The genus Pyrenophora includes 191 species [http://www.speciesfungorum.org/Names/names.asp?strGenus=Pyrenophora] , including the following plant pathgenic species: " P. teres", " P. graminea" and " P. tritici-repentis".

P. teres (teleopmorph Drechslera teres) makes up to 3 conidia per conidiophore. It infects plants with an appressorium. It grows biotrophically in the first infected plant cell but then switches to a necrotrophic growth mode. During necrotrophic growth the fungus can only be found in the plant apoplast but not within plant cells.
