| 1 | Occultocarpon,a new monotypic genus of Gnomoniaceae on Alnus nepalensis from China显示文摘Microfungi in the Gnomoniaceae(Diaporthales,Ascomycetes)comprise species commonly reported as pathogens and endophytes on trees and herbaceous hosts primarily from temperate forests of North America,Europe,and Japan.The diversity of Gnomoniaceae in China is poorly known,although several plant families that occur there specifically the Betulaceae are considered important hosts.An exploratory trip to Yunnan,China,resulted in the discovery of several members of the Gnomoniaceae.In this paper a new monotypic genus,Occultocarpon and its species,O.ailaoshanense,are described and illustrated.A phylogeny based on three genes(LSU,rpb2,tef1-α)reveals that O.ailaoshanense belongs to the Gnomoniaceae and forms a branch distinct from the currently known genera.Occultocarpon ailaoshanense is characterized by perithecia with thin,central to eccentric necks in groups embedded in a stroma and oblong elliptical-elongated,one-septate ascospores.Occultocarpon ailaoshanense occurs on the bark of branches of Alnus nepalensis(Betulaceae)in Yunnan,China. | Luis C.Mejía Amy Y.Rossman Lisa A.Castlebury Zhu L.Yang James F.White Jr | 2012 | Fungal Diversity2012，，1： | 0 |
| 2 | Phylogeny and taxonomy of Ophiognomonia(Gnomoniaceae,Diaporthales),including twenty-five new species in this highly diverse genus显示文摘Species of Ophiognomonia are leaf-inhabiting endophytes,pathogens,and saprobes that infect plants in the families Betulaceae,Fagaceae,Juglandaceae,Lauraceae,Malvaceae,Platanaceae,Rosaceae,Salicaceae,and Sapindaceae.Based on extensive collecting,this speciesrich genus is now known to have a world wide distribution in primarily temperate areas,although some species are known from the subtropics.Analyses of DNA sequences from three markers including guanine nucleotide-binding protein subunit beta-like protein(MS204),translation elongation factor 1α(tef-1α),and the ITS region including ITS1,5.8 S rDNA and ITS2 regions(ITS)were used to define phylogenetic species in Ophiognomonia.Host plant association correlated with these species.Twenty-five new species of Ophiognomonia and two new combinations are proposed with descriptions and illustrations.In addition,descriptions and illustrations are provided for 12 other species of Ophiognomonia.A key is provided to the 45 currently accepted species of Ophiognomonia.The disposition of additional names in Ophiognomonia is also discussed. | Donald M.Walker Lisa A.Castlebury Amy Y.Rossman Luis C.Mejía James F.White | 2012 | Fungal Diversity2012，，6： | 0 |
