This is the twelfth contribution to the Fungal Diversity Notes series on fungal taxonomy, based on materials collected from many countries which were examined and described using the methods of morphology, anatomy, and strain culture, combined with DNA sequence analyses. 110 taxa are described and illustrated, including five new genera, 92 new species, eight new combinations and other taxonomic contributions (one new sequenced species, one new host and three new records) which are accommodated in 40 families and 1 incertae sedis in Dothideomycetes. The new genera are Amyloceraceomyces, Catenuliconidia, Hansenopezia, Ionopezia and Magnopulchromyces. The new species are Amyloceraceomyces angustisporus, Amylocorticium ellipsosporum, Arthrinium sorghi, Catenuliconidia uniseptata, Clavulina sphaeropedunculata, Colletotrichum parthenocissicola, Coniothyrium triseptatum, Cortinarius indorusseus, C. paurigarhwalensis, C. sinensis, C. subsanguineus, C. xiaojinensis, Diaporthe pimpinellae, Dictyosporella guizhouensis, Diplodia torilicola, Fuscoporia marquesiana, F. semiarida, Hansenopezia decora, Helicoarctatus thailandicus, Hirsutella hongheensis, Humidicutis brunneovinacea, Lentaria gossypina, L. variabilis, Lycoperdon lahorense, L. pseudocurtisii, Magnopulchromyces scorpiophorus, Moelleriella gracilispora, Neodevriesia manglicola, Neodidymelliopsis salvia, N. urticae, Neoroussoella magnoliae, Neottiella gigaspora, Ophiosphaerella chiangraiensis, Phaeotremella yunnanensis, Podosphaera yulii, Rigidoporus juniperinus, Rhodofomitopsis pseudofeei, Russula benghalensis, Scleroramularia vermispora, Scytinopogon minisporus, Sporormurispora paulsenii, Thaxteriellopsis obliqus, Tomentella asiae-orientalis, T. atrobadia, T. atrocastanea, T. aureomarginata, T. brevis, T. brunneoflava, T. brunneogrisea, T. capitatocystidiata, T. changbaiensis, T. citrinocystidiata, T. coffeae, T. conclusa, T. cystidiata, T. dimidiata, T. duplexa, T. efibulata, T. efibulis, T. farinosa, T. flavidobadia, T. fuscocrustosa, T. fuscofarinosa, T. fuscogranulosa, T. fuscopelliculosa, T. globospora, T. gloeocystidiata, T. griseocastanea, T. griseofusca, T. griseomarginata, T. inconspicua, T. incrustata, T. interrupta, T. liaoningensis, T. longiaculeifera, T. longiechinuli, T. megaspora, T. olivacea, T. olivaceobrunnea, T. pallidobrunnea, T. pallidomarginata, T. parvispora, T. pertenuis, T. qingyuanensis, T. segregata, T. separata, T. stipitata, T. storea, Trichoderma ceratophylletum, Tyromyces minutulus, Umbelopsis heterosporus and Xylolentia reniformis. The new combinations are Antrodiella descendena, Chloridium macrocladum, Hansenopezia retrocurvata, Rhodofomitopsis monomitica, Rh. oleracea, Fuscoporia licnoides, F. scruposa and Ionopezia gerardii. A new sequenced species (Graphis supracola), one new host (Aplosporella prunicola) and three new geographical records (Golovinomyces monardae, Paradictyoarthrinium diffractum and Prosthemium betulinum), are reported.
