Classification:  Incertae sedis, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

 

Saprobic on decaying submerged plant substrates. Asexual morph: Colonies effuse, scattered, dark brown, glistening. Mycelium partly superficial, partly immersed in the substratum, composed of brown, septate, branched hyphae. Conidiophores macronematous, mononematous, solitary, cylindrical, slightly tapering towards the apex, straight or slightly flexuous, septate, mid to dark brown, sometimes reduced to a single conidiogenous cell, truncate at the apex. Conidiogenous cells monoblastic, integrated, terminal, brown. Conidia acrogenous, solitary, fusiform or obclavate, truncate at the base, septate, mid to dark brown, paler towards the apex. Sexual morph: Undetermined.

Notes: Pseudostanjehughesia was introduced by Yang et al. (2018) with a single freshwater species, Pseudostanjehughesia aquitropica. Luo et al. (2019) introduced the second species to this genus, and both were collected from freshwater habitats. Currently, Pseudostanjehughesia is placed in genera incertae sedis within Diaporthomycetidae. Our phylogenetic analysis showed that Pseudostanjehughesia formed a distinct clade, sister to Acrodictyaceae and the clade of Proliferophorum thailandicum and Platytrachelon abietis within Diaporthomycetidae, with a stem age of 111 MYA. Both phylogeny and divergence time are support this genus can be a new family.

Other accepted species: Species Fungorum – search Pseudostanjehughesiaceae.
