The present part of the series provides miscellaneous new records of six lichen-forming, two lichenicolous and six flowering plant species from Hungary, Romania and Serbia. New Hungarian chorological records for the flowering plants are: Juncus sphaerocarpus new for the Putnok Hills and Sorbus semiincisa for Mezőföld. The second recent occurrence of Crepis mollis subsp. succisifolia very rare in Hungary is presented here from the Bakonyalja region. Sporobolus cryptandrus agressively spreading in the Hungarian sandy areas was found in the Nyírség area. The old records of Lappula heteracantha in the Mezőföld (Balatonkenese) and those of Sherardia arvensis in the Zemplén Mts are confirmed. Regarding the lichen-forming fungi Bacidia fraxinea and Toniniopsis subincompta are new to the Vértes Mts (Hungary), Bacidia rubella is new to Mt Pilis (Hungary), Flavoparmelia soredians is new to the Hajdúság area (Hungary), and Oxneria huculica is new to Romania and Serbia. Second or further additional records are reported for Bacidia ru bella (Vértes Mts), and for Parmotrema perlatum (Nyírség area). Several new Hungarian records of the lichenicolous fungi Scutula tuberculosa and Stigmidium solorinarium for the Bakony, Buda, Bükk and Vértes Mts are also listed here. [ABSTRACT FROM AUTHOR]
