Komplex biodiverzitás-tanulmányok kéregtelepű zuzmótaxonokon. II. További taxonok, újabb módszerek = Complex biodiversity studies on crustose lichens II. Further taxa, new methods

Osszeallitottuk a hazai zuzmok (lichenizalt gombak) 196 nemzetseghez tartozo 864 fajanak es a zuzmolako mikrogombak 38 nemzetseghez tartozo 54 fajanak revidealt fajlistajat. Florisztikai kutatasaink eredmenyekent Magyarorszag florajara 29 zuzmofajt es 3 mikrogombafajt ujkent mutattunk ki. Kozreműkodtunk 8 zuzmofaj (Cetraria aculeata, Cladonia arbuscula, C. magyarica, C. mitis, C. rangiferina, Usnea florida, Xanthoparmelia pseudohungarica es X. subdiffluens) torvenyes vedelmenek elereseben (23/2005(VIII.31) KvVM; 18/2008(VI.19.) KvVM). Igazoltuk 3 hazai Toninia faj (T. opuntioides, T. physaroides es T. sedifolia) kulonallo előfordulasat, es kisebb kulonbsegeket mutattunk ki a populaciok kozott ITS, nucLSU es nucSSU szekvenciak alapjan. A T. physaroides szekvenciai ujak a GenBank adatbazis szamara. E fajok előhely-preferenciaja kulonbozott a talajreteg-vastagsag es a talajkarbonat-tartalom vonatkozasaban. HPLC vizsgalatunk jelentős elterest mutatott ki az elterő kornyezetminősegű előhelyek zuzmopopulacioiban HPTLC-vel azonositott zuzmoanyagok mennyisegeben. A valtozasok genetikai hatterenek kutatasa azonban nem jelzett kulonbseget. A tropusi esőerdők bioindikaciojaban jelentős szerepet betoltő levellako keregtelepű zuzmok ujabb sved es magyar (Thor 1985, Pocs 2003) Fiji szigeteki gyűjteseinek feldolgozasa alapjan a teruletről igazolt 78 faj kozul 70 a teruletre uj adat, 3 faj pedig a tudomanyra nezve is uj (Calopadia fijiensis, Porina kadavuensis, P. taveuniensis). | The checklist of Hungarian lichen-forming fungi was compiled. It contains 864 species of 196 genera. Further 54 lichenicolous fungi of 38 genera are also listed. From recent collections 29 lichen species and 3 species of lichenicolous fungi are new for the flora of Hungary. Due to our research activity 8 lichen species (Cetraria aculeata, Cladonia arbuscula, C. magyarica, C. mitis, C. rangiferina, Usnea florida, Xanthoparmelia pseudohungarica and X. subdiffluens) became protected by law (23/2005(VIII.31) KvVM; 18/2008(VI.19) KvVM). Independent occurrence of 3 Toninia species (T. opuntioides, T. physaroides and T. sedifolia) and slight differences among their populations were justified by ITS, nucLSU and nucSSU sequences. The sequences of T. physaroides are new for database GenBank. Habitat preferences of these species are different in thickness and carbonate content of soil under lichen thalli. According to HPLC investigations of lichen substances identified by HPTLC from various environmental conditions differ quantitatively. However, no molecular genetic differences affected by these conditions were detectable. Foliicolous crustose lichens important in bioindication of tropical rainforests were studied in recent Swedish and Hungarian (Thor 1985, Pocs 2003) collections from Fiji Islands. From the 78 species currently known, 70 are new for the investigated area, 3 species (Calopadia fijiensis, Porina kadavuensis, P. taveuniensis) are also new for science.
