Classification: Helminthosphaeriaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Mycelium immersed to superficial, composed of pale brown to brown, septate, branched, smooth-walled hyphae. Conidiophores macronematous, mononematous, erect, simple or branched, straight or flexuous, pale brown, smooth-walled. Conidiogenous cells monoblastic, integrated, terminal, tapering towards the truncate apex. Conidia solitary, acrogenous, simple, ellipsoidal, pale brown to brown, smooth-walled, 1–multi-septate (adapted from Sutton 1973).
Notes: The hyphomycete genus Endophragmiella is typified by End. pallescens which was found associated with stromata of Cytospora chrysosperma (Valsaceae) on wood of Populus tremuloides (Sutton 1973). Hughes (1979) suggested that Endophragmiella maybe the sexual morph of Echinosphaeria and the synanamorph of Selenosporella. Hughes (1979) also described two specimens of Echinosphaeria canescens, one of which was accompanied by End. biseptata; and the other was related to Selenosporella (Hughes 1979). These associations are not confirmed through culture or phylogenetic analysis. Molecular data is available for End. dimorphospora (CBS 438.74) and End. taxi (CBS 614.84), but not for End. pallescens (Hernández-Restrepo et al. 2017; Vu et al. 2019). End. dimorphospora nests in Helminthosphaeriaceae, but End. taxi is closely related to members of Tubeufiales (Dothideomycetes) (not shown).
