| 1 | The complex of Diplodia species associated with Fraxinus and some other woody hosts in Italy and Portugal显示文摘Studies on the taxonomy and phylogeny of Diplodia have been hampered by the lack of an ex-type culture linked to the holotype of D.mutila,which is the type of the genus.In this study a large collection of Diplodia strains,obtained from ash and other woody hosts showing V-shaped cankers and branch dieback,were identified based on morphological characters and DNA sequence data from ITS and EF1-α loci.Results of combined morphological and phylogenetic analyses showed that the Fraxinus isolates from Italy,the Netherlands,Portugal and Spain belong to three distinct species namely Diplodia fraxini,Diplodia mutila and Diplodia subglobosa sp.nov.An epitype was designated for Diplodia mutila,with associated ex-epitype cultures.The name D.fraxini is re-instated and a neotype designated.Two species,Diplodia seriata and Diplodia pseudoseriata were reported for the first time on Fraxinus spp. | A.Alves B.T.Linaldeddu A.Deidda B.Scanu A.J.L.Phillips | 2014 | Fungal Diversity2014，，4： | 0 |
| 2 | Diversity of Botryosphaeriaceae species associated with grapevine and other woody hosts in Italy,Algeria and Tunisia,with descriptions of Lasiodiplodia exigua and Lasiodiplodia mediterranea sp.nov显示文摘The diversity of Botryosphaeriaceae species associated with“Botryosphaeria dieback”of grapevine was investigated in 18 vineyards in Sardinia,Italy.Lasiodiplodia isolates obtained from different woody hosts including holm oak,sweet orange and broom bush in Italy,Algeria and Tunisia were also characterized.Morphological and cultural characteristics as well as ITS and EF1-αsequence data were used to identify the fungal isolates.Forty-eight botryosphaeriaceous isolates were obtained from 113 symptomatic grapevine samples,from which ten species were identified.Diplodia seriata was the dominant species(25%of isolates),followed by Neofusicoccum parvum(21.7%).Two species,Diplodia olivarum and D.africana are reported for the first time on grapevine.In addition,two new species namely Lasiodiplodia mediterranea sp.nov.from grapevine,holm oak and sweet orange and Lasiodiplodia exigua sp.nov.from broom bush are described.In artificial inoculation experiments conducted on excised green grapevine shoots and lignified canes as well as holm oak seedlings,L.mediterranea was shown to be an aggressive pathogen. | B.T.Linaldeddu A.Deidda B.Scanu A.Franceschini S.Serra A.Berraf-Tebbal M.Zouaoui Boutiti M.L.Ben Jamâa A.J.L.Phillips | 2015 | Fungal Diversity2015，，2： | 0 |
