Saprobic on submerged wood. Sexual morph: Undetermined. Asexual morph: Conidiomata on natural substratum sporodochial, superficial, compact, scattered, circular or subglobose, dark brown to black, velvety. Mycelium immersed, consisted of septate, hyaline hyphae. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, monoblastic. Conidia ellipsoidal to broadly clavate, composed of medium brown, appressed cells, rounded and brown at the apex, oval to subglobose and hyaline at the base, muriform, cheiroid, non-complanate, without appendages (Li et al. 2017a).

Notes: The monotypic genus Aquadictyospora was introduced to accommodate a freshwater species A. lignicola collected from China (Li et al. 2017b; Bao et al. 2018). Aquadictyospora differs from other genera in Dictyosporiaceae by its basal hyaline cell and conidia without appendages (Li et al. 2017b; Bao et al. 2018). Aquadictyospora nested in Dictyosporiaceae with high bootstrap support (Li et al. 2017b).

 

Type species: Aquadictyospora lignicola Z.L. Luo, W.L. Li, K.D. Hyde & H.Y. Su

Other accepted species: Species Fungorum – search Aquadictyospora.
