Its asexual morphs are coelomycetous and comprising pycnidial or acervulus conidiomata, phialidic, hyaline conidiogenous cells, hyaline or pale brown, septate or aseptate conidia. The 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 measures. Recent studies have significantly improved the taxonomy and systematics of didymellaceous taxa based on molecular phylogenetics. In 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 limited. Among these phenotypically diverse species, spore characteristics are quite unique as most of them have hyaline spores with 0?1 septum while only Neomicrosphaeropsis and Didymellocamarosporium are reported as producing pigmented, muriform spores. These dematiaceous muriform spores are characteristic of a considerable number of species that may be quite divergent in other characters. During taxonomic investigations, we have isolated taxa 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 relationships. Comprehensive morphological descriptions and in-depth phylogenetic investigations of five new species viz. Ascochyta coronillae-emeri, Microsphaeropsis spartii-juncei, Neomicrosphaeropsis alhagi-pseudalhagi, N. cytisicola and N. elaeagni are presented} }
