[3] The fungus lives best in drier humid conditions, explaining why it is most often found in the soils of Australia, South Africa, and the Southeastern United States.

[1][4] Compared to the fruiting bodies of other Magnaporthe species, rhizophila is considered faster growing (0.8 cm/d at 28 °C)[4] with slightly longer and wider conidial cells.

[7] The fungus has an appressorium[5] structure which functions to elicit effector hormones to increase host susceptibility (2 clade-specific types of small specific proteins (SSP) [8]).

[1] M. rhizophila has darkly pigmented hyphae, composing mycelia that has a gray-brown color, darker than species in the rest of its family.

Magnaporthe rhizophila does not necessarily require much water to survive, localizing in drier humid regions of Australia, South Africa, and the Southeastern United States.

Rhizophila belongs to the Magnaporthe family based on its ascospore morphology; however, it has been considered for the Gaeumannomyces because they also produce phialophora-like anamorphs instead of sympodial pyricularia.
