Abstract

Based on morphology and DNA sequences of SSU, ITS, LSU, MCM7, RPB1 and TEF1 genes, we describe four new species in Magnaporthaceae that are associated with grass roots collected from New Jersey Pine Barrens. A new genus, Pseudophialophora, is erected to accommodate three species, which is characterized by slow growth on potato dextrose agar, curved conidiogenous cells without a conspicuous collarette at the apex and oblong ellipsoidal conidia. Pseudophialophora eragrostis, P. panicorum and P. schizachyrii are assigned to this genus. A new species of Magnaporthiopsis also is reported and named as M. panicorum. Distinctions between them and phylogenetic relationships with other Magnaporthaceae taxa are discussed.
