摘 要：Sexual morph of didymellaceous taxa are characterized by their ascomata with relatively thin peridium,cylindric-clavate to clavate,short-pedicellate or apedicellate asci,hyaline to brown,1-septate to muriform *** asexual morphs are coelomycetous and comprising pycnidial or acervulus conidiomata,phialidic,hyaline conidiogenous cells and hyaline or pale brown,septate or aseptate *** majority of these cosmopolitan species are plant associated fungi which can be pathogens on a wide range of hosts and some species are of particular relevance for quarantine *** studies have significantly improved the taxonomy and systematics of didymellaceous taxa based on molecular *** contrast to the accurate and detailed studies on the asexual morphs which are common obligate pathogens,information on their usually saprobic sexual morphs is still *** these phenotypically diverse species,spore characteristics are quite unique as most have hyaline spores with 0-1 septum,while only Neomicrosphaeropsis and Didymellocamarosporium are reported as producing pigmented,muriform *** dematiaceous muriform spores are characteristic of a considerable number of species that may be quite divergent in other *** taxonomic investigations on the diversity of didymellaceous taxa,we have isolated species from Alhagi pseudalhagi,Coronilla emerus,Cytisus sp.,Elaeagnus angustifolia and Spartium junceum in Italy,Russia and Uzbekistan.A comprehensive phylogeny,based on four loci(ITS,LSU,rpb2 and tub2)is used to infer species *** morphological descriptions and in-depth phylogenetic investigations of five new species *** coronillae-emeri,Microsphaeropsis spartii-juncei,Neomicrosphaeropsis alhagi-pseudalhagi,*** and *** are presented.
