Abstract

The genus Coniochaeta is an important ascomycete because its members live in diversified habitats and nutritional modes. In this study, two new species, C. acaciae and C. coluteae, are introduced from dead branches of Acacia sp. and Colutea paulsenii Freyn (both Fabaceae) respectively from Uzbekistan, based on morphological and phylogenetic studies. Analyses of combined ITS and LSU sequence data with Genealogical Concordance Phylogenetic Species Recognition (GCPSR) and comparison of similar taxa, provide evidences for placement of these new species in Coniochaeta, as distinct lineages.
