1The 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 2014Fungal Diversity2014,,4:0
2DISCOMYCETES: the apothecial representatives of the phylum Ascomycota显示文摘Discomycetes are an artificial grouping of apothecia-producing fungi in the phylum Ascomycota.Molecular-based studies have revealed that the discomycetes can be found among ten classes of Ascomycota.The classification of discomycetes has been a major challenge due to the lack of a clear understanding of the important morphological characters,as well as a lack of reference strains.In this review,we provide a historical perspective of discomycetes,notes on their morphology(including both asexual and sexual morphs),ecology and importance,an outline of discomycete families and a synoptical cladogram of currently accepted families in Ascomycota showing their systematic position.We also calculated evolutionary divergence times for major discomycetous taxa based on phylogenetic relationships using a combined LSU,SSU and RPB2 data set from 175 strains and fossil data.Our results confirm that discomycetes are found in two major subphyla of the Ascomycota:Taphrinomycotina and Pezizomycotina.The taxonomic placement of major discomycete taxa is briefly discussed.The most basal group of discomycetes is the class Neolectomycetes,which diverged from other Taphrinomycotina around 417 MYA(216–572),and the most derived group of discomycetes,the class Lecanoromycetes,diverged from Eurotiomycetes around 340 MYA(282–414).Further clarifications based on type specimens,designation of epitypes or reference specimens from fresh collections,and multi-gene analyses are needed to determine the taxonomic arrangement of many discomycetes.A.H.Ekanayaka H.A.Ariyawansa K.D.Hyde E.B.G.Jones D.A.Daranagama A.J.L.Phillips S.Hongsanan S.C.Jayasiri Qi Zhao 2017Fungal Diversity2017,,6:0
3Diversity 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 2015Fungal Diversity2015,,2:0
