Description on the natural substrate: Colonies on natural substratum effuse, hairy, dark brown to black. Mycelium mainly immersed in the substratum. Stroma not developed. Setae and hyphopodia absent. Teleomorph: Unknown. Anamorph: Conidiophores macronematous, mononematous, solitary, erect, unbranched, straight, or slightly flexuous, multiseptate, dematiaceous, smooth, regenerating percurrently. Conidiogenous cells integrated, terminal, with crowded repeating percurrent proliferations. Conidia holoblastic, acrogenous, solitary, euseptate, curved, dematiaceous, setulate, usually aggregated in a mass. Conidial secession rhexolytic (Goh and Hyde 1998a, b).
Ecology/Substrate/Host: Saprobe on dead material of plant.
Geographical distribution: Brunei, China and India.
Description and illustration: Goh and Hyde (1998a, b).
Notes: Goh and Hyde (1998a, b) created the new genus Stratiphoromyces for S. brunneisporus, and differentiated it from other dematiaceous hyphomycetes by its unique combination of morphological characters: solitary conidiophores which regenerate percurrently like those in some species of Chloridium and Cacumisporium; conidiogenous cells which repeatedly proliferate to produce a crop of solitary, rhexolytically seceding conidia; and brown, uniseptata, curved, setulate conidia. Morphologically Chloridium and Dictyochaeta in Chaetosphaeriaceae are closely related genera but differ from Stratiphoromyces by the septate asymmetrical conidia. The genus is with two described species, S. brunneisporus and S. raghukumarensis D’Souza, S.K. Singh & Bhat (Goh and Hyde 1998b; D’Souza et al. 2002; Seifert et al. 2011). No NDA sequence data are available for phylogenetic analysis, in phylogenetic relationship with Chaetosphaeriaceae remains to be studied.
