New lichen records from Bukovské vrchy Mts ( NE Slovakia )

interesting findings of 100 lichens from the Bukovské vrchy Mts (Biosphere Reserve Poloniny, Slovak part) are reported as the result of recent survey work. two species are new for Slovakia: Fellhanera gyrophorica and Rinodina efflorescens, and 34 species are reported for the first time from the studied area. the new records for the country are shortly commented as well as ecological aspects of Agonimia repleta, Strigula stigmatella, Gyalecta ulmi and Belonia herculina.

international level, is the old-growth forest Stužica, which spreads over the valley of the Stužická rieka.
the mountains fall within Unesco Biosphere Reserve Poloniny being the only trilateral reserve, unfolding on the area of three countries -Poland, Ukraine and Slovakia.Lichen diversity of Polish part comprises up to 600 species (k i s z k a 1997, 1999; k i s z k a , k o ś c i e l n i a k 1998,2001).Recent lists of lichens from ukrainian part include almost 430 taxa (c o p p i n s et al. 1998, 2005).
the lichens in the Slovak area, were explored for the first time only in 1931 and 1932, when Josef nádvorník, a teacher in the "Zakarpatska oblast", visited the place Riaba skala during one-day excursions (e.g. S e r v í t , n á d v o r n í k 1935).After three decades the mountains were revisited by ivan Pišút (P i š ú t 1964, 1966), later by Jiří Liška (L i š k a 1980). in 1989 ivan Pišút and Anna Lackovičová started contemporary and targetted research here, later Anna Guttová and Zdeněk Palice joined them.Part of the results were already published (e.g.P i š ú t , L a c k o v i č o v á 1992; P i š ú t 1995; G u t t o v á 1997; L a c k o v i č o v á 1998; L a c k o v i č o v á , G u t t o v á 2006), further taxa were included in the Checklist of Eastern Carpathian lichens without localities (K o n d r a t y u k et al. 2003).In total, almost 300 species were recorded here.the number of species reflects also the size of the area of Poloniny in Slovakia (out of the three parts is the smallest one) and smaller diversity of substrata.

the most interesting results of lichenological research conducted in 1989-1994 and 2002-2004 in the territory of Bukovské vrchy Mts are presented.the specimens are kept in the collection of the Institute of Botany, academy of Sciences of the czech Republic, Průhonice (PRA) and of the institute of Botany, Slovak Academy of Sciences, Bratislava (specimens without reference to the herbarium).
the list reports and documents the most interesting findings of 100 lichens from Bukovské vrchy Mts (mostly from the small scale protected areas -national nature Reserves and national Reserves), two of which are new for Slovakia and 34 new for the Bukovské vrchy Mts.
Several findings are interesting from ecological viewpoint.Agonimia repleta, obligatorily growing as an epiphyte, but recorded also on a clayey soil (C z a r n o t a 2003), was found on sandstone pebbles in the studied area.an epiphyte Strigula stigmatella was also once recorded on sandstone pebble here.Similarly, Gyalecta ulmi, was collected in Bukovské vrchy Mts on dead bryophytes on a sandstone boulder.there are more records of this species from limestone or lime containing rocks in Slovakia, e.g. from Bachureň Mts., Branisko Mts., kysucká vrchovina Mts, Pieniny Mts or tatry Mts (L a c k o v i č o v á , G u t t o v á 2006).Belonia herculina, collected mostly in the Carpathians -apart from outlying localities in Slovenia and Caucasus (A r u p et al. 2001; o t t e 2004), was reported only from beech in Slovakia.now it was collected on Acer pseudoplatanus.a second specimen from A. pseudoplatanus was found during revision of the material kept in BRA (nízke tatry Mts, Latiborská hoľa, 1200 m, 1972, leg.Vězda, BRA; not published so far).
