Magnaporthaceae

Rice leaves infected with Magnaporthe grisea, copyright International Rice Research Institute.

Belongs within: Magnaporthales.

The Magnaporthaceae are a group of fungi usually necrotrophic on the roots of grasses (Kirk et al. 2001).

Characters (Kirk et al. 2001): Stromata absent. Ascomata perithecial, black, immersed in plant tissues, usually with long hairy necks. Interascal tissue of thin-walled tapering paraphyses. Asci more or less cylindrical, persistent, fairly thick-walled, without separable layers, with large apical pore surrounded by often J+ apical ring. Ascospores septate, often filiform, often with middle cells pigmented, without germ pores, without sheath. Anamorphs varied, hyphomycetous, usually with pigmented conidiogenous cells. Sclerotia sometimes formed, appressoria usually present.
