Ludwigsstädter Str. 51, D-96337Ludwigsstadt, Germany All available specimens of Scbistidium (collected in Hungary) in Hungarian herbaria (BP, EGR and private herbaria) and collections of the first author (B) were revised. The following 15 taxa were found to occur in Hungary: Scbistidium apocarpum, S. brunnescens subsp. brunnescens, S. brunnescens subsp. griseum, S. confertum, S. confusum, S. crassipilum, S. dupretii, S. elegantulum, S. ßaccidum, S. belveticum, S. lancifolium, S. papillosum, S. platyphyllum (new to South-Eastern Central Europe), S. pruinosum, and S. robustum. All except S. apocarpum, S. brunnescens subsp. brunnescens, S. crassipilum, S.

ßaccidum and S. belveticum ate new to Hungary. Descriptions, illustrations, distribution maps and a key are provided. Some taxonomic, bryogeographical and conservation issues ate briefly discussed. Key words: bryophytes, distribution maps, habitat requirements, illustrated key, Scbistidium platyphyllum INTRODUCTION Since the revision of the Scbistidium apocarpum complex by BLOM (1996, 1998), his concepts - developed for the taxa found in Scandinavia have been widely and rather successfully applied in other parts of Europe (BLOCKEEL and LONG 1998, GRIMS 1999, HOLZ 2000, CASAS et al 2001, CORTINI-PEDROTTI 2001, SOTIAUX and VANDERPOORTEN 2001, SIEBEL 2003, MÜLLER 2004, SMITH 2004, CASAS et al. 2006, BLOM et al. 2006, IGNATOV et al. 2006, IGNATOVA et al. 2006, MEINUNGER and SCHRÖDER 2007). A recent molecular study seems to support the narrow species concept of Blom (GORYUNOV et al. 2007). As information on the distribution of taxa in a wider geographical area is accumulating, their ecological profile and additional knowledge about their variability is becoming more precise as well. At the same time, some new species have been described (BLOM 1998, BLOM and LÜTH 2002). Studia Botanica Hungarica, 39, 2008 Hungarian Natural History Museum, Budapest
