A total of 18 isolates of Cryptocoryneum species, which include two strains from Africa, three from Europe and 13 from Japan, were phylogenetically analysed based on nuc rDNA internal transcribed spacers 1 and 2 (ITS), and partial sequence of the translation elongation factor 1? gene (TEF1) sequences. Phylogenetic analysis indicated that the Cryptocoryneum species form a monophyletic clade and are related to Lophiotrema (Lophiotremataceae) and Aquasubmersa (incertae sedis) in the Pleosporales, Dothideomycetes. We observed the holotype specimens of C. fasciculatum, C. hysterioides and Torula uniformis and concluded that these species are conspecific and C. hysterioides has priority. Although C. hysterioides has long been regarded as a synonym of C. condensatum, we treated C. hysterioides as a distinct species within the genus. We found that there are several cryptic species morphologically similar to C. condensatum sensu lato. These species, however, can be separated by conidial size, the number of conidial arms, and the number of conidial septations, and these characters seem to be informative for species discrimination of Cryptocoryneum. A total of seven new species, namely C. akitaensis, C. brevicondensatum, C. congregatum, C. japonicum, C. longicondensatum, C. paracondensatum and C. pseudorilstonei are described and illustrated.} }
