Resumo: 	Based on newly obtained 28S rDNA sequences from Roselliniella atlantica and R. euparmeliicola sp. nov., the genus Roselliniella has to be placed in Hypocreales and not in Sordariales; however, the family placement could not be resolved from the sequences obtained. The mature ascospores are single-celled and brown, but young ascospores are hyaline and sometimes have a median septum. The new species occurs on a Parmelia s.str. species in China, and differs in 24 nucleotide substitution positions in the nu-LSU rDNA region and ascospore size from R. atlantica. In this case, small variations in ascospore sizes and shape prove to be phylogenetically and taxonomically informative. The two species occur in the same clade with 95 % jack-knife support. Roselliniella atlantica occurs on Xanthoparmelia and Melanohalea species in Europe, whereas R. euparmeliicola was found on the species of Parmelia s.str. DNA was successfully recovered from a dried specimen of R. atlantica collected in 1992. Two unidentified fungi were also recovered from the Chinese specimen, and these belong to Sordariomycetidae and Dothideomycetes; whether these two are additional fungi living endolichenically in the lichen host, saprobes, or contaminants could not be ascertained.
