Pseudophialophora was introduced by Luo et al. (2014) as a monotypic genus within Magnaporthaceae and typified with Pseudophialophora eragrostidis based on morphology and multigene phylogeny of SSU, ITS, LSU, MCM7, RPB1 and TEF1-α. Luo et al. (2014) introduced three new species isolated from the roots of Poaceae plants in the USA. Six new species were introduced into this genus, which were isolated from the roots of Poaceae plants in Brazil and the USA (Luo et al. 2015, Crous et al. 2017). Currently, nine species of Pseudophialophora have been isolated from grass rot (Luo et al. 2014, 2015, Crous et al. 2017, Hyde et al. 2020). Pseudophialophora are phialophora-like fungi characterized by dark septate hyphae, simple and short conidiophores, typical phialides, and oblong ellipsoidal unicellular conidia aggregated in slimy heads (Luo et al. 2014). Morphologically, Pseudophialophora is similar to Magnaporthiopsis J. Luo & N. Zhang and Gaeumannomyces Arx & D.L. Olivier in a Phialophora-like conidial state and compressed hyphae (Luo et al. 2014). Magnaporthiopsis differs from Pseudophialophora by having straight conidiogenous cells, wider ovoid conidia, and faster growth rates (Luo and Zhang 2013, Luo et al. 2014). Gaeumannomyces differs from Pseudophialophora in straight conidiogenous cells, sickle-shaped conidia, and faster growing colonies (Luo et al. 2014). Flammeopellis can be distinguished from other genera based on its morphology and phylogeny.
