Colonies effuse, hairy, dark brown. Teleomorph: Unknown. Anamorph: Conidiophores solitary, erect, dark brown, proliferation percurrently or occasionally sympodially. Conidiogenous cells integrated, terminal, monophialidic or polyphialidic, cylindrical to clavate; collarettes cylindrical, with narrower sporulating loci. Conidia holoblastic, acrogenous, solitary, ellipsoidal, obtuse at apex, base with a distinct scar, septate, dark brown, smooth.
Ecology/Substrate/Host: Saprobe on dead material of plants.
Geographical distribution: China and Cuba Castaneda- Ruiz (1988).
Description and illustration: Castaneda-Ruiz (1988).
Notes: The genus Stephembruneria was originally described for a dematiaceous hyphomycetes found on dead culms of unidentified Gramineae species from Cuba. It is characterized by solitary and cylindrical conidiophores, mono- or polyphialidic conidiogenesis cells with cylindrical collarettes and narrow sporulating loci, and brown multiseptate conidia (Castaneda-Ruiz 1988). Kylindria, Xenokylindria and Paradischloridium are the related genera with similar conidiogenesis. However, in Kylindria and Xenokylindria the conidia are hyaline; and in Paradischloridium the collarettes in conidiogenous cells are cup-shaped and as broad as conidiogenous cell body (DiCosmo et al. 1983; Bhat and Sutton 1985a; Castaneda-Ruiz 1988).
Type species: Stephembruneria elegans Castaneda.
Other accepted species: Species Fungorum – search Stephembruneria.
