The loculoascomycete Moristroma quercinum sp. nov. and Moristroma japonicum sp. nov. are described from Northern Europe (Denmark, Lithuania, Sweden) and Japan, respectively. M. quercinum is reported from wood of Quercus robur and Q. petraea, and M. japonicum is reported from wood of Quercus mongolica var. grossoserrata. Ascostromata of both species were found on hard heartwood of attached or shed branches. The two new species differ from the type species of the genus, M. polysporum, by the presence of pycnidia, and by the size of ascostromata, asci and ascospores. Drawings illustrate ascostromata, pycnidia, asci, hamathecium and ascospores of the two new species. A phylogenetic analysis suggests that Moristroma belongs to the Chaetothyriomycetes, rather than to the Dothideomycetes as previously suggested.
