DNA from 29 taxa representing 6 genera from Magnaporthaceae were sequenced and analyzed phylogenetically based on bayesian, likelihood and parsimony methods. Magnaporthaceae, encompassing genera such as Buergenerula, Gaeumannomyces, Magnaporthe, Mycoleptodiscus, Ophioceras, Pseudohalonectria and Pyricularia constitute a strongly supported monophyletic clade. Phylogenies indicate that Magnaporthaceae bears close phylogenetic affinities to the order Diaporthales and Ophiostomatales. However, there appears to be sufficient evidence to establish a new order to accommodate the Magnaporthaceae. Results also indicate that Ophioceras is probably monophyletic with the exception of O. tenuisporum. Magnaporthe salvinii is more closely related to Gaeumannomyces than M. grisea, which clusters with Pyricularia. The placement of Mycoleptodiscus coloratus and Ceratosphaeria lampadophora within the Magnaporthaceae is confirmed. Molecular data also provided further evidence to support the association of several anamorphic genera with the ascomycetous Magnaporthaceae. The phylogenetic significance of several morphologies currently used in the classification of members among Magnaporthaceae is discussed.} }
