. There are earlier data only from the neighbouring Oszoly Hill (Szepesfalvy, J., 28.04.1931, Vajda, L., 04.05.1941). Some remarks on recognising this species and on its habitat demands seem appropriate. Sterile Asterella saccata is very similar to the considerably more frequent Mannia fragrans (Balb.) Frye et L. Clark, which occurs in much the same habitats. The two species can, however, be readily distinguished by their different smells: strongly aromatic in M. fragrans, less strong and less pleasant, somewhat fishy in A. saccata, similar in smell to the alpine relative A. lindenbergiana (Nees) Arnell, but not so pronounced. Plants of A. saccata with female receptacles are easily recognised due to the single involucre of each archegonium; in the field patches of fertile A. saccata differ from fertile M. fragrans by their yellowish colour (brownish in M. fragrans). A. saccata is less of a pioneer than M. fragrans, which is often found on rather unstable, open soil. A. saccata prefers more stable and sheltered microhabitats like medium-sized, earth-filled rock fissures, more frequently in steep or nearly vertical surfaces than M. fragrans, which is mostly found on horizontal substrates. A. saccata often grows at the edge of a rock ledge, sometimes protected by overhanging tufts of grass. Frullania inflata Gottsche var. inflata is a thermophilous, sub-Mediterranean, montane element. It lives on siliceous rocks (granite, basalt, gneiss). The species is very rare throughout its range in Europe. It is known from six European countries only (SÖDERSTRÖM et al, 2002). It is vulnerable in Europe according to the RDB. Old occurrence confirmed: Zala County, Balaton-felvidék region, Tátika Hill, Zalaszántó, Tinóállás rocks at the southern slope of the hill, on shaded basalt rocks (N 46° 54.093', E 17° 15.345'), ca 350 m a. s. 1., 30.03.2002, leg. and det. Papp, B. and Erzberger, P. Three patches of 3 x 3 cm 2 were found on two rocks. Earlier data from here: 03.06.1955, leg. and det. Vajda, L., 30.04.1956, leg. and det. Boros, Á. and Vajda, L. New occurrence: Heves County, Bükk Mts, Szarvaskő, 10 km NNW of Eger, Vár-hegy, southern slope, on partly shaded volcanic bedrock (diabas), (UTM DU 51), ca 250 m a. s. 1., 23.04.1998, leg. Pócs, T. and Erzberger, P., det. Pócs, T. Several small patches (a few cm 2 each) were found. It is interesting that in both known sites of Frullania inflata the thermophilous Fabronia pusilla Raddi also grows.
