© 2015, School of Science. The genera Lophiostoma, Misturatosphaeria and several other allied taxa in Lophiostomataceae are revisited. Accounts of these taxa, including their history, morphology, and family placement, based on molecular phylogeny, are provided. Type or representative specimens of Lophiostoma and Misturatosphaeria were examined and fresh specimens were obtained from Germany, Italy, Japan and Thailand. A multi-gene phylogenetic analysis of the lophiostomataceous genera Floricola, Lophiostoma, Misturatosphaeria and related taxa is provided. Sixteen genera including Lophiostoma, Lophiohelichrysum, Dimorphiopsis, Platystomum and Vaginatispora, plus eleven newly introduced genera Biappendiculispora, Alpestrisphaeria, Capulatispora, Coelodictyosporium, Guttulispora, Lophiopoacea, Neotrematosphaeria, Paucispora, Pseudolophiostoma, Pseudoplatystomum and Sigarispora are accepted in Lophiostomataceae based on morphology and phylogeny. Lophiostoma caulium, Lophiostoma arundinis and Lophiostoma caudatum are accommodated in Sigarispora. Lophiostoma winteri and Lophiostoma fuckelii are placed in the genera Lophiopoacea and Vaginatispora respectively. Three Curreya species and Misturatosphaeria claviformis are transferred to a new genus, Neocurreya. All other Misturatosphaeria species except Misturatosphaeria aurantiinotata and M. uniseptata are separated in the new genera Asymmetrispora, Aurantiascoma, Magnibotryascoma, Pseudoaurantiascoma and Pseudomisturatosphaeria based on their morphological and phylogenetic affinities. Another new genus, Ramusculicola is introduced for a new collection from Thailand. These seven new genera are accommodated in a new family Floricolaceae, together with Floricola and Misturatosphaeria. Several massarina-like species clustered as a sister clade to Amorosia littoralis and are accommodated in a new genus Angustimassarina. A new family Amorosiaceae is proposed to accommodate the genera Amorosia and Angustimassarina. The putatively named species Decaisnella formosa and Thyridaria macrostomoides form a separate clade together with a new genus Lignosphaeria which is placed in Dothideomycetes, genera incertae sedis.
