Saprobic on submerged wood. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Conidiomata synnema, scattered or gregarious, erect, brown. Mycelium immersed in the substratum, hyaline to pale brown. Conidiogenous cells holoblastic, monoblastic, integrated, terminal, determinate, oblong, hyaline to pale brown. Conidia acrogenous, solitary, non-complanate, hyaline to brown, cheiroid, euseptate, arms vertically inserted in different planes, on a basal cell; basal cells pale brown, cuneiform, smooth, thin-walled; arms discrete, mostly divergent, cylindrical (Kodsueb et al. 2007).
Notes: The monotypic genus Aquaticheirospora is distinguished from other cheirosporous genera by synnematous conidiomata and acrogenous, euseptate, cheiroid conidia with divergent arms (Kodsueb et al. 2007). The synnematous conidiomata were thought to be not important to delimit a separated genus because the type species A. lignicola nested amongst Dictyosporium based on ITS sequence data (Cai et al. 2008). However, Boonmee et al. (2016) demonstrated that Aquaticheirospora was a morphologically and phylogenetically well-separated genus based on multigene phylogenetic analyses.
Aquaticheirospora lignicola has 3(–5) tightly packed arms on the substrate, but has
(3–)5(–10) divergent arms with a brown vacuole in culture (Kodsueb et al. 2007).
Type species: Aquaticheirospora lignicola Kodsueb & W.H. Ho.
Other accepted species: Species Fungorum – search Aquaticheirospora.
